Hello i have been experiencing a problem the last few days and I'm looking for another opinion on whether my gpu is giving out or is it my tv. Here's a video of the problem, this is about the 3rd/4th time it happened and by far the worst.

My gpu has been in use since 10/15/2020, the tv since 9/1/20. The last thing I did was do a clean install of the latest gpu drivers a few days before it started to happen. I was having a problem in apex and that was recommended. I plan on either rolling back my gpu drivers or do a clean install of win 10 the next time it happens.

Gpu - 3080 ftw3 10gb (undervolted)
Psu - evga 750w g5
Cpu - 3700x (not overclocked)
Ram - 16gb 3600 cl16 (xmp)
Mb - msi x470 gaming carbon
Tv - 49NANO85UNA

I'm currently using an Zeskit Maya 8K 48Gbps Certified Ultra High Speed HDMI Cable 6.5ft. Supposedly it's ment for hdmi 2.1, purchased the cable same time as the tv. Running at 1440p 120hz, but the last time it occurred it happened while watching a video in kodi so nothing too intensive.. the video above occurred mid video stream while the other times it happened when my tv went to sleep and I woke it up. So this last time caused some concern that I might have a real problem.

Edit - maybe it was the cable? Lol thanks, I touched the cable and lost signal to my tv. I unplugged it and replugged it in so hopefully that fixs the problem. That video just happened last night before going to sleep so I didn't do no troubleshooting yet, I was thinking too much lol should've just tried the cable. If it happenes again I'll throw up another post, thanks again for the help.
