I have an extremely cheap Dynex 720p LCD television. When I use component cables or an HDMI cable there is noticeable processing lag, so much that I can't play FPS games very well. But when I use a VGA cable there is almost NO lag whatsoever. Also when using VGA, all of the picture settings on the TV (color, sharpness, gamma, ect) are all disabled. Native resolution is 1360x768 but playing on 1280 x 720 makes no difference in processing lag as far as I can tell.
I got here via Kellbot's blog post -- great recap of an incredible wedding! I think you inspire all those out there bored silly by conventional weddings -- <i>it really *is* possible to make a wedding fun and really make it your own.</i>
