I have a video system to allow multiple connections to a single projector that only accepts HDMI in (it's a TI Pico Projector development kit). I have an HDMI upscaler to go from my PS2 and XBOX, but discovered that the projector only supports 640x480 resolution (it's pretty old). When I run it through the adaptor I got on Amazon, it only displays 1/4 of the screen.

Every RCA to HDMI adaptor I've found looks to be an upscaler, which is what I don't want. Can anybody point me in the direction of a way to take the svideo signal and convert it to the appropriate format without changing resolution/by forcing 640x480?

This question appears to be off-topic because it is about home theater. –  AJ Henderson Oct 25 '13 at 13:40
I suppose I should have added, then, that this same setup I use for video display during concerts I produce and the exact same functionality is needed. –  mdhansen Oct 25 '13 at 19:00
Removed the word home from the question. –  Friend Of George Oct 28 '13 at 16:01
isn't svideo 640x480 by default? The "cornering" is just a form of letterboxing (without centering). If you want it to be centered and fill the screen without a change in aspect ratio, you need something which upconverts (resamples) th image. Or are you asking how to force a lower display resolution on your projector? –  horatio Oct 29 '13 at 17:22
Actually, I misread your question a little. Some of the upscalers will have configurable output resolution over the HDMI. How much support there is seems to be a function of the price. –  horatio Oct 29 '13 at 17:45
