Answer
You need a high frequency display (120 Hz). See the link for requirements. The NEC NP 300 isn't on the list and I doubt it will work well.

3D vision with 3D Ready TV?




Khaled Al


Guys,

I've bought a couple of things but there is a couple of problems which is happening to me

- Nvidia 3D Graphic Card
- Samsung 3D TV 8 Series
- 3D Vision from Nvidia

I've got a problem when my computer starts the stereoscopic wizzard where my 3d Tv can't be detected by my PC and the Samsung doesnt have an IR immiter to place it from the device

please someone help me it's been 2 days and i can't find an answer

thank you guys



Answer
The Samsung TV does not support nVidia's 3D Vision. Only a few computer monitors support it, because they need to run at a 120Hz refresh rate. Many HDTVs run at 120Hz but the only ones currently on the market that support 3D Vision are from Mitsubishi. Here's a list of computer monitors, Mistubishi TVs and HD projectors that support 3D Vision, from nVidia's web site:

http://www.nvidia.com/object/3d-vision-requirements.html

Sorry, but you'll have to return that TV and buy one of the supported displays to get 3D Vision to work.

is it possible to view a dvd by using a multi media projector,dvd player & amplifiers only?




Sepz





Answer
If your DVD player and projector are compatible, sure. Connect your DVD video output to the video input on your projector, audio outputs to your amplifier. Are you playing a stereo amp? If so, connect your left/right outputs from the DVD to the amp, the amp to your speakers. When you set up the DVD player set it to PCM or 2 channel stereo settings, that way you won't loose the center channel track from the DVDs. Some older style DVD players don't have decoders, and so you need a digital processor to get sound, but most newer units don't need outboard decoders.

How can I hook up my DVD player to a mobile projector?




cHrysler


I have a regular home DVD player and I want to hook it up to a mobile projector. Will the projector require a certain type of connector?


Answer
Check the projector to see what sort of inputs it has.

Most projectors will accept VGA, composite-video (standard A/V cable) and s-video (gives you a better picture than composite video.) Better projectors will also accept component video and even HDMI. Some better DVD players can also output VGA as well.

Check to see if the projector also has speakers - most of them don't. If your projector doesn't have speakers, you'll need to bring some along or use whatever is at the site. Computer speakers will work, but you will need to get a RCA-to-miniplug converter so you can make the connection. Radio Shack or other electronics stores sell these.

How to convert an 8mm projector to a super 8mm?




Tj Kong


So I bought this little Argus Showmaster 500 that plays 8mm film, but I have all super 8, and I read this article: http://www.ehow.com/how_7774363_convert-projectors-super-8mm-projectors.html
and it seems like all you would need to do is switch out the 8mm sprockets to super 8 sprockets. does this sound right?



Answer
The sprockets are only part of it.

You would also need to remove the aperture plate in the film gate
and enlarge its "window" to allow the larger image area of Super 8 film
to be entirely illuminated.

Got good, hard needle files? (Harbor Freight or other chinese-made ones
literally wouldn't cut it. You'd need Nicholson or other high-grade ones.)

Filing a small opening very precisely sounds like a long, tedious job to me.

Oh, and then there's the matter of aligning the lens
so that the Super 8 image would be centered in it.
That would require extensive major surgery to the projector,
and could actually prove to be impossible.


You can try converting it if you like, but you'd be far better served by acquiring
a dual-8 projector that has all the necessary adaptations in it to begin with.

What is a good 8mm sound projector?




Dan


I want to buy a good 8mm or super 8 mm projector with sound for my house. I use to be a projectionist at a movie theater but I know nothing about a good home projector, any suggestions?


Answer
I only use equipment that I inherited and haven't ventured outside of it.

I would suggest contacting these guys:

http://moviecraft.tripod.com/8mm.html

It's going to be important to buy from a shop like where they test projectors and probably repair them too. Buying from eBay is a crapshot. People often don't know anything about what they are selling much less if it works or not. It's easy to end up with neat-looking paperweights when buying vintage electrical gear from eBay.

At any rate, good luck! Sounds like a fun project and one that I also will be embarking on at some point.

projectors for outdoor cinema?




Eric O


http://www.openaircinema.us/info/elite/pact_show/id_19385372/

i found this website which sells the whole kit (is it good value for money?) - looking at the projector specifically, is 3500 lumens sufficient for a 20' screen in a relatively light-pollution-free area?
these things go up to 10.000 lumens and more, and their price proportionally - which would be the best adapted in your opinion?
Also, the projector has to work in a relatively humid environment - think Orlando by a lake. And give good screen resolution from DVD source



Answer
To pull this off, you will basically need three things:

A big enough screen that is made for outdoors. It will need to be stable in the wind. That is the hard part.

A nice bright projector (depends on the screen size. 5K lumens will probably be minimum).

A professional sound system.

You best bet is to hire an AV staging and rental company to do the whole thing. If you are going to do this on a regular basis, they can help you with purchasing the equipment and setting it up permanently.

There are plenty of companies in your area that can help you with this. Try the Yellow Pages under "Audio Visual" or "Audio Video".

Are projectors actually good for watching TV/movies? Which one is the best?










Answer
If properly set up and used, projectors can give you incredible big-screen impact with not-so-bad picture quality. There are several things to take into consideration though: making sure you have an appropriately-sized room (preferably a dark one), making sure you have a good screen of the appropriate size, the type of projector, and what not.
CRT projectors have pretty much run their course, but you'll be able to find them used (many in fairly good condition). They give arguably the best picture quality overall, with excellent color reproduction, the ability to produce true black, instantaneous response times (no blur), no native resolution (can play standard-definition and high-definition content equally well), But they are big and heavy (some weigh up to 200 pounds), need to have all three tubes replaced at the same time when one wears out or goes bad (usually every 10,000-20,000 hours of use), aren't as bright (and as such need to be used in a dark room), take a long time to set up and converge, and tended to be expensive new (although prices will vary for used models). Plus, parts are becoming harder to find.
LCD projectors have become pretty popular, as they are fairly compact and lightweight, give a bright image, and require little time to set up. However, they have poor contrast and black appears a muddy gray, suffer from the screen-door effect between pixels, have a native resolution (meaning everything must be scaled to this resolution, which can cause image quality loss), and have slow response times which can cause blurry images under fast motion. In addition, they have an expensive halogen light bulb that must be replaced every couple thousand hours of use; as the bulb gets older, colors don't appear as accurately on the screen. They also can suffer from dead pixels.
DLP projectors are another option which have gained a lot of ground in the past several years. They are also very compact and lightweight, throw a bright image, are fairly simple to set up, and give decent contrast. But they also have a native resolution to which everything must be scaled and require an expensive halogen bulb that must be replaced periodically. Furthermore, they may give the "rainbow effect" in which some viewers see various colors on the screen for a split second if they quickly move their eyes from one side to the other side of the screen while watching.
The Barco 909 CRT projector was considered by many to be the best projector ever produced, with resolution up to 2560p (3200x2560) and screen sizes up to 250 inches. But chances are you won't be able to get your hands on one.

Need help finding a projector on a budget?




MSCreative


I have a

optoma ep716r projector

at the moment connected to my ps3 but want a better one... I have found the following one of ebay

170424105472

do you think it will be any good for quality or think it will be any better than the one i have

Any help or advice would be much appreciated as i am doing it on a £300 budget



Answer
If the specs are accurate it is what you are looking for. You won't get anything better with the budget you have. This one should do, especially since it is capable of up to 1080i performance (personally I'd never use the interlaced setting on a projector) Use the 720p setting on your PS3s output and the projector input ( use the Component cables for this if tehre is no user settings) for better projection results, especially if you plan on projecting a picture larger than 40 inches diaganal. The real price driver is the resolution, this one has 800:1 so its reasonable for the amount you are budgeting. If you can find a similar one in your budget that's new with as high contrast ratio as possible, that would be your best option

I have an IN72 and it's great for a 480p especialy with the HDMI 1080i connected to an HDMI source..bbbuuuuttttt...you WILL want a true HD 720p projector,trust me..within a week or so of having ANY 480p projector you will begin to nit pick and notice flaws and natural limitations of 480p,though great for the budget minded and the entry level projector-it's still no match for a quality 720p.

Can i make a projector a tv?




love&lost


can i use a remote and switch thru cable channels as well?

please tell me the cheapest way possible to make this work.
if it is cheaper than a 32" LCD flat screen and i get more like 96" that works for me!



Answer
You need:

The projector
Either an: External HD TV tuner (if you want free HD...Samsung $150)
or a DTV converter box (free SD and a cheap box $10 plus coupon)
or a Cable box and service (whatever they might offer for a price ($30 to $100 a month)

And a screen ($50 DIY to $1,000)

PLUS a sound system ($100 to $20,000...I'm an audiophile..!)

Connect the antenna or cable to the box, converter or tuner, and connect the box output to the projector (either composite, component or HDMI)...check the connections. Audio goes to the sound system.

Definitely cheaper for a really big screen depending on the price of the projector you can get. With a receiver you can switch between TV and DVD.

I have this set-up with the Infocus X1 projector for $500.

Quality:

HDTV>DVD>DTV converter>SDTV all analog. Blu-Ray I don't know. Should be as good as over the air HDTV or better.

projector or outdoor tv?




Chance


i just had a pool built and im looking to get an outdoor projector and screen...but im also considering an outdoor tv...i know outdoor projectors arent great during the day time, but my main concern is initial cost and setup? I couldnt find any reviews or pros and cons about the two...any help would be appreciated.

Thanks



Answer
Projectors are more expensive than your standard tv. Beside that you will also need a screen and a sound system to support it. You would not be able to watch a tv program on tv with a projector. You can purchase a large screen LED or Plasma tv from Samsung or Panasonic, say a 50" and it will be brighter than a projector during the day or night showing. Also projector lamps are only rated for around 2,000 hours of use and replacement lamps can be limited. Hope this will help you out.

Answer
It's a "business" class projector, but would work fine for games on a 360. Note that the low contrast ratio (400:1) will limit the picture quality, but that isn't as important for games as for video. Similarly the video processing may be somewhat less than stellar, but again it isn't that important for games.

I can't comment on how big an image you will get since this depends on the optics and the distance you can get back from the screen. That said, in a small room a 60-70" image should be large enough (and possible).

I don't see any mention of price, but for $400-$500 or so this would be an OK choice. Just note that you will have to replace the lamp every year or so (depending on use) and that will cost ~$350 or so. As an LCD based model it may cost more than this ... if so consider a DLP based BenQ, InFocus or Optoma ... you should be able to find one in the $500 range.

I can't comment on how this compares to many other similar projectors that would work too, but Sanyo have a long history in projectors so it's a name brand.

Do you use a Media projector?

I would like to know your opinion on the display quality,to decide if it is worth throwing down the $600.+ just to find out the pictur is crappy.
thankz :)



Answer
I use an HD (720p) projector in my home theatre instead of an HDTV ... great way to get a BIG (110") picture. Just like being at the movies!

There are two main classes of projectors: business and home theatre. Both can usually be connected to a computer via a VGA input (or DVD-D).

Relative to home theatre projectors business models are usually less expensive (ca $500-$800), more portable, brighter (1500+ lumens), have poorer video processing, are noisier and often 4:3 aspect ratio (vs 16:9). In short, business models are best for bright primary colours and work OK with video sources, they are really less suited to movies, games and TV than HT models.

You really want a HT model, and these fall in three basic classes based on resolution: 480p ($500-$1000), 720p ($900+), 1080p ($1800+).

While a big picture is great -- particularly with a high contrast (2000:1 or better), HD model (720p or better), note that projectors work best in a dim/dark room (the image is washed out in bright light) and lamps need to be replaced every 2-4000 hrs and cost $300-$500 a pop. ... so projectors are not inexpensive to run.

See the link for reviews and pictures. (www.projectorreviews.com)

You can buy used projectors, but given lamps may be almost shot it is probably a good idea to by a reconditioned or new model on sale.

Good luck.

Projectors?




Pasky M


I have a few questions about projectors, I am going to get one to put in my room that I want to hook my computer up to to play games on a huge screen, i want to wathc movies on it through my computer, and I want to be able to watch local t.v. chaneels on it somehow. (my budget is I'm trying to keep it under $1000 including projection screen; I already have a sound system so that's not in my budget)

Q1: What projector should I get?
Q2: I get that the amount of lumens means how bright it can get, so what would be a good amount of lumens?
Q3: What would be a good contrast ratio? (I know the higher the better, but what is minimum amount the projector should have?)
Q4: What brand?
Q5: Where should I get it (Newegg, Bestbuy, Tigerdirect?)
Q6: Is a projector worth it instead of a tv? (I have enough space for up to 200 inches, so I thought a projecter would be a good idea, because then I could roll up the screen when I didn't need, and use the space, and it's cheaper than a big t.v.)
Ummmmm.. one thing I forgot is: is there anyway I can hook my projector up to local t.v.? (like bunny ears). I also understand that all t.v. will be digital by february of next year, so could I use a digital box to get local channels to play on my projecter?



Answer
Lets see If I can help



Q1: What projector should I get?

You want to make sure that the pj you get has a native resolution of at least 1280 X 720 so you can experience 720p HD. You should be able to find one for less than $800 and I actually just picked up an Optoma HD70 for about $650 after rebate.

Q2: I get that the amount of lumens means how bright it can get, so what would be a good amount of lumens?

Anything between 1000 and 1200 should be good. You get too many Lumens and you risk washing out the picture.

Q3: What would be a good contrast ratio? (I know the higher the better, but what is minimum amount the projector should have?)

I'd look for at least 2000:1

Q4: What brand?

There a gazillion of them but I prefer Infocus, Optoma or Epson and have had good experiences with all of them.

Q5: Where should I get it (Newegg, Bestbuy, Tigerdirect?)

For gods sake not Best Buy. Personally I have bought a few from Tigerdirect, but before I do I will do a search for the specific item on Yahoo Shopping so I can compare all of the online prices.


Q6: Is a projector worth it instead of a tv?

Absolutely! Watching HD on the big screen will BLOW YOU AWAY! I have been slowly replacing ALL my TV's with projection

About 3D home theater projectors ?




Dallasguy


I am very fan of 3D movies. I thinking to buy 3D projector in my home theater. People are saying these 3D projector are not real 3D projectors like in movie theaters and also saying we don't feel like 3D picture. How much is it True?. Is it worth to buy 3D home theater projectors? Which are the best projectors?


Answer
Its true, some projectors CAN give a bad 3D output but not if you choose the correct projector. The upcoming Panasonic PT-AE7000 can be a good option as it has an amazing contrast ratio of 300000:1 and 2000 lumens. According to review it seems great. It will be releasing in september. You should take a look at it or you can even even check out JVC projectors.

!!!!!!!3D Glasses Videos!!!!?




GaGa-4-GaG


Ok My Friend Has The Black Glasses that look Like Real Pair.It Looks Like Just Tinted sunglasses. Also He Has the Red-ish And Green 3d Glasses. Is There Any Video Online That I Can Watch in 3D That Takes My Glasses.Or Is Impossible to watch Online?


Answer
For 3d to work you have a 2d movie for the left eye only and a 2d movie for the right eye only. Then you have to block the movie for the other eye with the glasses.

With the glasses form the movie the left eye movie is passed through a filter in the projector to give it counter clockwise circular polarized light waves, and a different filter for the right eye movie to give it clockwise circular polarized light waves. Then each lens just blocks the light wave for the other eye. There are 3d televisions that can give out 2 different polarized light waves but the pixels must be made to do this. JVC is the only major company releasing one.

Anaglyph 3d which uses the colored glasses the film for the one eye is passed through one color like red to give it a red tint and the film for the other eye a different color like blue to give it a blue tint. Then the glasses must have those same two colors so one color can be blocked. there are different color combinations in use with the red and cyan(blue-green) and green and magenta being the most common. Again the colors in the 3d movie must match the colors of the glasses. Youtube has several anaglyph 3d videos. Since color is used for the 3d effect any color tv can do this format.

Xbox to projector using HDMI / Component cable?




ToastandBa


I am trying to hook up my Xbox to my projector.

I have an HDMI to component cable.
Shown here:
http://www.amazon.com/Component-Video-Stereo-Audio-Cable/dp/B001IUQB2W

With this projector:
http://cgi.ebay.com/HD-1080i-Video-Projector-HDMI-Home-Theater-DVD-Wii-/280583628675?pt=LH_DefaultDomain_0&hash=item4154166783

I have the projector set to "Y/PB/PR". Didn't work.
I had it set to "HDMI" Didn't work.
I've tried all the settings and the screen is still blue.

PLEASE HELP!

I don't want HDMI to HDMI because I want the surround sound for movies.

With just the HDMI cable or the AV cable the projector works fine.



Answer
Your cable is completely bogus. There is no such thing as a simple cable that can convert from analog to digital nor vice versa. Read the reviews on Amazon for this cable, 47 out of 53 purchasers rated the cable one star! See link below:

http://www.amazon.com/Component-Video-Stereo-Audio-Cable/product-reviews/B001IUQB2W/ref=cm_cr_pr_hist_1?ie=UTF8&showViewpoints=0&filterBy=addOneStar

Your second issue: this is not an HD projector. Right there in the ad, it says the projector's native resolution is 640 x 480. Try lowering your game's output resolution to 1024 x 768, or 720P. Sorry, but your projector is a cheap toy. You paid $200.00. You got a $200.00 projector. You get what you pay for.

Bama


Can u use a normal projector on a mac or do you need to buy one just for mac's


Answer
Yes, generally. Any Macintosh can use a projector, granted the following:
-The Macintosh has a VGA output port. Then, it works just like a PC.
-The Macintosh has a DVI output port, which in this case, it works just like a PC that has a DVI output port (you just need an adapter cable from DVI to VGA, which is common, unless your projector has a DVI input.)
-The Macintosh has some kind of mini-DVI or mini-VGA output port. This is common on Mac laptops, and usually come with adapter cords of their own.
-If you are using an older Mac with the proprietary connector, again, one needs to find the right adapter cord.

Dream projector? possible?




Yolo


Would a dream projector be possible in the near future or the not so near future? Like say you put on some comfortable gadget before you fall asleep and it records your dreams, and when you wake up you can just plug it in to the tv and see what you dreamed about if you forgot or if you had a wierd dream that is hard to explain and only seeing it would explain it to your friends.
Also maybe there could be a mode when you are asleep, your friends plug in the gadget to the tv and see what your dreaming of at the moment.

Does this dream projector gagdet seem POSSIBLE because tht would be cool.



Answer
While the concept you describe is interesting - and something similar was used in an old episode of CSI New York - it is not possible. The bio-electrical impulses that form dreams are no different in kind than brain activity in any other state of consciousness. When awake, the conscious mind can create imaginary images (as in day dreaming or memory) just as the unconscious mind creates imaginary images in dreams during sleep. But the technology of brain scans, MRIs, etc., only record and map the bio-electrical impulses. Technology cannot interpret the patterns of these impulses.

By way of explanation, consider the sort of graph produced when instruments measure the force of an earthquake. Technology can record the intensity of the disturbance, and the location of that disturbance on both the earth's surface and deep beneath the surface. Those measurements provide a lot of information. But they do not produce an IMAGE of the location in Japan or Italy or Chile or California where the earthquake takes place. To see a visible image, a different sort of technology is required. In the earthquake example, one would need to go to Japan or California and make a video recording of the visible scene.

In the case of imaginary images of the conscious or sleeping mind, no such technology exists to convert bioelectrical impulses to visual images.

3D vision with 3D Ready TV?




Khaled Al


Guys,

I've bought a couple of things but there is a couple of problems which is happening to me

- Nvidia 3D Graphic Card
- Samsung 3D TV 8 Series
- 3D Vision from Nvidia

I've got a problem when my computer starts the stereoscopic wizzard where my 3d Tv can't be detected by my PC and the Samsung doesnt have an IR immiter to place it from the device

please someone help me it's been 2 days and i can't find an answer

thank you guys



Answer
The Samsung TV does not support nVidia's 3D Vision. Only a few computer monitors support it, because they need to run at a 120Hz refresh rate. Many HDTVs run at 120Hz but the only ones currently on the market that support 3D Vision are from Mitsubishi. Here's a list of computer monitors, Mistubishi TVs and HD projectors that support 3D Vision, from nVidia's web site:

http://www.nvidia.com/object/3d-vision-requirements.html

Sorry, but you'll have to return that TV and buy one of the supported displays to get 3D Vision to work.

how are 2012 altima HID xenon lights different from 2010 Lexus es350 hid xenon lights?




Robert


Does the Altima project it differently? I'm thinking Altima's reflected back towards the front of the car while the Lexus just projects forward.
Could I simply buy a 6500K bulb or would I need to replace the system?



Answer
I know what your talking about but this will be difficult to explain.

The Lexus ES350 has a special halo projector. Look at the front of BOTH of this picture:

http://www.autodoodad.com/images/415_LEXUS_ES350_5000K_lights_6500K_fog.jpg

http://www.caranddriver.com/var/ezwebin_site/storage/images/buyers_guide/lexus/es/2007_lexus_es350/2007_lexus_es350_short_take_road_test/2007_lexus_es350_short_take_review/2007_lexus_es350_short_take_review_2007_lexus_es350_headlight_image_001/342761-1-eng-US/2007_lexus_es350_short_take_review_2007_lexus_es350_headlight_image_0011_cd_gallery.jpg


Notice that there is a circle projector that shoots out the xenon lights.




Now compare this with the Nissan Altima headlights...

http://www.blinglightsworld.com/images/2011NISSAN.jpeg

http://www.caranddriver.com/var/ezflow_site/storage/images/news/car/09q4/2010_nissan_altima_sedan-first_drive_review/gallery/2010_nissan_altima_sedan_headlight_photo_8/2937037-1-eng-US/2010_nissan_altima_sedan_10_2_2_cd_gallery.jpg


You will notice that the halo projectors aren't there in the Altima. (the circle projector lights)

Every car has reflectors which reflect the lights towards the road for better visibility, but the Lexus ES350 (also followed in the Toyota Camry) has halo projectors which provide better visibility during the night. It slightly works with higher Kelvin than a normal headlight bulb (I think they operate at 3K).

So basically the lights of a Lexus (with special halo projectors) shoots out vs the lights of an altima reflects inside the headlights for better visibility and then shoots to the road. Although I don't know how the lights reflect in the lexus but they are much better than standard headlights.

Lexus ES350 uses 6500K Xenon, Nissan Altima uses 43 or 4900K (I think, not sure about that).

Here is a chart of xenon lights temperature:

http://image.made-in-china.com/2f0j00mMnTgBdPpokA/King-Eagle-HID-Xenon-Bulb-Color-Temperature.jpg

You need to have special halo projectors in order for it to reflect like a true Xenon.



EDIT:

Do you have the Altima?

3-D Projector Help Please?




blaze


Hello all, I am interested in purchasing a Vivitek D511 3-D "ready" projector and I was wondering if anyone knows if this will be compatible with a 3-D signal from my PS3


Answer
3D DLP projectors generally only work with Nvidia 3D Vision graphic cards that are installed in PCs. That projector is not compatible with the 3D output sent from a PS3 over an HDMI connection. In fact, that projector has no HDMI inputs, only a VGA input.

If you want a projector that is compatible with 3D from Blu-ray and PS3 games, there are not many to choose from yet. This list shows 9 projectors that natively support 3D input over HDMI 1.4a, and 7 that can support it when used with a $399 converter box made by Optoma for their projectors: http://www.3dmovielist.com/projectors.html .

3d vision technologies: types and technical differences?




ataru


the last few years saw a boom in 3d movies.
i've noticed that the new glasses for this new 3d wave are bigger and different in complexity from those i've been used to in my childhood(red and green plastic or even paper glasses)

so, technically speaking, what's this new technology behind this new 3d-wave? how's different from 1950's red-cyan technology? is possible to play this new 3d technology with a normal computer video card and a normal monitor(assuming you bought the proper glasses), or it does require something different?

i mean, if its just an upgrade, a better version of red-cyan anaglyph technology, one would just need the glasses. but i noticed, while reading a tv catalog, that some TVs have the "3d feature" while others dont. so this must be a different technology in its deep basis. right? what is?

also, i saw an advertisement on tv, a new nintendo ds in 3d, without glasses. how is that possible??? its just an hoax?? (as far as now i didnt saw one of them for real)



Answer
There are a number of glasses based 3D schemes now in use:

1: Polarizaton. The glasses use polarized light filters, with opposite polarizatons for each eye. With them, the projector alternately projects pictures for each eye, and have a mechnical filter scheme, or two separate projectors with separate polarzing filters.

2. Color bands (Dolby 3d). Separate color bands are projected for each eye, a pair of blue, a pair of red, and a pair of green. The glasses have filters whch filter out a specific color band for each eye.

1&2 are used exclusively for theatrical presentation, both becasue of the cost of projecton is high, and the cheapness of the glasses, because those can run off.

For home there is
1. Shutter glasses. In this scheme alternate images are displayed in alternate refresh frames (they are transmitted two pictures per video frame, usually half and half, and re-jiggered in the TV display processor.) The glasses use LCD shutters which alternately block the light to each eye depending on frame displayed, controlled by an IR or RF signal from the TV. Shutter glasses 3D is cheap for home TVs, but you need a more costly glasses, but those are not bound to run off.

2. Lenticular (what the DS-3D uses). In them, alternating columns of pixels are displayed for each eye, and optics applied to the display guide their light in a way as only that eye sees them. For now, only the DS-3D is the only marketed device with them, but Toshiba showed lenticular 3D TVs at CES this year.

3. Positon 3D. Not really 3D, but using position sensing devices, it can be determined where the viewer is respective to the display, and show the perspective of an object relevant to the viewer position. When the viewer moves, so does the perspective.

Where Can I Get A Projector Fixed? (in Halifax)?




Megan D


Where in Halifax can I get my projector fixed? I'm not sure why the projector's not giving any picture anymore, so I'm not %100 sure what's wrong with it, but I would imagine it blew a fuse. Where in Halifax could I get it looked at and fixed for the absolute lowest price?


Answer
It would help to know the type of projector!

Before taking for service consider whether you might not be able to fix it yourself. The troubleshooting guide at the link may help. The most likely fault is either a fuse (i.e. nothing works), the lamp has burnt out or, if the projector starts but goes off, a blocked air filter. If more serious you will need repairs ... but it may not be worth it if the projector is an older model. Minimum service charges are likely to be more than $100 just to look at it.

If you really need service try the yellow pages under electronics repair or, better, check the manual or website for the projector manufacturer and find their closest authorized service centre.

One local place that came up from a Canada411 search is Hamblen's Audio/Video Service, 6070 Almon, Halifax, NS B3K 1T8, 902-453-0400, but I know nothing about them.

where can i rent a projector and the screen for a low price here in Chicago? It's for a wedding slideshow.?




paulis





Answer
It depends on what you mean by a "slideshow." For a slide projector, slide trays, screen and even a portable cart you can get what you want at Helix on N Racine. Go to the following site then download the rental catalog then scroll down to "PRESENTATION." The rental rate is reasonable but there is a fairly large deposit required:

http://www.helixcamera.com/rental/rental.html


A desktop LCD projector will be more expensive. This place has several to choose...remember the amount of lumens determines the brightness on the screen:

http://www.avchicago.com/list.php?path=eq-e26-e41-e49&gclid=CJuR3aGv4acCFQnrKgod1g5w-A


and others that will ship and return:

Are NEC projectors good?




Arcane


I am going to buy an NEC projector. It has 2600 lumens, 2000:1 contrast ratio, 3500 hours of lamp life (5000 in eco mode). It comes with a remote, lens cap, manuals, power cables. The projector is on sell for $300. It is usually $400. Is that a bad deal? <(>.<)>


Answer
NEC is a name brand for business projectors. You don't say what resolution it is, but if it's 800x600 or better $300 is a pretty fair price. See the link for list of NEC projectors on a site with lot's of reviews and information. You can see how your proposed model stacks up.

business projector versus a home theater projector? Is there that much of a difference in black levels?




bjmarchini


I am budgeting about 500-600 for the project and about 100 for the screen. I can afford a 2000 projector.

A ViewSonic PJ506D SVGA (800x600) 4:3/16:9 2000 lumens business projector is going for 500 with a mail free screen and mount offer.

An InFocus In72 WVGA (852x480) 900 lumens home theater projector is going for about the same refurbished with no extras.

I have read that I really should get a home theater projector rather than a business projector like the 506D, but the lumens scares me.

I am projecting on an 80"screen with blinds and curtains closed. no lights. still some ambient light.

Which will be better. I am going to use it the a really nice DVD player, Wii and Home theater PC. No interest in HD DVDs for atleast 3-4 years when I will prob upgrade this anyway.



Answer
I am confuse with your question. Are you saying you can afford a $2000 projector or can't afford?

Try using a home theater projector if you can. The bussiness projectors are not meant for movies. They are meant for slide shows and a small movie clip.

Now you can get a decent Epson projector that is around $3500 Canadian dollars with a $300 rebate right now. I believe the model is the Epson 1080. Epson makes a decent projector.

http://www.epson.ca/cgi-bin/ceStore/ProductCategory.jsp?BV_UseBVCookie=yes&oid=-13702

Ofcourse you can opt to get the cheaper projector. I have personally seen the Epson 1080 and it does a great job on the big screen.

There are also some decent screen around. I think you should provision more for your screen though. Try to think $1000 for a screen. They a decent Draper screen would serve you well.

On the other hand you can also paint the wall matte white and it should work as well. You can try looking for the "goo"-this stuff is supposedly able to serve as a screen.

Question about Projector Bulbs and Warranties?




Madn3zz


Projector bulb life is rated in hours. Now most bulbs do not last more than half to 2/3rd their rated life. Can anyone explain why this happens and why the warranty does not cover it.
Better yet, can someone provide me with a solution on how to better manage this. These projector's are used in a classroom atmosphere.



Answer
I use to work for a projector company and it would be too costly to warrant all lamps to it's rated value. If this were the case, marketers would lower the rated value.

In testing, I have seen lamps last beyond 10,000 hours, even though they were rated at 4,000 hours. Of course, this is due to controlled environments and this allows a projector company to legally advertise 4,000 hours. It's an average out of a large sample. Realistically, all lamps should last beyond 1500 hours. Anything beyond that is good regardless of the rated lamp life.

One thing you should know is that there are 4 major lamp manufacturers in the world: Phoenix, Osram, Philips and Sylvania. Projector companies buy these lamps and sell them to the customer.

The manufacturing process of these high pressure arc lamps are very delicate. Any minor defect or misalignment can easily cause a lamp to have a short lamp life.

Other variables would be running lamps for a long period of time, such as 8 hours straight. A projector should be turned off and be at rest every 4 hours for optimal life. Also, most lamps and projectors have dust filter screens that require cleaning. Make sure you do this.

Some projector lamps overdrive the lamps to get the most lumens out of it. In order to overdrive a lamp, you run it at a higher voltage.

Basically, projector and lamp manufacturers are both at fault. It all depends on the design, testing and honesty of the companies.

From a customer, I know this sounds like a bunch of B.S. But, this is how it is. Unfortunately, it's legal and at the customer's expense. The only sound advice that is if your projector manufacturer has extended lamp warranties, then buy it. It's well worth it. My company had a 1 year extended lamp warranty, which meant that if the lamp expired within a year, then they would replace it at no additional costs.

Can i get my money back at fry's if I bought extended warranty?




suntanfarm


I bought a floor model of a laptop just 2 days ago and also with extended warranty since it was my first time buying a floor model because it was a laptop i was looking for and I needed it for school since my last one died. Reading reviews, fry's seems to try to squirm their way out of the agreement like saying there's moisture damage even when there isn't or replacing the item with something of lesser value so I might as well take that money and use it for other things.

I personally have no experience with Fry's because I normally go to Bestbuy but they didn't have what I needed.

Help with 720p to Epson projector?




duck_hairb


If anyone can solve this problem for me I will buy them a small horse.

I've had this Epson EMP-TW100 projector for years now and only ever used S-Video. Last month I built an HTPC with a DVI output because I was hoping to watch Blu-Ray and other HD content on my projector in its native resolution 1280x720 - nice hd widescreen.

Except I can't. I have a 780g motherboard, on board Radeon 3200 graphics with DVI output. But if I switch to 720p (I have to force it because the graphics controller software says the best the projector can do is 1280x1024) the screen flashes and the projector claims the mode is "Not Supported".

The projectors manual, btw, expressly says that this mode IS supported.

Now I have no other DVI source to test with so I can't pin the problem on either component.

I've tried altering the frequency of the video signal, no dice.

I know the graphics card, projector and cable work because I can get 1280x1024. I can zoom this image to get a 1280x720 but I lose the top and bottom of my desktop.

I have the latest Radeon drivers for the graphics card.

Any ideas? Anyone?
Thanks to Adam T for trying, but the projector is the only screen connected to the htpc - there is no monitor confusing the graphics card. The projectors native resolution is 1280x720 (it's a 3-panel LCD) which is widescreen.



Answer
I couldn't speculate as to why your projector flashes when it gets the signal from your PC. However I may have a solution for you concerning the zooming and losing part of the screen.

I'd suggest that you're having an aspect ratio issue. If I had to guess, you are probably using a non-wide screen computer monitor. Since your computer wants to display the image on your primary display (the computer monitor) correctly, the secondary monitor (your projector) is displaying the same aspect ratio as the primary display.

Here is your problem, the software automatically suggests that you use 1280x1024. This is a bad resolution to see wide-screen video because it is almost a 4:3 ratio. 720p is a 16:9 aspect ratio, but your graphics card might not want to display that either. Wide-screen computers use a 16:10 aspect ratio.

So, when you tinker with the screen resolutions I would suggest that you force the graphics driver to output a resolution at:
1280x800 or 1280x720

If you get error messages or if those options are ghosted out, I would turn off the computer and restart it with your monitor unplugged and only having your projector turned on. This may help your computer automatically make the switch for you.

Question for EPSON projector owners?!?




Bob A


Hello,

I am getting ready to buy one of the LCD projectors from EPSON, but for those of you who have the newer models of their projector line:

"What exactly does the zoom feature do?"

Now, I know that when you move the projector far from the screen, the image increases in size. When you move it closer, the image decreases in size. So, does zooming allowing you to obtain a decreased image from far away just like if the project was closer to the screen? Thanks for the clarification and please do not direct me to another source. All I want to know is if I can adjust the size of the screen when it is x amount of feet away from the screen.

Example:

When the projector is 12 feet from the screen, the size may be 70x70. Can I "zoom in" and have a 50x50 size screen from the same exact 12 feet from the screen projector distance?

Again, thank you for the knowledge and if you don't have an EPSON, still inform me the general nature of the product.



Answer
Your understanding of it is correct. The zoom lens enlarges/decreases the image size.

How much you can zoom in and out is dependant on the projector. If you had it at 12 feet and had an Epson PowerLite Home Cinema 1080 UB then you would have a range of 57" to 122" diagonal.

Check out your projector on http://www.projectorcentral.com and use their calculator to estimate the size of screen you can have when the projector is X feet away from the screen. Their calculator will also tell you an approximate brightness of the projected image (how dark you room has to be).

I have an older Epson 550, but the zoom lens is the same as the newer models. I have my projector 10 feet away from the screen and it will go up to about 96" (diagonal). I have mine at 90" though.

how good are mini projectors?




Kash J


I want to know how mini projectors perform in different lighting applications compared to the larger projectors out there. Are they as good as the larger projectors?


Answer
No they are not. mini projectors use LED technology instead of using a lamp, which is what regular projectors use. LED projectors are NOT bright at all. Plus, normal projectors have many video inputs, where LED's dont.

Technology for School?




Swista


I am a Second Grade Teacher. My school badly needs help with its technology program. It believes that having new computers is the only way to keep up with technology. There are no smartboards or projectors in the entire school (K-12) There are 2 Tv's breing shared in the elementary school. I would like to present some ideas for technology grants and money to be spent in better ways. What are some ideas? (We really don't have any cool programs either) Please help so I can have a good presentation.


Answer
A compelling model that is pretty hot now in the federal and private funding community is the use of technology to increase both student success, faculty competence, and student retention from P through 16.

So, if your elementary school picked a partner secondary school and then a partner college (4 year and/or 2 year college), you all would sit down and assemble the SMART technology and determine (based on research based best pratices and evidence) on what faculty across the different levels of schools can do to modify their curriculum so that the technology can be used in "inquiry based learning" opportunities for the students at all the levels. You would then have meaningful workshops for faculty so that the elementary school faculty could hear what secondary schools need for students to really master to do well at that level....then both elementary and secondary schools could hear what postsecondary schools say is needed of students in order for them to do well on their level. Then each levels and ask what can they do with their technology to help support the levels lower than them.

The sky's the limit with this expanded 2+2+2 model. What you proposing to do, though, is to create a seamless pipeline of relevant learning for students so they can be very competent in this technologically advanced global community.

Your tech companies in your area would support something like this and so would federal funders like the Dept of Ed and the National Science Foundation.

Hope that helps!

home theatre projector-whats the deal????




alkjdfajk


whats the big difference between a 20000 dollar projector and a 400 dollar projector is it that noticeable? and also I see a lot of LCD projectors on ebay for under 400 dollars is this for real?? i mean why wouldn't everyone buy that which can project a 100 in screen instead of an expensive lcd tv thats 26 in for the same price???? whats the catch??


Answer
A more expensive projector will get you improved resolution, brightness, contrast, sharpness and color accuracy. Cheaper projectors selling on ebay for $400 are typically business projectors and/or earlier home theater projectors with poor contrast. Addionally, bulb costs on those earlier projectors can be exceedingly high, more than the cost of a new, higher quality projector.

A business projector usually does not make a good home theater projector, for a few reasons:

1. It's designed to be used in a room that's not necessarily dark. This means it will have high brightness, but probably not a lot of contrast. This makes for a washed out picture.
2. It will not have as good quality scaler as a HT projector, since it's meant primarily to use with computers, which dont' need scalers (a scaler, which is built into all modern digital projectors, matches the resolution of the video signal with the native resolution of the projector).
3. They usually have 1024x768 resolution with a 4:3 aspect ratio. For home theater you'd want at least 1280x720 (720p) with a 16:9 aspect ratio to match HD TV.

You can get a decent 720p home theater projector for under $1,000. 1080p projectors can be had for well under $2,000. Do some research online, and don't jump on a cheap projector because it sounds like a good deal. You'll more than likely be sorry.

Whats a Good TV or Projector for Gaming and Movies?




Navi


I'm getting a PS3 soon and I already have a Wii and I also have a large collection of movies, over 450.
So which should I get? A Plasma or a LCD TV or a big 105 inch HD Projector?
I'm looking for best visual quality because I already have a surround sound system.
Also I would like to keep the price at least under 1000 dollars because I've seen some big TVs and projectors for around $400.



Answer
don't get the projector, they get ruined by games. the plasmas get good sharpness but if you leave a game or movie on pause for too long because of the way it works it leaves an imprint of that image on the screen for ages while you're watching it again. So get an LCD. We have a Panasonic Viera 32 inch, that was $1500 and it has full high definition capabilities it can handle blu-ray and all the rest of it, and it is excellent viewing quality. however i'm sure the other major brands are just as good (ie Samsung, LG, Pioneer, Sony) but DO NOT buy a cheapo one from K-mart or Big W or something, always go to places like JB HiFi for TVs because the people there know what they're talking about and no matter how much the Target workers tell you that the TV is massive with high resolution and has all the capabilities, you will still get shitty picture quality from a brand you've never heard of.

Who can give me the names of the best hd projectors under $2000?




toddrick





Answer
Depends on what you want to use it for. The best for home theatre would not be the best for business. It also depends what you mean by "hd". Assuming you mean high definition there are two levels available: 1280 x 720 pixels and 1920 x 1280 pixels.

The CHEAPEST of the 1920 x 1280 projectors lists for $4000

There are a number of excellent 1280 x 720 (or 788) projectors, including the latest LCD models from Panasonic and Sanyo (See first link for a comparative review), but both are a bit beyond your $2000 limit. The best 720p projector for the $$ is arguably the Mitsubishi 1000, currently selling for $1000 (See 2nd link for a review).

That said, have a look at current reviews and judge based on your needs / priorities. Any of the big names in projectors can be safely chosen, but you might be wise to pick a brand with a good local or reputable on-line dealer. Some brands to consider include Optoma, Mitsubishi, InFocus, Panasonic, Sanyo ...

Hope this helps.

how can i maximize my bulb life for my projector?




John D


How could i maximize bulb life for my porjector. recently it went out. it went out prematurely. is their any cause for this. not well ventalation, i also a air vent right above it that blows out air. hot air this season. and could that make that much of a difference on how long it lasts. its always on economy. also, would having the projector turned on and off more often cause the lamp to go out


Answer
1. You should move your projector away from the vent, first thing. The dust and particles that come from the vent can do some real damage to your projector.

2. Be sure not to unplug your projector or shut it down completely before the fan has run for several minutes and turned itself off.

3. If your projector has a filter, (newer projectors may not have filters, but most older models do) be sure to clean it regularly.

Lamp life specifications can be a little deceiving. If your projector manufacturer says the lamp is supposed to last 4000 hours, its actually specifying a half life. Your lamp may last longer than that, but it should not fail completely before that time. But either way, your lamp will be less bright at 2000 hours than it was when you first purchased it. And it will be less bright at 4000 than it was at 2000. Manufacturer lamp warranties are typically only good for the first 90 days of ownership, (though some are now as long as a year), but extended lamp warranties can often be purchased for under $100 and may be worth the investment.

Someone mentioned that most projectors have fans that keep running once the projector has been shut down, that is true as long as you leave the projector plugged in. Newer projectors (those released in the last year or so) will include a battery that will run the fan even after it is unplugged, but if your projector is older than that, you won't have that feature.

What is the best home theater projector available for less than $6000?




drjay71


I would like the best picture quality available.


Answer
There are several projectors available in this ($0 - $6000.00) category. In fact as technology has improved, pictures have gotten better and cost has come down to where most folks can actually afford to enjoy LARGE Screen movies in their own home!

*There are 3 projector technologies that are currently in use in the home entertainment industry: LCD (Liquid Crystal Display), DLP (Digital Light Processing) and LCoS (Liquid Crystal on Silicon.)

***LCD is the most mature of the three types in terms of age and number of units produced. It claims it's roots in the commercial and House of Worship (HoW) arena. Because of this, there are more "high brightness" LCD projectors than any other type. If you're theater is situated in a daylight room with little in the way of light control, LCD may be an excellent choice. Their picture quality has also improved over the years to the point where some brands are considered fairly stiff competition for some of the DLP and LCoS offerings. The best LCD projectors will most certainly look much better than their DLP or LCoS counterparts in this price range if the room's light can not be properly controlled.

Answer a) Ep son's Pro-Cinema series LCD projectors are a favorite in the daylight or medium lit room category and worth a serious LOOK!

**DLP is the technology that Texas Instruments (TI) developed to improve black levels and color accuracy. Over 6000 commercial DLP Cinemas were installed as of 2008 (currently searching for an update to this count) and they hold the lions share of all new Cinema installations world wide due to their VERY HIGH contrast ratio and resolution. The first company to partner with TI and offer a DLP Projector was the Kennesaw, GA manufacturer, ******Digital Projections Inc. (DPI) who is the ONLY projector manufacturer to ever win an EMMY Award for a projector (actually two Emmy's were awarded to DPI in 1998 for Outstanding Achievement in Engineering development.) By the way, DPI offered 18 new 3-D projectors at InfoCom 2010.

Pricing for DPI projectors starts nearer to the $9k mark than $6k but worth a look if you inherit your rich uncle's change purse. Outstanding picture quality! State of the Art. If you can afford it, DPI is the 800lb Gorilla in the room of DLP Projection!

Answer b) Digital Projection's DLP projectors - Worth a Really $erious LOOK if you can afford it!

*****Mitsubishi may be the best known and most sought after manufacturer of DLP TVs and projectors. They offer both front projection (on the ceiling) and rear projection (table top TVs.) Their table top line has recently become VERY, VERY popular due to their outstanding picture quality, *3-D capability (since 2007!) and size vs. price. If 82" is large enough for your Home Theater or Family Room (and that IS really pretty BIG!) then you should consider these products. No "DARK ROOM" needed.

Although some of them ARE wall mountable, they may be a little too deep for some folks taste. That being said, we've seen many of them mounted in built-in "cabinet nooks" and above fireplaces and their very thin bezel looks fantastic when installed this way. The Mitsubishi front projectors have been very highly reviewed in the trade and on-line review magazines and have fantastic pictures. These projectors and TVs will easily fit within your requested price cap with room to spare for all the add-ons you will probably need to finish off your new Man (or Woman)-Cave.

A word about 3-D: *3-D is really cool but if 3-Dimensional movies really are YOUR thing, make sure your TV or projection screen is plenty Big enough. Anything smaller than (approx) 72" diagonal is going to leave most of you wanting more. If you don't believe me, take a look at the closest Big Box Store that demonstrates 3-D. There's nothing worse than a 3-D animated graphic or effect that becomes 2-D at the edges because your "Field of View" is larger than the screen! YUK! You either need to scoot up really close (for 50"-65" sets) or be sure that the screen you purchase is taller than your *3-D glasses lens (field of view) so you can sit in your favorite chair 10-12 feet away.

Answer c) Mitsubishi Table Top DLP TVs - If 82" is big enough and you don't have to hang it on the wall, these TVs are outstanding in any light condition and the Price is Right. They have several 3-D models. They are worth a Serious LOOK!

Answer d) Mistubishi's front projectors (either series) are a great value for light controlled rooms with fantastic color pallet and contrast ratio. Better than most LCD given you have some sort of light control. Dark Room is BEST! Worth a LOOK!

You may want to consider the Optoma brand as well if front projection DLP is what you need. They have been coming on strong for the last couple of years and have proven to be incredibly competitive to Mitsubishi! Very quiet and easy to place in an odd shaped room with lens shift features.

Answer e) Optoma projectors - The higher end of the Op

If you display a projector at its max screen size, is the picture quality degraded?

That projector claims a max screen size of 300", which is 25 feet. If I were to display it like that, and sit the appropriate distance away, would it still be a clear 1080i picture?



Answer
It will vary depending on several factors including whether the projector manufacturer chooses to use a realistic number or not. More often than not the maximum screen size typically specified by projector manufacturers will greatly compromise video image quality.

Using the standard zoom lens on Sonyâs mid-to-lower-midrange priced VPL-VW60 1080p projector requires the projector to be placed at a âthrow distanceâ ranging from a minimum of 369 inches (30 feet 9 inches) to a maximum of 631 inches (52 feet 7 inches) to produce a full 300-inch diagonal, 16:9 projected image. For example even if you choose the maximum projector zoom setting of approximately 1.7Ã in order to obtain the shortest throw distance of 369 inches (and thereby providing us a look at the best-case, highest illuminance scenario,) you will still end-up experiencing very poor off-axis viewing angles, i.e., a very small viewing sweet spot, as well as poor screenâand therefore imageâuniformity resulting from a necessity to use the highest-gain screens available. Alternately you can use a comparatively lower-gain 300-inch screen (e.g. under 1.3 to 1.4 thereby improving the screen uniformity and viewing angle a little,) and experience an unacceptably dim* (approx. 1 to 2 fL!), washed-out, low-contrast picture. Of course all of this assumes that you would setup, configure and operate the VPL-VW60 projector properly. So in a nutshell... yes picture quality would be noticeably âdegraded.â

You would also have to take into consideration your optimumâor roughly minimumâviewing distance, which will be approximately 40 feet, give or take, for 1080p video content displayed on a 300-inch screen. To put it quite simply Sonyâs maximum specified screen size is not realistic even if one were to push everything to the limit thereby greatly compromising picture fidelity and/or your viewing experience.

Even though the projection calculators can provide you with a reasonably accurate approximation there should be no doubt that Sonyâs VPL-VW60 projector will be grossly underpowered with any normal gain projection screen larger than 108 inches or so even in a very, very dark viewing environment using the best projection screens available.

*(Note: the target white screen illuminance for professional âdigital cinemaâ applications, as recommended by SMPTE 431-1, is 14 fL or 48 cd/m² = 48 nits ±7% as measured at the center of the screen and not less than 80% of the center value at the corners and sides. This specification also applies equally well for home theater applications.)
