XB271HU Flickering and Pixel Distortion

ppram · July 1

I bought the Acer Predator XB271HU a month ago and ever since I got it I've been dealing with infrequent screen flickers that last for only a fraction of a second. When the display comes back, however, there's a few columns worth of pixels going down the middle of my screen that are distorted. It's very easy to see if there's text there; the letters are skewed and unreadable. Furthermore, an even more bizarre issue is that sometimes it will clone whatever is displayed in those few columns of pixels and show it on the right side of the monitor (see here https://i.imgur.com/VVPKYAT.jpg). Turning the monitor off and on again will fix the issue. I've searched for solutions but I've seen many different things and I'm not sure if it's an issue with the monitor's firmware, nvidia's software, or the DP cable I'm using.

DP Cable: https://www.amazon.com/gp/product/B07MJ93FQQ/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

GeForce Experience Driver Version: 451.48

Monitor Firmware Version: 20190613_0_3010_14

Does anyone know of a solution to this?

I've heard of similar symptoms when the DP cable isn't fully seated at both ends. They should click into place. That cable supports DP 1.2, and I believe your monitor is also DP 1.2, so it should work. It's somewhat longer than I would have chosen though, and the longer the cable the more degradation occurs.
