Purchased an MBP in 2010, very happy with it. Just recently I started using and external monitor(closed the lid on the MBP) and now I get screen issues like the ones in the picture below. Is having it connected to a non apple monitor causing this? anyone got a clue as to what could be happening? (first apple product so any info is greatly appreciated)

This the daily setup A tasted of the issue I get a closer look
