hi im planin on buyin a xga lcd projecotr soon and like the majority of first time buyers of pj i hae this question. Should i run my pj and dvd in 4:3 ratio or the 16:9 ratio. Now majoirty of my viewing will be dvd's and hdtv so i know i should buy the 45*80 ratio screen (a 16:9 ratio) but my question is tat i heard when u run your pj in 4:3 ratio you use the full resolution of the pj but in 16:9 you loose a little. So wat should i do should i run my dvd and pj in 4:3 ratio and use all the resolution and get the 45*80 screen or run the pj and dvd in 16:9 ratio and get the 45*80 screen.....


ps ....if i run the pj and dvd in 4:3 ratio and get the 45*80 screen ill just move the pj back enough so the black bars just project above and below the screen......


any help is appreciated ....thanks


:confused:

I'm currently running my projector in 4:3 mode with no problems what so ever. I have built a parkland Plastics 16x9 screen and am planning on testing this with the Sanyo PLC-XW15 that I have. The question that I have... is there any other way beyond masking the top and bottom of the screen to remove the black bars when projecting at this aspect ratio?

I am new to this, but I don't see how you can "use all the resolution" when projecting a 16:9 source using a 4:3 projector. You are going to lose 33% of your resolution and light to project black bars. The only way I know of is to buy an anamorphic lens for your projector ($600 - $1200). That will allow you to use your full resolution and most of your light.

Hey all!

The only way to allow you to use the full resolution of the projector while watching 16:9 is to use an anamorphic lens, such as the Panamorph. That optically compresses the height so that you have a 16:9 image while maintaining the full resolution display. The only other way to use the full resolution of a digital projector is to get a native 16:9 projector.


Thanks!

And if you run the DVD in Pan and Scan (4:3) you're going to lose information from the DVD.

What I want to know is does running a 4:3 projector in its' 16:9 mode result in a loss of resolution of a 16:9 anamorphic dvd?


Let's say we have a 800x480 panel projector (like the AE100). It supposedly displays all the resolution of an anamorphic dvd.


If you use a 800x600 4:3 projector that has a 16:9 mode, would it not give you exactly the same resolution for a 16:9 signal that the 800x480 projector gives?


I don't care too much if I'm not using the full resolution of the projector. What I am interested in knowing is whether I'm getting the full "resolution" of an anamorphic DVD using a 4:3 projector's 16:9 mode as I would if using a wide panel projector.


Any comments are welcome.

If you use the 16:9 portion of an 800x600 panel you will use 800x450 of it's panel. If you use the 16:9 portion of a XGA you use 1024x576 of it's resolution.


The AE100and Plus Piano are actually 848x480 panel projector.
