"Cannot Display This Video Mode"

[Eustace the Monk]

It will may work in windowed mode or forcing the Resolution - changing in game_options.txt, then making the file Read Only. The other question is, has the resolution used by the operating system changed? Might try right-click on the desktop, then Properties. Then under the Settings tab, try changing your resolution to something else in there, to see if it reverts the game to a different resolution. I have also seen a few writeups where people have experienced various video problems since the change, but not this specific one yet.

Yay! You're first! Doesn't that make you happy? (Sorry, sarcasm is not that easy to see in print). But hopefully one of the things I mentioned will make it work.
