Hello,

For 2 weeks now I see these weird cloud lines on the top of my monitor PG278QR (pics attached), i'm using a display port cable.
I tried the following, but still the weird lines show up

• Connecting a different cable HDMI to my laptop
  
• Connecting to a different display port on my graphic card
  
• Disabling G-sync
  
• Resetting screen settings
  
• I though it could be power interference, so I changed the monitors location, with no luck
  

The monitor is connected to a GTX 1080 TI, I don't have any other screens. I bought this monitor in 2017

Any ideas what could be doing this? or is this a hardware issue?

Thank you
