I read a Digital Foundry article listing recommendations for monitors that work with freesync and Nvidia cards, listed was the ew3270u but I am having problems with black screens. The cable I am using is a dp 1.4 because I was told 1.4 is needed for HDR? The problem seems to occur when freesync is engaged ie when the frame rate drops below 60, when this happens I get random black screens, like the display is losing the signal, if I turn off gsync in the driver these issues disappear. What could be causing this? If I use rtss the problem is worse, even having that run at startup will cause a few black screen before things settle down. If rtss isn't set to run at startup there are no black screens until I start gaming (wtf?). The driver I am using is 418.91 Any advise would be appreciated.
