Recently a line has started to appear down the very middle of my monitor. Usually if I move around my monitor, it goes away and comes back later, but this time it's persistent on staying. Normally it's a lime green line, but this time it's a light grey line that can really only be noticed on a dark background or in games, but it won't go away. It's not the HDMI cord because it shows up even on the "No Signal" screen when I unplug the HDMI cable. My monitor is a HP24yh, nothing crazy, but I have it overclocked to 75hz. I tried disabling the overclock and that didn't help at all. Any help would be appreciated, thanks!
