Putting the resolution to 1920x1080 Makes the screen flash quickly repeatedly. Its impossible to play with the constant flashing. The screen sort of becomes super bright then dark again really quickly forever. 1920x1080 is my monitor resolution. Anyone know how to fix this problem?

Hello!

Whats your operating system? (If 10 you can try this suggestion in the video). Is your graphic video card driver up-to-date? Have you checked your monitor's VGA cable (try removing it and plug in back). Whats your screen refresh rate (Hz)?
Try this general tweaks and see if it's correct:
1. Host/Join any game room and set your game settings as recommended below in the image:

2. Check your monitor "Picture Mode" setting.
3. Adjust your screen gamma range. Go to start menu and search for "Calibrate display color" and open it and then follow the steps as displayed there and set right one.

Hope this helps you out, take care.
