Hi,
I'll try to be as informative as possible, I have an InFocus 4805 projector with a Native resolution of 854x480. I know its better to run a projector at its native resolution but for some reason I swear 720p looks better on this projector even though its really being downscaled. My problem is XBMC Live will not let me change the resolution to 1280x720. My setup is a XBMC 10 Dharma Live on a Zotac MAGHD-ND01-U I have a long DVI cable wired through my attic (I can get 720p and 1080p through this cable on my PS3 so its not the cable or adapter) it has a DVI to HDMI converter on the end and thats what plugs into my PC. my question is can I force a resolution of 1280x720. Ive searched around and tried alot of xorg.conf changes but nothing seems to work. When I start up I still get the 854x480. Thanks for any help.

You're going to need to really force xorg to ignore ALL edid information and only use 1280x720... something like this except replace the 1080p line with 720p modeline information. I don't use 720p on either of my sets, but I'm sure you can find information on the standard somewhere like here. http://www.mythtv.org/wiki/Modeline_Data...dard_Modes
