This is driving me crazy!!!! Every few minutes or so I hear an alert sound and my screen suddenly changes sizes on my attached monitor (which I use with my laptop closed). It alerts me then changes to a small screen with big black boarders (the size of my laptop screen) then a few moments later it changes back to a full screen (no alert sound when going to a big screen it just suddenly does it). I have no idea what I am doing or how to fix this. I've used the monitor like this for months, but it only started doing this screen changing thing recently. Restarting my computer didn't help. Help me please!!!!
