I recently bought the LG 34GK950F-B, only had it for roughly 3 months. I came home from work yesterday and suddenly there are dark lines going through it. It's a bit difficult to see depending on the background, but when playing games its super annoying. I started fiddling around and changing every setting I could find to no avail, turning freesync off and reducing response times on the monitor, but nothing changes until i switch the refresh rate to 60hz. When I do that, the dark lines get bigger and it looks awful. Also, if I leave it on a screen that is mostly white, it starts flickering really badly. I'll include pictures, any ideas how to solve it?

In case I'm missing what is going on here, you're saying the dark lines are a problem, and also appear on the PS4?
This sounds like a defect in the actual driver board ($30 part probably.) It might be repairable, but if it's under warranty, definitely RMA it.
The reason I say that is that it's on both inputs, and it's constant across the panel, which means that it's not a defect isolated to the actual panel itself, but the image being written is skipping every nth scanline, which alludes to probably a short or something on the board.
