Hi Guys,

Can I get a little advice?

I've had this monitor paired with a VEGA 64 using the supplied DisplayPort cable and recently I've noticed some pretty distracting flicker that I'm sure wasn't there previously. It's almost like PWM flicker or a poor implementation of backlight strobing. I'm still trying to rule things out and make it reproducible on demand.

If I set the desktop to 60Hz then it's very visible, however not at 144Hz. If I disable VSYNC then it's very visible, if I leave VSYNC on then it's intermittent, possibly tied to framerate and FreeSync adjusting the refresh rate to match the in-game FPS.

I don't currently have another DisplayPort cable but I'm trying to obtain that to rule it out, and I've tried multiple drivers, even removing using DDU but the issue remains.

Any ideas?
 
Thats a shame as I do like my VEGA, however I am glad it's not the monitor as finding a decent one with a fault free panel is a nightmare so I'd rather it be the GPU. I'll try and get a hold of a cheap nVdia GPU to test with.
