Go to the page for the LCD program box:

Then look under the video tab, should explain most of it. Except you might need to update the box itself first, select it under Device at the top of the software window on your PC. And update the software twice, it doesn't seem to take completely the first time, you might even get an error message. Just try again.

There's a pretty good thread in the on road forum for help too:
