monitor or video card?
I have an AOC LM729 LCD monitor and an nVidia FX 5200 card. They're both only about 2 years old. About a week ago, the monitor got dim (like a laptop does when you pull the plug on it to save power). It was like that for a few seconds then came back to full brightness. The past few days it's been doing that a little more often. The whole screen actually went black for a few seconds the other day. The monitor light stays green (not orange) the whole time. Any idea as to whether this may be a video card or monitor issue?
