With HDMI 1.3 on the way, there's been a lot of talk about mind-boggling color depths. In the PC world color depths are also a big deal, but software has to be designed to run at high color depths to make any difference. My guess is the DVD format operates at a fairly low color depth (8-bit?). Or perhaps color depth is defined by the compression format (MPEG 2-4, VC1)? Since this board isn't specifically labeled SD Software, maybe a knowledge poster could also report on the color depths of HD DVD & Blu-ray formats. All I've read so far is that the PS3 will have HDMI 1.3 and that PS3 games will eventually run at higher color depths. That's great, but it hardly necessitates waiting for a HDMI 1.3 HDTV (if that's the only application that will directly benefit).
