Dear Customer,

Please try these steps:

Start > Control Panel > Hardware and Sound > Device Manager

Once the Device Manger box opens expand the "Monitors" tab

Left Click and Uninstall the monitor listed.  Make sure to also check the box that says Delete Drivers.

Then select the Scan for Hardware Changes Icon.
