Windows 10: changed my monitor cable and now my monitor goes black after opening a game. [help]

As it was stated the whole monitor goes black even when the game is on windowed and it happens with every game I open it also stays black no matter until I close it or alt-tab out of it.all my drivers are updated I dont have any power saving on and its definitely not a performance issue.the thing is that I changed my hdmi cable to a display port and also changed from 60 to 144hz same monitor, and also I tried changing back to 60hz but the problem continues this leads me to believe the problem is with the cable but its a new one I just bought today and I cant believe its the problem.Im left

Monitor goes Full Black unexpectedly while Gaming

My PC Monitor goes full black while gaming or when I exit a game. It is very unexpected and happens anytime. The monitor goes black as if there is no signal coming from motherboard/ PC. Please help me fix this issue.

Here is an event log when this issue happened - https://drive.google.com/open?id=0B8B2ZsQfPj-fbG9yZWdodGg0Z0U

 

Primary monitor randomly goes black

Got a monitor issue. Looked at other posts about this issue be could not find anything addressing my issue. Over the past few months, my primary monitor randomly (no pattern to the issue) goes black but the led shows it to still be working. Secondary monitor is working. Only way to get the primary back is to reboot the computer. I tried reversing the DVI-D cable but no luck, primary still goes black. Regardless of which monitor is set to primary, that is the monitor that goes black. The monitor set as secondary never goes black. Any ideas?

 

Primary Monitor goes black

I posted this same exact question in January. I was able to get it resolved by performing an In-Place upgrade, as suggested. That worked, until about a week ago. Now I am having the same exact issue again. I tried
doing an In-Place upgrade again, and it did not resolve the issue this time. I also confirmed that my NVIDIA drivers are up to date as well (I installed them yesterday).

I have 2 NVIDIA GeForce GTX 560 graphics cards in SLI and 2 monitors (a Dell connected via DVI and a Samsung connected via a DVI->HDMI -> HDMI mini) About a month ago after the Windows Feature Pack update, I started having issues with my monitors. When
only one is plugged in they work fine, so I know there isn't an issue with the cables. When I plug in the 2nd monitor, it works, but the primary screen goes black. If I open any programs, the still open on the primary screen and I have to use Windows + <Left
or Right> to move it from the primary monitor to the secondary monitor. If I open the display settings, and switch which monitor is marked as primary, it disconnects both monitors, then brings them both back on, and both display properly. But the primary
goes black again when my computer goes to sleep or is restarted. I have confirmed installed the latest NVIDIA driver this afternoon, and I still have this issue. I have tried the following:

- changing which ports/graphics cards each monitor is plugged into

- confirmed the Dell monitor's drivers are up to date (the Samsung is a generic PnP)

- uninstalled the Display Adapters completely (it switched to using the default windows driver, but still didn't work)

- unplugged the computer and the monitors for 5 minutes then reconnected them

- scanned my computer for corrupt files using sfc /scannow

Any help you be greatly appreciated, as it is very annoying to have to guess that I'm logging in, and then switch my main display every time I want to use my computer.
