Artifacting only in 1440p.

[Guffmaw]

I bought a new display port lead because i thought it was causing artifacting, i recorded my screen and it didn't show up so i ruled out GPU problem. New displayport lead arrives and no change, so i was thinking maybe the connector. Tried a different monitor it worked, but it was only 1080p. so i tested the monitor i have the problem on in 1080p instead of 1440p. and it works. i have no idea where to go from here.

 

Attached a video of the problem.

dose your monitor support gsync compatible and have you got gsync enabled?

I think that's the problem. Try disabling it and see if it continues. I'm having same kind of problem but at 144hz when having it enabled.

Nope Disabling GSYNC did not improve it, neither did putting my refresh rate to 60/144

Strange that. Sorry it didn't help. Have you tried using just HDMI?

Yes HDMI work, but need DP for 144hz.
