Question Pc wont boot with dual monitor

[timp111222]

I just got G9 neo monitor, and now when i have that and predator x34 my pc wont boot.. i see the login screen for a secound then my pc restarts.
If i unplug x34 and wait for my pc to boot and when its fully booted and plug it in, it works fine. Anyone got a clue?

Update your post to include full system hardware specs and OS information.

What connections and ports are being used between pc and monitors:

GPU, iGPU?

Ports: DVI, HDMI, DP?

Any adapters being used?

If you swap the monitors around does the same thing happen?

Does the new monitor work by itself on your pc and on another known working computer?

Right click an empty area on the desktop.

You should see a menu window with a choice to access the Graphic Card's Control Panel.

Check the GPU configuration settings.

Also: Use "WIN" + "P" to open the PROJECT menu.

What display configuration are you using PS screen only, Duplicate, Extend, Second screen only?
