I know this thread is old, but anyone having same issues I want to share the way to fix it unfortunately if you are having same issues as @Fireflew it seems that changing to lower refresh rate of monitor will remove those lines. The issue I suspect is poor quality of ISP panel and company trying to squeeze few extra features like 75hz 144hz for lower price, but ISP quality is not good enough, so it's probably protection for monitor because it's factory overclock and they don't want returns or people complaining.
