Ok, I'm mystified by this one. I have a client with an AOC 17" monitor on a P2 computer. The problem is, periodically the monitor will lose video (the power light stays green, it does not go into sleep mode). I've tried using a different monitor, as well as a different video card, and neither solved the problem. There is another system with identical configuration on site, and it has no problems, so I know it is not a hardware conflict. Usually when the video cuts out, it does it when they print from the workstation, and lasts for 15-20 minutes before the monitor comes back on. Any ideas what could be causing this?
