Monitor turns on and off randomly

[rowanbecker]

Tonight I just logged into my PC, and when I went to play Overwatch, after launching it my main monitor started to turn on and off every few seconds. This is a new monitor, and I really hope it is not broken or anything. FYI Stuff:
I have two monitors, a 1080p and 900p, and when the main one (1080p) has been doing this tonight, the other one has been working perfectly fine.

What I've tried:
I have overclocked my GPU, and I tried turning to stock, and it still happened.
I tried plugging the monitor into another wall socket.
I check the cords, they are all plugged in correctly and completely.
The monitor still turn on and off when playing other games, but it does not happen when I am just using my PC.

Any and all help would be GREATLY appreciated.

The cable you're using is low quality. I had the same problem and replaced it with a higher quality cable.

Do you really mean 'off' as in you have to press the monitor's power button again or 'off' as in it goes blank for a second or so? If it only goes blank for a little while, that might be a loss of display signal sync.

Try swapping cables between your two monitors if you can, maybe you have a bad cable or GPU port issue.

Another possibility is that the GPU itself is having issues that are degrading display cable signal quality when the GPU is under load.

Unless you overclocked monitor outputs, there should be no difference between 2D and 3D as far as the monitor is concerned, so I can't imagine how that would cause the display to actually turn off only while playing games if that's really what you meant. A monitor defect would cause the display to turn off regardless of what you are doing.

Thanks for the quick responses, but through a bit of experimenting just now, it seems that updating the GPU drivers fixed it. The reason I didn't try this before was because I just updated the drivers yesterday. I guess they messed something up in the last update, and this one was quickly released to fix it? Anyways, Ill try changing out the cables if this happens again later, then get back to say whether it worked.
