How can some projectors be HD 1080 and have a resloution of 800 X 600?

best 720p projector for gaming image

Lipiew

I'm looking for a projector for my x-box 360 and I want to get the true HD picture I saw this very well priced Infocus IN1 DLP gaming projector that was HD but low resolution. Whats the point of having HD if it can't get a high resolution? Then it's not really HD or is it in some why i'm missing?

Answer
I doubt the 800x600 projector is sold as an HD projector ... since it really isn't. But it can accept an HD signal.

Any digital display (flatpanel or projector) has two resolutions that matter: the native resolution -- which is what all images will be displayed at -- and the accepted input resolutions -- what signals can be accepted and deinterlaced/scaled to fit the display.

It is normal these days for a projector -- one with say a 800x600 native resolution -- to accept the common standard signals (including 4801, 480p, 720p and 1080i). Note that this includes HD resolutions.

However, the image you see isn't actually an HD image unless it can be displayed at 720 pixels or more ... which it can't on a 600 pixel (vertical) display. That said, it does accept an HD signal and does give an image -- which in many cases will look darned good.

It might sound like fraud, but in concept it isn't any different than a 1080i signal displayed on a 1366x768 (720p) display ... the input resolution is scaled down to fit the available pixels.

Is the picture on an 800x600 display as good as on a 1280x720 display? Maybe not, but at normal viewing distances you won't see a difference due to resolution differences (although there may be differences due to the quality of the lens or video processing -- and they could even favour the 800x600 model!).

But you probably pay a fair bit less for the 800x600 model. As with most things, you get what you pay for. The trick is to know what matters and what doesn't. In this case, the lower price may be worth the slightly lower resolution ... or it may not ... that would be your decision.

I hope that helps.

How cheap can i get a decent projector and screen for my room?

iaskquesti

I am 14 and i want to purchase a projector and a screen to watch dvds and play video games on. i have a large bedroom and i can get it very dark. the picture does not have to be amazing.

Answer
Unless you are willing/able to pay $300 or so every 3000 hrs of use to replace the lamp I'd forget a projector. However, if you still want one you can probably find one with a less than HD image for $300-$400. A 720p model (HD) will be in the $600-$800 range.

What sound system, lasers ,lighting and big screen projectors do i need?

gold digge

I want to start up a dance events in venues that can take 600 people . I know very little about the kind of kit i would need and don't want it looking and sounding cheap. I have between £10,000 and £20,000 to spend. What do i need and is this enough cash ? It have to be portable .

Answer
Hi, Gold Digger,

I'm in the USA, but I'll try to help you (I'll use the American $, but I'll try to do a basic conversion at the end.)

The venue differs based on size of the venue itself (floor space and design.) If it's a square room / hall with high ceilings, you can make due with a few (2-5) kWatts of sound. If there's a weird design and you have to pump out to each nook, you might have to add more speakers at a lower wattage. You're looking to spend about $3000 for 6-8 speakers, depending on the configuration, plus another $1500 on amps, and another $1000 on cables and "road gear" (like portable rack units, etc...) That's about $5500 for audio.

Lighting can be simple or very complex. Depending on the venue, you can spend $1500 for a very sophisticated show [with maybe 6 lights,] or you can spend $10000 and have a gaudy-as-hell production. Let's say lights will cost about $5000, with trusses, cables, and controllers costing another $2500. That's about $7500 for lights.

Lasers are interesting. If they are featured as an effect (ie: behind the DJ,) you might be able to get away with only having one, and spending $200 on it. Add a smoke machine / fogger, and the whole thing costs $300. On the other hand, if you want to go crazy, you can easily spend $100,000 or more for a "white" laser and beam splitter that will handle things like animation, etc. Let's say you go with something a bit more simple, and spend $2000 on lasers.

Projectors can also get costly. If it's a small venue, dark, and cozy, you can get away with a $1500 home theater projector. If the venue has a flat white wall, you don't even need a screen. If, on the other hand, your're outside, or the screen needs to be a few dozen meters tall, you'll likely need a professional or industrial projector. Those can cost upwards of $10000 each. Ideally, you might try two 6000 lumen projectors at $6000 each, and no screens (or screens made of bolts of white fabric [Silver Lycra / Spandex acrually works incredibly well for this] that you make yourself on a wood / PVC frame that cost almost nothing.) That would be $12000.

So, let's say you go with the audio configuration I mentioned, that's $5500, Lights are $7500, $2000 for lasers, and $12000 for video projectors, you're looking at $27000 American. That's about £17000. Well within your price range.

Factor in more for a video SOURCE (ie: DVD player, cabling, distribution amplifiers, etc...) and you're still well within your limits. You can add or remove more "effects" as you see fit.

For example, you can get more speakers at lower watts for a better sound quality. Or, you could add more lighting or laser effects. You may also want to stock up on replacement bulbs for the projectors (which aren't cheap, by the way.)

Hope that helps!

What is better an LCD projector or a DLP projector if there are more types and they are better please tell me.

best jvc projector reviews image

Answer
There is no easy way to answer the question. "Better" must be considered in context (like price, use (business or home), room size, portability, personal taste) ... and you didn't give any.

Technically, CRT projectors are recognized as giving (probably) the best picture, BUT they are huge, heavy, expensive and relatively low light output.

DLP and LCD are the most common types of projectors for home and business use. See the link for a good overview of pros and cons. BTW "Earth: The ...." response is a good overview BUT he has it backwards about the inter pixel spacing of DLP and LCD. LCD is generally MORE prone to "screen door effect" (with the exception of the Panasonic models that apply special techniques) than DLP. On the other hand single chip DLP projectors are more prone to causing "RBE" (rainbow effect) in suceptible viewers.

Single panel DLP projectors tend to be less expensive than LCD (which need 3 LCD panels to work), but often have less mounting flexibility because they don't have lens offset capability and (often) narrower lens zoom capacity.

Note, there are 4 generations of DLP chip (the latest is the Darkchip 4) and also projectors that employ either 1 chip or 3. Later generations of chip and the 3 chip models are superior. In the case of the 3 chip models you are looking at prices over $10,000 (sometimes $30,000 or more).

Note, while by no means always true, there can be fairly major differences between home theatre and business projectors (LCD and DLP models are available in either use category). Business projectors are often the least expensive models, but may be (in general) characterized as high brightness (often well over 1000 lumens), low contrast (typically under 1000:1), have poor video processing, are readily portable, higher fan noise and often lower resolution than home theatre projectors.

The last type of projector, LCOS (Liquid Crystal on Silicon) is often considered superior to either single chip DLP or 3 panel LCD. But until recently LCOS (Called D-ILA by JVC, LCOS by Canon and SXRD by Sony) was characterized as most filmlike (least intepixel grid (93% fill factor)), brilliant colours, but relatively low contrast ratio (and inferior blacks to DLP). Recent Sony and JVC home theatre projectors have improved contrast ratios (>15,000:1), although blacks are still best on a DLP (or CRT) projector. They are also more expensive than 3 panel LCD or 1 chip DLP models at the same resolution class. See the 2nd link for a review of the latest JVC.

Note that, while not a practical home theatre projector, Sony make $100,000+ SXRD projectors capable of 4K resolution (i.e. 2160p). 3rd link

So .. bottom line ... the sentimental choice for "best" projector is a CRT model, but practically speaking the 3 chip DLP designs are the ultimate home theatre projector (See one model reviewed at the last link) and the Sony SXRD 4K models are the ultimate format for the professional user.

For the "normal consumer" the latest LCOS models form Sony or JVC are arguably the best overall. BUT all projectors have pros and cons that might make one type/model rise to the top for a particular user.

Hope that helps.

how and where to pick a cheap projector?

best projector lens shift image

Roberto

i want a projector that its worth it but at the same time economic, i want it for a standard not so bright room, and I be using it as a home theater projector.
So what some considerations that i have to keep in mind, and where can i get these things?
thanks for your help xD
btw when i say cheap im thinking about 200ish more or less, although idk if its good enough

Answer
Projectors are the best way to get a big image, but they are not for everyone.

The lowest price you are likely to find for a reasonable quality projector suitable for home theater use is about $500. You may find a used one or a end of line or refurbished one for a bit less, but realistically expect to pay $500+. The lamp alone usually costs $300 or more and must be replaced every 3000 hrs or so (so be careful with used projectors .. the lamp may be almost dead).

In terms of what to look for ... resolution (look for 720p or better e.g. 1024x768, 1280x720) and contrast ratio (i.e. at least 2000:1). Most inexpensive projectors will be lower resolution and have low contrast ratio (e.g. 4-600:1). You can probably live with lower resolution (if you keep image size under 70-90"), but low contrast means a washed out picture. Better projectors have dynamic CR's over 50,000:1.

Brightness is another critieria that matters, but since you get the best image in a dark room, anything over 1000 ANSI lumens is plenty.

A wide range (e/g/ 1.7:1+) zoom lens and lens shift is nice, but adds significantly to cost.

Difference betweem a Home Projecter and a Data Proector?

ankit navl

Guys, 2 projector from the same brand and same specifications are priced differently because one is a data projector and other is a home projector. Why so, what is the difference. Now for example Benq MP 611C and Benq W100, both are priced very differently. Please explain.

Answer
There are different requirements for a business and video / home theatre projector. The latter is more demanding in a number of ways -- particulalry re. resolution, expected colour accuracy, fan noise level, and contrast ratio -- and delivering this can result in higher costs (and a higher price).

But let's look at your example. The specs are similar in many respects, but are far from the same.

Both are DLP based (although the 7 segement color wheel on the W100 (vs 5 on the 611C) may be indicative of better colour performance, and the faster spin rate is less likely to lead to artifacts (Rainbow effect). Fan noise is very similar, at least in eco mode (24 db vs 25 db). Weight and size are similar. Neither have lens shift, and lens appear comparable.

But bigger differences exist in resolution and aspect ratio (4:3, 800x600 for the 611c vs 16:9, 854x480 for the 100). Contrast ratio is marginally, but perhaps significantly, higher (2500:1 vs 2000:1) but brightness is much lower (1300 vs 2100 (the latter is typical of business projectors that must be able to work in a fairly bright room)) on the 100 vs the 611c.

The two models are plainly aimed at two separate markets, but I agree there is little to justify the apparent price difference (MSLP of $750 vs $1200), but the current dealer prices (See links below and follow the "current dealer prices" link on each page) are almost identical $586 vs $595 suggesting the marketplace agrees with you.

It might also be worth considering that price of projectors (particularly home theatre models) has been decreasing quickly in the last year, therefore the Feb 2007 shipping date for the 611c (MSRP $749, business model) and the July 2006 shipping date for the 100 (MSRP $1199, HT model) may be at least partially responsible for the apparent price difference.

Finally, while maybe not the case here, in general manufacturers will anticipate that consumers will be willing to pay a premium for relatively small feature differences. This is commonly seen in many areas (e.g. cars, cameras, stereo equipment (e.g. A/V receivers)). A base model will be one price and the next model up will be significantly more expensive because of some attractive feature that doesn't actually justify the price differential.

Hope this helps.

What do I need to build a home theater?

best projector brand for home theater image

jenavieve

My brother's moving out and we're going to have an extra room, I'd like to turn it into a home theater. I mean, I know I need a projector and a screen, but do I need speakers? Which brand of projector/ other supplies should i get?

Answer
That depends on what you want. Also, how big is this room? My HT is 19ft x 27ft and I use a projector with a 12ft 2.4:1 screen. If your room is really small it may make more sense to use a flat panel TV. Also if there are any windows that can not be completely blacked out, a projector may not be the best solution.

For audio you need at a minimum an AVR (Audio Video Receiver) and speakers. Ideally you will also have some sort of subwoofer. How big a sound system you need depends on your room size and your taste. Personally I like overkill, the audio system in my HT could fill a full size commercial cinema but I have it packed into an eleven seat HT. You probably don't need that kind of overkill.

Stay away from the so called HTiB systems. These "Theatre in a Box" systems are of poor quality and have very little or no flexibility. If one part fails you throw the entire thing away.

If you could update your question with information about your room and if you just want adequate sound to hear the dialog or if you want a true big cinema experience maybe we can suggest some specific ideas for a system.

What is a good home theater sound system for a low price?

bmskeet

I just recently purchased a home theater projector and screen and am looking for a good home theater sound system to go with it. I don't know much about them so i'm looking for some help.
I would like something that supports HD 1080. I will be using it to watch DVD's as well as DirecTV and XBOX.
Any help would be appreciated. Thanks

Answer
A budget would be helpful, when you say low price that could mean anything. Thousands for a system is low price as its endless what you can spend. We see allot people in these forums want a whole surround system for few hundred which is just not at all realistic, cant even buy a receiver for that much that's going to be any good.

First thing is there are many really cheaply made and poor sounding low priced systems on the market today so you have to be very careful if "low price' and tight budget is a concern. Not only do "all" of these cheap systems sound bad, when they break (and they will) it will cost more to repair them than what they cost new. So you'll end up either trying to bastardize the system to try and get it to work or end up having to buy a whole new system.

Do not buy any of these "Pre-packaged' systems they all use really poorly made speakers, and equipment that wont last and will break.

Your best to get a decent system one that will be somewhat reliable and even sound good, is to custom design it by buying separate speakers from manufactures that only specialize in making speakers and a receiver from a good name brand and preferably one that used better parts internally.

Paradigm, Energy, make some nice sounding and built budget speakers, and Marantz, Denon, and my favorite (but more expensive) NAD which all use high quality parts.

You have to be a bit selective with some of which model Marantz and Denon models as not all use discreet output stages and better internal parts. Look for low Impedance drive capability as this will indicate they are using better parts. What this means is when it gets loud and requires more current from the amplifier to handle these high demands it will be able to do so better with out running out of power quickly, and sending a distorted signal to the speakers and either damaging the speakers or amplifier. Its always a good idea to more power than you will ever use so the amplifier is never running close to its maximum output capabilities.

Your always better off saving up as much money as you can to get something better, and if your really wanting something good you will want to visit your local independent high end audio video store as they carry the better brands of speakers and equipment and the salesmen at these stores have many years experience designing and installing high quality systems.

The chain stores don't have a clue what they are doing, and 98% of the equipment they carry is low end anyway. The chances of putting together a good system from one of these stores is slim to none.
