I am having a problem when I play games where my monitor while go black. The game is still functioning and the sound is responsive, but I am forced to reconnect the monitor's cable in order for the screen to return. It happens anywhere from 5 to 30 minutes of playing games and I've encountered it in games like Final Fantasy 14 and Splinter Cell. The only reason I'm skeptical about it being a bad cable is that it happens regardless of the cable being moved at all.
Some help would be well recieved, since this is hampering my ability to play games :(
