It sounds like it's some limitation of the projecter having to do with some aspect of the video signal. If the resolution and color depth are the same, then it is probably the horizontal sync rate or the vertical sync rate. You could customize a video mode in X by running "xvidtune" as root to try adjusting the sync rates. The easiest way to check what sync rates are used in your Windows and Linux 800x600 modes, if you don't already know, is on your monitor -- most monnitors have a button or option to show the current video mode, including sync rates. Asa BTW - I just noticed that your posts to the list have a "Reply-To" address set in them -- this prevents replies to your posts from goign to the mailing list...
