Question Monitor flashes black randomly

[Pawaxx]

Hi,

My ASUS ROG Swift PG278Q randomly flashes a black screen every now and then. It doesnt happen often but its very annoying when im gaming.

Its a 144hz 1440p monitor connected with the Displayport cable that was supplied with the monitor.

I have tried to:

• Uninstall and update drivers of both monitor and GPU.
• Disable G-sync
• Set refresh rate to 60hz
• Stress tested PSU, CPU and GPU
• Disable windows services (Problem Reports and Solution Control Panel and Windows Error Reporting Service)
• Tried switching screens with a friend who also has a 144hz asus screen, we both found no problems.
• Switching displayport cables

The problem also occurs when booted into safe mode and when performed a clean boot.

I hope someone has any ideas about what i could try next.

Thank you in advance for your time and help!

try a different DP cable

other than that, your monitor might be faulty

Thank you for your reply.
I tried it when i switched with my friends screen, unfortunately the problem still occured
There might be a possibility that both the dp cables are not sufficient but everything works fine with his build.

I might have found a way when it doesnt happen and that is when i set the resolution of the 1440p to 1080p.. But yeah.. thats not really a solution

So you have tried switching your GPU, maybe from your friend? Best answer might be that your GPU is faulty.
