In that case, the problem is probably the monitor itself, not the 
software. It could possibly be the video card, I suppose, but I don't 
think that's likely.

I have a ViewSonic LCD monitor that goes into a crazy mode under some 
input signal conditions (possibly  having to do with my KVM, given that 
it requires one computer to be in one monitor power state and the other 
in a different one, it seems). In this state, the monitor's power jewel 
turns amber (normally signifying that's in power-save mode), the screen 
displays the "No Signal" message that is ordinarily followed a few 
seconds later by the monitor's lamps shutting off. Except what happens 
in this "crazy" state is that the lamps stay on and the "No Signal" 
message flashes irregularly for a while (usually a long while). If I 
leave it like this long enough, it will eventually "freeze" (the screen 
staying in a fixed state, the lamps on, the power jewel amber) but the 
monitor will no longer respond to any input or change in its inputs. 
The soft power button on the front panel fails to turn it off and even 
waking the computer(s) and restoring full sync and video signal does 
not bring it out of this state. The only thing that restores normal 
operation is power cycling it using the hard power switch on the back 
panel.

Basically, monitors have enough circuitry in them to allow for the 
possibility of buggy firmware. It's possible your monitor is exhibiting 
a similar bug.
