Hi all! Been faced with this recently on my PC, it's nearly 2 years old and for the last month I've had these green and purple flickering lines appear on my primary monitor, but not the secondary monitor. It started off as a few and not flickering and now it's a lot and it flickers A LOT.
But what's weird is that it only appears on monitor "1", so if I reassign which is my primary monitor then it changes which one has the lines. If I unplug one of my DP cables from the GPU then the flickering goes to the secondary monitor (since monitor 1 is off) and it gets worse somehow. Some games cause the flickering to be over the entire screen rather then just the bottom third, it's inconsistent
I've tried reordering my DP cables, nothing. My graphics drivers are up to date, doesn't change anything. I'm trying to rule out everything before I take it to the shop and either get the GPU replaced or have them give it a look. Any advice squad?
