ToeFurB,
The best thing I can suggest is to check the drivers. There are also some other posts here dealing with computer issues that one member has been nice enough to post a link helping troubleshoot.
Keep me posted.

I have built a Windows XP Media center to hook to my 50" Samsung (HL50A650). However when I attempt to set the resolution to 1920X1080 on the computer the TV shows no pictures and says, "Mode Not Supported." If anyone could give me some advice on how to make this resolution work or a better resolution to run at it would be greatly appreciated. Thank You.
