    native resolution is 1024x768 and if You give signal from dsub 1024x768 You dont need 1:1maping becouse this is 1:1, but if You want use HDMI 1280x720 yours PDP ll use 1366*768 but quality will be worst like dsub IMHO

    There is (almost) no TV set which support 1:1 pixel mapping on HDMI. So even if you use 1024 x 768 over HDMI your tv set will overscan! Read the forums all over internet. To use 1:1 pixel mapping for TV's (which have no native resolution of 720p or 1080p) you have to use VGA not HDMI.

    My Mirai 32" LCD TV supports 1:1 pixel mapping through HDMI. I using a cheapo DVI - HDMI cable from eBay to output from ATI x300 to TV.

    Picture noticeably crisper through HDMI than VGA.

    It seems to depend on the TV electronics rather than the price of the LCD TV!

    A related question - i'm driving the HDMI port on my projector from the DVI out of the 6800gt card in my PC. If the PC is powered up before the projector, i get no image when i turn the projector on. Is it possible to force the PC to output via DVI regardless of whether theres anything attached?

    One of the things that has not been mentioned is refresh rates. For good viewing I think that having the correct refresh rate is perhaps the most important thing. If you are in Europe you probably want to use a refresh rate that is a multiple of 25...
