Fixing the X configuration solves this. Which is why I said he should get the manual for the monitor and see what settings are safe.

Which reminds me; If you can't find the manual for the monitor, or for some reason don't have it, look it up online and find the settings it can handle.
Ahh yes good point I did have that happen once when I hooked a test monitor up that was not able to do 1280x1024...
