I have an Acer LCD monitor that I use both for my PC and my PS4. Earlier today, a black pixel with a surrounding, "shadow," appeared on my monitor. I assumed it was just a dead pixel but interestingly, I can cover it up with my cursor, and screenshots capture it. Additionally, when I switch the display to my PS4 the dot/line disappears, does anyone know what to do?
