Occasionally (about 1 in 20 times) after I wake my computer from being in Screensaver mode, I will get a green screen. It only does this if the computer has been in screensaver mode for at least 30 minutes. Either unplugging and replugging the HDMI cable or rebooting the computer will change the display back to normal. It only does it with one screen, and I've had problems with this same screen before. Do you guys think it is just the screen, or the graphics card? Do you think reinstalling my graphics drivers would help or be worth it?
