I just got my G9 yesterday and out of the boxed everything looked to be going okay. I updated the firmware, tried some games and messed with 240hz. But, then this checkerbox pattern caught my eye when looking at discord. I then opened steam and noticed this same checkerboard pattern. It only seems to appear on certain applications that I’ve opened such as Steam/Discord/the edges and background of Reddit/ as well as even the GeForce experience background. But any game I play or white background like YouTube or my wallpaper the checker boxes don’t appear. If anyone has any suggestions please let me know.
Exact same problem on my G9 that arrived yesterday. Have tried messing with every setting I can think of and it always looks the same. Really seems like a hardware problem with the panel to me and I'm getting ready to return mine.
