Your system has two graphics states low res (Intel Graphics 3000) & hi res (Radeon HD 6770M or Radeon HD 6970M). The switching logic between the two graphic services appear to be in trouble here. Basically your system uses the low res until an appOS calls for the higher res. When you add in a second display Hi res is used either in mirror mode or extended desktop mode.
