I have set my computer to put the monitor into standby mode after 10 minutes of inactivity - during which my monitor is still powered on but the PC shuts off the video. To wake it, usually bumping the mouse or pressing any key/button will wake it. I have found recently that sometimes it won't come out of standby. Moving the mouse won't wake it, hitting keys won't wake it, it just remains in standby mode - the PC is still on and running but the display won't wake. My monitor has two power switches - kinda like a PS2 or PS3, it has a toggle switch I/O on the back of the unit that must be flipped to the "On" position and then you can push the button on the front to turn it off and on. What's most peculiar is if I push the power button on the front of the monitor, wait a second, then turn it back on - I hear my video card fan cranking up to 100% (idle speed is about 40% but I can tell that it's running at 100% when I do this). I have two GTX 260's in SLI and only one of them is doing this (my primary which is the one the DVI is plugged into). After a few seconds it goes back to idle speed, then the monitor continues flashing as if it's receiving no image at all. I can repeat this as many times as I want by turning the monitor off and then back on as well. The only way to fix the computer when it does this is hitting reset - after which everything works just fine.
I do not understand this at all. I'd normally suspect overheating, but A) My computer is idling doing nothing, and B) The primary card is the most well ventilated of the two hence why it's the primary one, it has plenty of air flow via several 120mm fans in my case. It's stupid because this happens randomly - plenty of times my computer will put the display into standby and I can wake it with no problems. I'm using Win 7 Pro 64-bit should that matter. I have the latest Nvidia drivers installed, no extra video card programs running or anything - just EVGA Precision tune to monitor my temperatures, I don't use the overclocking portion at all. What is the problem here? Anyone have any thoughts as to what it could be? It's driving me crazy and like I said only started recently. I prefer not to disable the standby mode for the display as I like it to shut off after periods of inactivity and not stay on the screensaver - this would mean I'd have to turn the power off on the front of the monitor and I always thought standby mode was better for a monitor than turning the power off and on all the time. My monitor is a Samsung 244T if that matters, although I suspect either the video card or something in Windows as the culprit.
