HI all i have a pny geforce gtx 660ti with the latest nvidia drivers and when i'm watching videos with netflix app on windows 8.1, I will drag the app to my high def TV and watch them there, as soon as i'm done watching and i close the app my main monitor will flicker briefly and once that is done it will not do it again till i watch another show on my HDTV. Any reason why this would happen and is it anything to worry about?
