PG279Q Flickering with RX470

[tech_noob1]

Hi so i got myself an RX470 but when im using display port (doesnt matter which port in the back) and running 144/165hz or basicly anything above 60hz the screen will flicker on and off a few times a minute while playing games.

HDMI works fine but thats only running at 60hz.

Any suggestions?

Have you set your graphics adapter to 140Hz? Have you set the screen to 140Hz?
