Make sure that there are no fluorescent lights in the room. They seem to give the flicker effect on the screen. Also, move any speakers are any other items that may cause a magetic interference away from the monitor.
Wait a minute. I've had plenty of other monitors in here with no problem under fluorescent lights. Is this a specific defect of the M992? There was no mention of incompatibility with fluorescent lights when I ordered the computer.
I don't think it's the monitor's problem. I also ordered one Dimension 4500 recently but without monitor. I Change two monitors(first Envision then NEC), it's the same result, flickering. Normally the up-left corner sometimes flickers serverely at 85Hz. If i set it to 60Hz it dosn't flicker, but you will see a line rising slowly from bottom up. If i set 70Hz 75Hz you can not bear it, it flickers like earthquake. So i think the problem is the graphics card, Nividia Gefore4 MX420 is the worst card in Gefore 4 series. I update to the latest driver from Nividia website according to the instruction from this communitiy, it doesn't work. I think it must be the hardware problem of this graphics card, the output signal is not stable or it can easily be interfered.
That's the most possible reason. One of my friend also bought the same machine together with me. I will call him to see if his monitor flickers. If no that means replacing the graphics card can solve the problem. The reason is the quality of vedio card could be different or quality is not stable. I will call dell after i got the info.
My M992, which I've had without incident for over a year, has suddenly started to show this problem. Replacing the video card with (a refurbished) one from Dell did not help at all. What did you guys conclude was the problem?

I have the same video card. If it is defective, I'll be sending it back, as this system is only 6 days old.
