Hello everyone. I hope the category is correct.

On my dual boot XP/Vista machine, I'm having problems displaying 1080P in Vista via VGA to a PT-AE2000U Projector. On XP, I can only display 1080i @ 30Hz. On my Vista, I can't correctly display any 1080 video. On both XP and Vista, 1080P displays crisp but it's horizontally smashed to almost a 4:3 ratio. On XP, 1080i looks good but I can sort of tell it's interlaced. This maybe the combination that it's interlaced and @ 30Hz. On Vista, I tried 1080i @ 30Hz, 1080i @ 60Hz, 1080P @ 30Hz and 1080P @ 60Hz and none will work correctly. I recentally installed Windows Media Center and it displays 1080P but it's stretched and I have to move the mouse to the left or right to see the rest of the screen. My projector does support full 1080P up to 60Hz. I'm sure this is a problem with my PC so maybe I'm in the wrong place but I've been working on this issue for a while now and I am desprate.

Has anyone had this problem or know how to fix it? Does this have anything to do with my motherboard not being HTPC compliant? I'm not trying to play Blu-Ray disks, I just want to display video in 1080P. I've tried to uninstall and reinstall the video card drivers/software with the latest. I've tried a new VGA cable.

Any help/info is appericated ladies and gents....

My PC Spec's are:

Mobo: Gigabyte GA-N680ISLI-DQ6
Processor: Intel Dual Core Duo e6700
memory: 2GB RAM in Dual Channel Mode
Video: 8800GTS 512 G92

Even though XP Pro will do 1080i? And Media Center will do 1080P stretched?

Yes, you should not be using vga (D-sub) for what you are trying.

Wow. I went out a purchased a DVI to HDMI cable and the PC reconized my projector and it works great. No tweaking needed at all. It had all the resolutions and refresh rates my projector supported. It looks great. Thanks again for a prompt response everyone.
