Bright horizontal lines on display

Hello!
Lately I've noticed a bunch of bright horizontal lines on my screen, most of them on the bottom, 2-3 really visible, but lot of smaller ones too (and some lighter ones on the top too).
They're not dead pixels or anything like that, they're just simply lighter than they should be. Straight lines. The monitor is an LG 24M37D-B (1080p 60Hz TN panel) using a DVI cable. GPU is an R9 390, but on the TV which is connected by HDMI no bright lines can be seen.
Any idea what can cause it?
I've attached a bunch of pictures because it can be hard to see

Does it still happen outside of the game you're playing?
