I have a late 2010 13" MBP that I often connect to a 23" LG LED display (E2360) that seems to freeze randomly. During use, both the MBP display and the LG will turn white (usually) and sometimes blue or black. Disconnecting the LG will not cause the MBP to re-detect monitors and automatically fix, nor will key combinations let me restart/put to sleep the computer. I am forced to manually shut down the computer with the power key and restart. I'm using a Dynex Mini-Display to HDMI adapter. I've noticed that the problem only occurs when using the LG display AND the MBP display. The problem does not happen when running in clamshell mode and just using the LG display. Any thoughts?
