Q: Greenish screen after wake up using external monitor

I use an 23" hp monitor with my MacBook Pro 2012. Now I have upgraded to Mavericks, after I wake up the machine from sleep the screen looks like this (a greenish screen).

I have to open the machine itself inorder to have a proper colour on the ext. monitor again.

MacBook Pro (13-inch Mid 2012), OS X Mavericks (10.9)
