Whenever I play BO2 on Steam, after a few minutes of gameplay my monitor says “DVI no signal” and shuts off, and will not turn back on until I restart. I’ve updated my drivers but I suspect this isn’t the issue as I’ve played many, many other games and not had this problem, so I believe it’s due to BO2 specifically. I reinstalled and verified integrity of game cache and it still does this. Switching to windowed mode solves the problem, but windowed borderless and full screen cause it.
 
Solution
You monitor cannot operate on the resolution or the Refresh Rate that Black Ops 3 is running on. Change the resolution of the game and Refresh rate (-Refresh XX in launch options)
