Dual monitor black flickering

Support Technical Support
1

Hello!

I use two monitors and whenever something is loading on one screen (YouTube video, ads etc) the other screen with WoW flickers black. This only happens when I have WoW opened, and not any other games or when no programs are open.

What I have tried to fix it so far:
Switched what screen I use for WoW.
Different HDMI cable.
Disabled full screen optimization.
Run as administrator.
Disabled all addons.
Updated video card drivers.
Updated everything else.
Selected the correct GPU in WoW system settings.
Made sure the refresh rate is the same on both monitors.

Running out of ideas, anyone that can help?

As far as I am aware, Dual Monitor setups are not actually supported by Blizzard.

Thats not the same as saying “it won’t work”, it simply means that if something doesn’t work, it’s not up to Blizzard to fix it. It is outside the scope of their support system.

As such, I would suggest reaching out to your GPU maker or monitor maker or their associated communities instead.
