I have a RX 590 and it started having problems yesterday. When i plugged in my displayport cable to my monitor, it started to have random lines show up on screen and sometimes turn off and on again. When i set it from 144hz to 60hz it works fine. When i uninstalled the amd drivers it also worked just fine but when i redownloaded them the problem reoccurred. When i also use a hdmi cable it also seems to have no issues
