I was using my computer today I have two screens when all of a sudden my bigger screen (I have two) went grey and started flickering I turned it off and back on and not even the acer logo comes up it just goes grey when the logo should appear then black for a second then back to grey. normally the screen displays the acer logo then black then displays whats on screen. Any ideas how to fix this easily or is this monitor dead. I know it is the monitor and not the computer because it does it when plugged into the laptop and when nothing is plugged in. Normally the power light goes orange when nothing is plugged in however now when nothing is plugged in it stays blue but all I see in grey on the screen
