Got mine home and can't get it going on displayport. Works on hdmi at 144hz and 1440p.not had time to play anything on it yet. Did notice some strange lines appear now and then across the screen when in Windows folders and stuff. Need more time to play it but might be an rma at this rate. Will get another displayport cable and see if the one they gave me was the problem. Gpu has never used the ports so shouldn't be that.
