But then my card / screen may be fried.

And the human eye cannot see distinct pictures at refresh rates beyond about

http://www.100fps.com/how_many_frames_can_humans_see.htm - Interesting
reading in that respect. 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.
