Thanks for sharing. I'm really glad that word is spreading on this issue.
Funny enough, the guy in the first video only sees it on the left side of the screen like myself. Certain games/situations show it everywhere.
I'm certain it exists on all x34's and some people simply don't notice it. I pray there's something wrong in the latest hotfix drivers, but that's wishful thinking. It's most definitely related to the GSYNC module running outside of it's own specs. I wouldn't have noticed it initially had I not been looking for pixel inversion. On my screen, it's strong on the left side while nearly non-existent elsewhere. It's better you don't go looking for it though... Once you see it, it cannot be unseen.
Thanks for the information. The person who uploaded those videos to youtube has made a more elaborate post on the ACER forums: http://community.acer.com/t5/Predator-Discussions/MULTIPLE-Problems-with-New-X34/td-p/390434/page/21
According to PCper, the pixel inversion (or alternating bright and dark vertical lines problem or TCON artifacts) is supposed to be related to TN panels only. Source
. Which is to say that the horizontal persistent lines with the X34 may have a different cause.
So, I happily ordered this monitor thinking the LG IPS panel is not going to have an image quality issue. Alas, this G-sync issue rears its head. I'll take a close look, taking pictures with a good camera, when I get my monitor on friday. Quite unacceptable for this monitor to have an IQ issue; I can easily forgive and overlook the firmware quirks. If your supposition that all X34 monitors suffer from this issue (but go undetected by their owners) is true, it is then also unacceptable that TFT central didn't detect it. But I do hope that it is not an issue endemic to all units so that you can get a good replacement and I can get one without issues.Edited by Mountainlifter - 11/1/15 at 5:13pm
