Hi, I'm a graphic artist and the other day a gaomon pd1560 monitor came to me, but I ran into a problem - white noise on the graphic monitor. I have worked previously on this graphic monitor previously at home for 3 years and have never encountered this problem. But I left to study and bought a lenovo ideapad Gaming 3-15ACH6 Laptop. I've seen a bunch of tips on how to switch the HDCP Support slider on the internet, but I just don't have it. What to do?
