How much is an average video projector and is it worth it?




~glory


I'd love to be able to project movies and television onto a bare wall I have in my bedroom, but I've got a couple questions:

1) What's the general cost associated with a video projector?

2) Is the picture worth it? i.e. will I notice a difference by using a projector instead of a TV?

3) Can the projector be used to project DVDs as well as cable programming?

4) Is this stuff easy to install? I have a huuuuge vaulted wall, which is why I have a sudden interest in this idea, but installation needs to be simple - i.e. mount the projector on the wall and let it roll ;)

Thanks guys!



Answer
I found a really good 720p projector for $850 on amazon.com (Sony VPL-AW10 or it's higher end brother VPL-AW15). They can accept (and display) 1080p signals, even at 24 frames per second.

I wouldn't show it on the wall - get a screen. A cheap one is $60, but you can pay a whole lot more. Some screens are more reflective than others (result is it being brighter).

Look at bulb costs too. Bulbs can cost a few hundred dollars and will only last 3000-5000 hours as opposed to 60,000 hours lifetime of other TVs.

The picture will be better in the dark, and with everything set up it's like going to the movies but without leaving your house. I don't have shades where my projector is setup and I found that in the daytime or at night with the overhead room lights, I can't calibrate it for contrast and brightness. There's only one correct setting for those adjustments and I can't get it with the lights on or in the daytime. I can still watch the TV with the color temperature up high and the brightness cranked up though. It is not bad. It's very good in the dark and the calibration is correct (which I'm happy about).

My projector has component input, hdmi input, composite input, and VGA input so you can hook up whatever you want to it including DVD and cable programming.

It's easy to install if you get the right tools and the right mouting fixtures. Sony was out of their minds when I looked at the price of the ceiling mount recommended in the user manual for the projector - it costs $650, but the projector cost $850. I ended up finding a universal mount on Amazon.com for $60 with $40 rebate (which I haven't cashed in yet). It took a couple hours to install it and I had to do it a few times with the universal mount to make sure that I had the mount right over the center of gravity of the unit.

Caution: If you hang a simple cheaper projector from a high ceiling and the projector has no optical lens adjustment (which are sometimes availabe but not on my projector) the image will "keystone" on the screen where the image on the screen starts to look like a trapezoid. There are electrical compensations for this to reverse the effect, but you loose 1:1 pixel correspondecse with the input signal. In my case, it's not extreme since I don't have high ceilings. You could mount the projector on the far wall, but the image would be large. The specifications show how far away you can be (within a range) for a specific screen size. The projectors have zoom and focus adjustments.

There are lots of other projector brands and models - even 1080p ones.

Good luck

best home theater projector for a home bar room?




kakountry


The room is in the basement but, I may have the lights on sometimes..


Answer
It is difficult to recommend a specific model without more idea of price range, details of the location where it will be used, and viewing preferences, here are some specs. to look for.

The primary requirement is a brighter projector than one designed exclusively for home theatre use ... say 2000-2500 lumens.

Most do have it, but you should also ensure there is a low light setting for when you would use in the dark ... this extends lamp life.

Depending on the priority you place on home theatre use under controlled (i.e. none) light conditions "contrast ratio" may be more or less important. For use in a lighted room anything over 1000:1 would be fine, but if you wish to use as a home theatre projector look for at least 2000:1 (higher is better).

There are many other specs to consider. The most important is "resolution" -- the number of pixels that make up the image -- if you don't intend to watch HDTV you could get by with a 480 x 854 (vertical x horizontal resolution) projector, but otherwise you should look for at least a 720 x 1280 model. If money is not an object consider a true HD projector (1080 x 1920) ... although note that all I am aware of under $20K or so are lower brightness projectors than you need.

Another important consideration is "aspect ratio". These days most recommendations will be for a 16:9 (widescreen) projector; and this is valid if you intend to watch mainly HDTV (e.g. sports) and widescreen movies. However, if you intend to watch old movies (4:3 aspect ratio) consider that 4:3 as a subset of a 16:9 image (there will be black bars on each side) makes for a small picture. If you note that even on a 16:9 (1.78:1) screen wider aspect ratio movies (1.85:1 to 2.40:1) will have black bars on the top and bottom, black bars will be a fact of life. So consider that a 4:3 aspect ratio projector will provide a huge picture for 4:3 material and widescreen will show as a subset the full width of the 4:3 screen but with variable amounts of black bar above and below. (Put simply a 4:3 image on a 16:9 screen is small, while 16:9 (and wider) and 4:3 images on a 4:3 display are all large). Worth considering.

Other specs to consider:
- "fan noise" (anything under 32 db should be OK in a bar room, but for quiet viewing look for something under 28 db)
- "lens zoom ratio" (at least 1.3:1, but 1.5:1 or more provides greater flexibility)
- "weight" and "size" (something in the 8-12 lb level would be good, but unless space is a big issue this isn't a major consideration)
- If a DLP (digital light processor) based projector the "color wheel rotation speed" should be at least 4X, and preferably 5 or more). If an LCD this is not relevant.
- The availability of "lens shift" (ability to shift the picture vertically (or horizontally) relative to the position of the projector) is desirable to make mounting easier. ("Keystone" adjustment may be provided but should be avoided since it degrades the picture).
- cooling air filtration: THIS IS PARTICULARLY IMPORTANT IF THE PROJECTOR WILL BE USED IN A SMOKING ENVIRONMENT. All projectors use a fan to push air past the bulb to cool it. Most have a removable/replaceable air filter. A few have a sealed system. If everything else meets your needs, a sealed system is a desirable feature. Failing that look for an easily accessible filter (e.g. you don't have to remove the projector from a ceiling mount to get at it).

OK ... how about a few possibilities (not intended to imply there are not other good choices, particulalrly if you settle for less brightness):

$1000 range: Sharp XR-10

$2-3000: Panasonic PTAX100U (16:9)

$3-5000: Canon SX-60 (4:3)

I personally have the Canon SX-60 and while you can get a less expensive projector it would work well for your purpose.

projector screen size?




krazykid12


how big do you thing my projector display would be if it was 11ft away from the wall?


Answer
You don't specify the projector, and since the lens (and its zoom setting) determines image size no-one can answer your question with any accuracy.

That said, most projectors will give an image of at least 90" at that distance. The easiest way to find out is to look in the instruction manual, and the next easiest is to set up the projector and measure the image size.

If you want to know what the 'right' size image is for a viewing distance of 11 ft see the link.

Projector help for home theater.?




enels4


I was thinking of getting a projector for my home theater and i was wondering, which aspects do i need? and which one should i get? Please try and remember that i am on a budget.

I was thinking of the InFocus IN2102EP. Does this look good for my needs? Is there anything i am overlooking? Thanks for your help.



Answer
A projector is a great way to go ... I'd never go back to a TV for watching movies or HDTV programming.

For a HT the needs are a bit different than for a classroom or business setting. You need a projector with as high resolution as possible, good video processing, high contrast, quiet fan, capability to connect DVI or HDMI inputs, and typically (because of the darker room easily achievable) don't need high lamp brightness (e.g 1500 lumens is enough). It's also desirable -- but not essential -- to have a wide zoom lens ratio and lens offset capability to facilitate installation. Size, type, etc are secondary.

The InFocus you suggest (see link for specs) is designed for classroom use. It's not a bad choice, but the 2000:1 contrast ratio is on the lower end of the recommended range for HT use. The 800x600 (SVGA) native resolution is again on the lower end of acceptable for HT use. The real weakness is the lack of any form of digital input (although component video via a VGA adapter is an acceptable alternative given the resolution capability). That said, it's about as good as you are going to get for the price (and better than many alternatives) and InFocus are a good manufacturer.

See the links for reviews and lots of info on projectors. Worth reading.

Hope that helps.

Can a projector make this size of image? Also, HD or SD?




Johnny


I want to use a projector instead of a TV, because the only available space is above a radiator and I'd rather put a projector screen there than any electronics like the xbox 360.

The length of my room from wall to wall (from projector to screen) is around 9.5 feet. A bit less when you consider that the projector itself would probably be around a foot long on its own, so it might be around 8.5 feet from projector to screen.

I only really have space to fit around a 50-54 inch 16:9 screen including any borders though.

Can projectors make that kind of size from that kind of distance?

Would I notice the benefit of 720p in these circumstances or should I just stick to 800 x 600?



Answer
Ok, you asked several questions in one! The other answers are correct, but I'll try and make this specific and comprehensive!

First, what projector do you have? If you let me know, I can tell you what the throw distance would be to get a 54 inch image. Typically speaking, you can get a 54 inch image with about a 6 or 7 foot throw length, depending on your projector. You definitely will be able to get a 54 inch image with 8-9 feet of throw space. Check out the calculator in the source list for exact ranges of your particluar projector.

Your second question is would you notice a benefit with a 720p projector over a 800X600 native resolution. My answer is WITH OUT A DOUBT. I actually just compared a Toshiba DLP-S25U projector with a native resolution of 800X600 to a Panasonic AX200U projector with a native resolution of 720p. The difference was incredible!

A couple of issues with projectors, as well as HD TV's:

First, there's a huge difference between 720p with a 1200:1 contrast ratio, and a 720p with a 6000:1 contrast ratio. The reason for this is because the picture sharpness and detail is all in the ability of the projector or TV to display different amounts of shading. The contrast ratio is how many shades of grey are between white and black. To get the best HD picture, you need a contrast ratio of at least 5000 or higher. Newest TV's/projectors now are 10,000-15,000:1 ratios!

Keep in mind that 720p means a native resolution of 1280X720. This means there are 60% more lines of resolution over 800X600 picture. That is truly significant! Is it life and death to upgrade? No. But if you see what 720p looks like, you won't be able to go back to 800X600!

As someone who has purchases many projectors and used them from my own home theater, to large auditorium settings, I would recommend you get a projector that has a 1280X720 native resolution, also known as 720p. Don't be fulled by projectors saying they are HD but have a native resolution of 1024X768. They will say they are 720p/1080i capable, but what it means is they can receive an input at that resolution, not that they can project at that resolution.

I would also want a projector with at least a 2500:1 contrast ratio, and would prefer 6000:1 or more. If you want to truly see the ability of HD, then you need the high contrast ratio.

Lastly, get a projector with between 1000 and 2000 lumens. I wouldn't go under 1000 in case you need it in a bigger setting at some point. Anything over 2000 would totally wash out 54 inch image and not make a good picture. I personally can recommend the Panasonic AX200U projector. It does an amazing job. It's 2000 lumens on full bright, but has an economy mode which takes it down to 1700. The contrast ratio is 6000:1, and it has a zoom lense of 2x, which is far superior to almost any other projector! Basically, from 8 ft away, you can have an image that is 40-80 inches, or anywhere between.

You can buy a brand new one on Ebay for $1250. I have used it in a small setting (about 60 inch screen), and just used it to broadcast the BCS National Title Game earlier this month on a 138 inch screen! It is a phenomenal projector for the price! Good luck!

Viewsonic Pj503d zoom help?

Q. Hi there guys,

Today I bought one of these Viewsonic projectors, and realised after I had set it up where my old projector was (which could zoom in and out), the image was slightly too big. This is quite annoying as it was just perfect before, and moving the projector or the screen is really not an option.

Are there any suggestions to what I could do? The specs say that it has "digital zoom", and I just need to zoom out by about 10 inches so it fits correctly.

Cheers, James


Answer
I don't think it really has a digital zoom. It says it does on projectorcentral but I downloaded the user guide and there is no mention of it. I also read several reviews that say it has no zoom at all. If that's the case, you would obviously have to move the projector or buy an after market lens that would probably cost as much as the projector.
