I bought a video to vga upscaler to increase the native resolution on my X1 made by infocus. Infocus says the max resolution is 1024x768 native is 800x600. I assume this shouldn't hurt the projector. I will say that vcr tapes and regular tv are much crisper. Here is the http://store.yahoo.com/golden-bridge/kworvdckwtve.html link to the upscaler I bought.
