underscan and overscan.
See the computer's operating system documentation.
If the computer's desktop is entirely black, change it to gray or a different color.

If the computer's desktop is extended across multiple screens, duplicate the
l
desktop across the screens or use the display as the only screen.
Make sure the cable is not longer than the maximum specified in the display's
l
specifications.
Make sure the cable is securely connected to the video connectors on the
l
