    As I try to convince my wife on a large screen TV, I continually convince myself that a projector is a better way to go. But I have some questions...

    First my thoughts, I am looking to setup a DVD (only) 16:9 HT. I am not looking for HDTV at this time and would like to buy (used if possible) a projector to use with my existing equipment. I'm trying to keep it cheap (price wise) and enjoy the big screen.

    Can you connect a DVD player directly to the projector (and reciever) to play movies or is (are?) additional equipment required?

    What projector resolution is equivalent to progressive DVD output(720P?) or what is the minimum projector resolution required to play maximum DVD resolutions?

    I have an old roll-up "3M Wall Screen", 68"X68", is this an acceptable screen if I mask it to 16:9, roughly a 64"X36" screen?

    How far would the projector need to be from the screen?

    How about the viewer?

    I will be able to control ALL light in the viewing area, what is an acceptable minimum contrast level?

    What other basic info do I need?

    So what is the least expensive projector to meet my simple demands?

    Thanks for getting me started down the path...

    Yes, you can connect a DVD player directly to most projectors. Some business type projectors have BNC type connectors, but you can get BNC to RCA connectors for a few dollars.

    DVD's output 720x480 resolution, with non-square pixels. When you convert that to square pixels, you get a minimum required resolution of 854x480.

    That screen is acceptable, but you'll probably have much better luck with a 5' x 10' parkland plastic screen (

    Dan:
    Some of the current "hot" projectors for economical HT use include :
    Plus Piano Avanti HE-3200 (which will not start shipping until August):

    And the HP xb31:

    Don't be scared off by the prices indicated on those links; the actual internet price will typically be $500 or more lower than MSRP.
    Both of the above projectors are one-chip DLP-based. These kind of projectors provide generally good contrast ratio and relatively low "screendoor" effect. However, some people will detect the so-called "rainbow" effect in white areas of the projected image due to the internal spinning color wheel which is required to produce color images from the one DLP chip. (A three-chip DLP projector, like those found in commercial theaters, don't have to worry with spinning color wheels, but they're currently too expensive for HT use.)
    A low cost alternative would be a 3-chip LCD based projector.
    The much-hyped 16:9 based Panasonic AE-100 is an example of that kind of projector; but many are finding that it has too many limitations to be enjoyable on a long-term basis. Plus, Panasonic is now indicating that it may not be shipped in quantity to the U.S.
    A better alternative might be the Panasonic PT-LC55U:

    You can purchase a FL-D lens filter at any camera store that will both "punch-up" the contrast ratio on this projector, while simultanously reducing the "screendoor" effect. Such a filter typically costs less than $40.00.
    Here's some articles to read to get you started over at projectorcentral.com:
    LCD vs. DLP:

    Hope this helps!

    Thanks all for the help.

    Looks like I have some reading to do.

    Joseph - Thanks for the links. These projectors still seem pricey to match up with a $200 progessive DVD. Is there a projector that can handle 720P, 16:9 on a real budget(Not considering used at this time)? Future upgradeability is not a concern. I'm looking for a good picture without the need to make adjustments all the time.

    Maybe this doesn't exist yet, I'm hoping that prices have started to go down on projectors.

    Thanks again for the help

    Many projectors can handle 720p input. However, fewer of the lower cost projectors can output 720p, which require a native resolution of 1280x720 or higher.

    The cheapest is probably the Sony VPL-VW10HT (1366x768 native res) for about $3600. However, it doesn't use MLA technology, so if you're sensitive to screen door, it might bother you. The contrast is also not the best on it. The second cheapest is probably the Sanyo PLV-60HT which also has the same resolution and cost just under $4000.

    The FL-D filter corrects the color (subtracts the excess green + blue/green (cyan) component) when shooting 5500K (Daylight) balanced film under fluorescent light. The Hoya is probably the highest quality reasonably priced one ($18-50 for most projector applications, choose multicoated whenever possible).

    However, for projector applications, people use them to cut down the blue and green light, since most UHP bulbs are red deficient. If you can cut out just enough blue and green and you can adjust your color settings to balance all 3 colors, you can improve your contrast at D65.

    One more one to consider:
    The Sharp Notevision PG-M20X:
    Specs
    1900 ANSI lumens
    XGA native (1024x768), 720p & 1080i compatible input, as well as 1600x1200 input
    1000:1 full on/off contrast, 800:1 ANSI, thanks to new 12 degree DMD
    DVI-I input (DVI, VGA, or component), S-Vid, and Composite
    3x colorwheel
    Reasonably good scaler/deinterlacer
    5.8 lbs, just over 3" thick
    37dB of noise
    Fujinon 1.2:1 zoom lens
    $4395 retail, $2700 street price

    This seems to be one of the most popular and talked about models lately, surpassing the XB31 and H55.

    one thing generally, i believe the advisable viewing distance form the screen is 2.5 to 5 times the screen size
