Unhappy Flickering red horizontal lines on screen

Hello all,

I am having issues with the display of my computer. On the desktop and on certain applications there are flickering red horizontal lines. Also some blacks of color show up as just flickering red. These lines do not appear in any screenshots that I tried taking. I just built this PC and it was my first build so I'm having trouble with identifying the problem. I have tried looking at other forum posts as well, but none of them resolved my issue. I have already tried updating the drivers and windows 10. Also, I have tried using differnt HDMI cables. I am not able to try another monitor though since I only have this one. The monitor works fine though when I plug in my xbox to it.

Computer Specs:
-2 TB HD
-32 GB RAM
-AMD Ryzen 7 3800 CPU
-EVGA RTX2070 Super GPU
-750 Watt Power Supply

-28" UH750 QLED UHD Monitor by Samsung

I will attach some pictures I took with my phone.

Default Re: Flickering red horizontal lines on screen

Do you have another GPU to put in to see if your current GPU is the culprit? Since the monitor works fine on your Xbox that seems to rule it out. You have already tried other cables, as well.
