    Hello curtdav,

     

    It sounds like you are getting a graphical anomoly when unplugging an external monitor. I recommend these troubleshooting steps from the article named:

     

    Apple computers: Troubleshooting issues with video on internal or external displays

    http://support.apple.com/kb/ht1573

    Reset the system

    You can reset the Mac's parameter RAM and SMC.

    Reset the resolution

    Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:

    1. Start up in Safe Mode.
    2. From the Apple () menu, choose System Preferences.
    3. Choose Displays from the View menu to open the preferences pane.
    4. Select any resolution and refresh rate that your display supports.
    5. Restart your computer.

     

    Thank you for using Apple Support Communities.

    Take care,

    Sterling

    Thank you for the help, but reseting the SMC and PRAM did not fix the issue.

    Is there a proper way to disconnect the external display from the laptop?
