Every time i play a game or something my main monitor gets darker. Earlier i was watching some you tube and i noticed my right monitor go completely blue but my main one was still playing the video. I minimized the video and everything went blue (the audio for the vid still played). I got up to turn off my pc bumped into my right monitor then everything came back. Does this sound GPU related to you? If not any ideas why it happens. (side note the everything going blue happened during a download/ install of adobe premier). Thanks
