Bought a brand new KG271c today and when connected, screen shows red horizontal flicker lines every here and there depeneding on what software is running. Also dozens or hundreds green dots are flickering around the screen too and if I move any window from position to another, that window flickers while moving. Also, monitor should support 144hz but I only have option to choose 59 or 60hz. I'm using NVIDIA Quadro P620 and not sure whether it supports more than 60hz ?
Any help appreciated!
