But then my card / screen may be fried. And the human eye cannot see distinct pictures at refresh rates beyond about > 30-40 frames per second.

Screens still have a long way to go. The rest of the mail looks like trolling, so I'll just leave those parts alone. I only need one of the following three: - Reference documentation where the capabilities of my screen is explained. - A working method for finding this information on my own. - A good explanation for why I should ignore the X.org warnings. -- Victor Engmark Quidquid latine dictum sit, altum videtur - What is said in Latin, sounds profound
