Custom Resolution Utility (CRU)

[Danja]

Hey chaps, I've had a good read about and don't seem to be able to find out what's going on. I've got an AOC G2460FQ - which is advertised as a 144hz monitor. My problem? From what I'm reading, scan lines or PWM sensitivity.

When I run d3d apps, at 144hz, I get these weird "bars" running across dark/light stuff like fog in shadow of mordor, or walls with shadow in CSGO. I messed around with the monitor timing and managed to reduce it a bit, but I can't get rid of it.

if I turn the monitor down to 120hz its fine, I don't get the problem. Is it possible I'm seeing this because my eyes are sensitive to PWM LED stuff (which I assume these monitors are using, as their cheap...ish)
EDIT:
I ask, nay plead, for information that can help me solve this. Right now I'm on the verge of just using this a second monitor and grabbing an ASUS/EZIO that will work at the 144hz I want.

I've got the display running on a DP cable, but I've also tested with Dual link dvi cables and its the same result. I've patched the pixel clock, made sure there's no interference messing with my data cables, adjusted timing to LCD reduced, treid normal, nothing seems to get rid of the lines. They're not even aggressively noticable, but just enough of a shimmer in things like fog (about 5-10 pixel bars running horizontally across the screen) or shadows to really distract my eyes, which in something like CSGO that is concentration dependant its pretty annoying

Just to add, I've even upgraded my GFX card from a 7870 to a r9 290 recently, and that made not a scrap of difference.

Thanks!

EDIT: Forgot to mention, when I change the sync polarity in CRU, I can change how the lines appear. with a +/- sync they appear if I look upwards, or pan up d3d stuff, with +/+, they appear when I look down.
