This is a 3440 x 1440 ultrawide display. 8bit+ color and 99% gamut range.
Half of my screen has faint vertical lines. They are only visible with certain colors. If I change the contrast, these lines get more and less visible, and only show up on some of the colors on screen. Changing the color settings also changes the severity of the lines. These are the only setting in the osd that affect these vertical lines. Messing around with different calibration tools, the lines only showed up on cyan in a basic color chart. They still show up in plenty of other places, but they only really piss me off when watching high res movies.
Any suggestions? Is this a known display issue? I have tried researching, but don't know enough to narrow down the search. I would not like to send it in for repair unless completely necessary as I am at university.
I tested both a display port cable, in 1.1 and 1.2, and a hdmi cable. Both with the verticle lines. I have tested multiple computer and operating systems. No change.
Happy to provide more info, just don't know what else would be helpful.
Thanks!
