Guest Travis King Posted July 25, 2007 Posted July 25, 2007 When we switch users and log on the next user, the screen goes black (still shows a signal) but we can still here the startup sound being played. When we turn off the monitor itself and turn it back on, then it works and we can see the freshly logged on user's desktop. The question here would be is the monitor causing this odd behavior or is it the video card? On their previous computer, they had the same monitor and it did it on their old computer as well, but both computers had a video card made by NVIDIA. The old computer's card was a GeForce3 Ti200 and the new computer's card is a GeForce 6600. I assume it's the monitor that's the problem. Thanks.

I have come across similar behaviour on television sets. Explanation for the technically minded: I would think that a momentary glitch in the video timings stops the line scan (the horizontal one) circuits from working (possibly because they are only *just* working). Turning it on and off kicks it back into life. There are many reasons that this could be so, but drying out electrolytic capacitors would be my No 1 guess. Exlanation for the non-technically minded: It's knackered.
Guest Travis King Posted July 26, 2007 Posted July 26, 2007 Re: Switching Users The monitor's a little over 2 years old. It's been doing this for around a year. We originally thought it was the video card except it kept doing this even after we put it on the new computer. Originally, we did not know that turning the monitor off and back on would make it work.
