Hey all, I recently bought the older 23" HD Cinema Display (plastic casing) and it works perfectly fine except when I play Warcraft 3. Everytime I play, about 5 minutes into the game, the screen begins to display some kind of digital distortion and noise. It gets worse every second passes and eventually my screen goes completely black (but the game is still going on because you can hear it still going). Has anyone had this problem before or know what is causing it? Thanks in advance.
