I'm currently using a laptop running windows 10 and have an ASUS monitor connected via HDMI as a second monitor. It functions properly and for a few months there's been no problem playing games (CSGO, Rocket League, and Minecraft) on the second monitor. Now however, after 10-20 minutes of running any of those above games, the screen glitches to become what is shown in the picture, and both the second monitor, and my laptop monitor freeze, leaving me unable to move or even ctrl + alt + delete so I just have to turn off my computer and turn it back on. I'm not sure why this keeps happening, and the weird thing is for that first 10-20 minutes it works fine so I'm not sure what triggers it to glitch like that.
