Chapter 7: Troubleshooting
Problem:
In extended mode, the add-on monitor appears to have a black border around the desktop.
Solution:
This happens when the resolution used by the add-on monitor is larger than the resolution used by the primary monitor. To solve
this problem, configure the add-on monitor to use the same resolution as the primary monitor.
