    Hi,

    You may press the Windows key + P to show the desktop on the computer only. Then set the display setting again.

    Then following link for your reference.

    http://windows.microsoft.com/en-US/windows7/Connect-to-a-projector 

    Also, If the issue persists, you may boot the computer in Safe Mode to uninstall the driver. Then boot in normal to reinstall it again.
