Here is a photo (taken by my cellphone camera) of the "bouncing window" that I mentioned. (Sorry for the not-very-good quality of the camera...)
So you are in X. Does the same bouncing window appear as well before you switch into X, on the console?
I assume I was right that a screenshot done with 'scrot' did not include the boundy window, and the mouse pointer moves "below" it?
Do you have the model number of your LCD panel handy, so that we can google for the manual and check what causes this message (and what refresh rates it supports)?
Is your monitor connected via VGA or via DVI? A VGA connector has 3 rows of pins as shown on http://en.wikipedia.org/wiki/VGA, a DVI connector looks like the image on http://en.wikipedia.org/wiki/DVI. Note that you have to check the cable on the PC end, because on the monitor end some manufacturers use their own, differently connected, plugs.
