Multiple projectors to increase resolution

[dracul]

Left side of image upscaled and cropped first and then output to desktop 1. Not sure . You tell me.

Right side

So you need a 3 gig machine to play this back upscaled?

What about qxga 30fps?

I think you're misfiguring the aspect ratios...
Two 4:3 screens side by side adds up to a screen ratio of 8:3, or we can break it down to 2.666:1.
since 2.6(width) is more than the 2.35 of 2.35:1, this means that with the side by side 4:3 setup you will have a black bar on the left and right sides of the screen because a 2.35:1 video source won't fill up the full width of a 2.6 to 1 display.
If you were to do any cropping, you would have to crop a horizantal stripe from the top and bottom of the video to get it to fill the full width of the screen.
One easy way to deal with this would be to make the screen you project on a 2.35:1 aspect ratio, instead of matched to the projector, that way the black bars on either side would be off screen anyways, and your screen would be full. of cource if you used it for your pc too it would throw part of your desktop on the wall instead of your screen... pros and cons...

To elaborate here is what i'm saying it would look like with no cropping.

And how I think it would need to be cropped to fit on all of both screens:

Ignore your orignal lines on both of those pictures of course...

This seems to be a recurring subject on the forum. I've seen it discussed with interest in several threads.
Perhaps we need a sticky Multi Projector thread.
What say you Multiplexor? Sticky Multi PJ?

uhm i already said it would be WIDER than the widest dvd so you would have black bars on the SIDES and cropping would take off the top and bottom, and for dvds you only need a 1 gigahertz becuase my buddy has a qxga laptop lcd with only a 1 gig cpu and it automatically upscales it with great quality and no need for extra software, he uses powerdvd and so do I, but with an hdtv card i think you might need a 3 gig becuz thats what microsoft said!

What do you mean hdtv card? . You mean a card that can decode mpeg2 hd?
My nvidia card can play qxga res video.
I think I understand now. Its the mpeg2 decoding that requires the cpu. Taking a 720x480 mpeg 2 dvd and upscalling requires the same cpu as playing a dvd. Playing an upscaled dvd to qxga is all video card memory and ram maybe. But I think you already said this havent you. Ok just clarifying for myself . Correct?

So its decoding a true hd mpeg2 signal that requires 3gig cpu. That sounds right.
