Troubleshooting
1. The cursor has disappeared
If the status remains in the extended mode but the docking
station is disconnected, the desktop will still extend to the
add-on monitor. The cursor may not be found on the primary
monitor. If it happens, connect the add-on monitor through
the docking station again or keep moving the mouse.
2. Video playback in extended mode
If the video or DVD playback quality is poor or low
performance in extended mode, play it back on the primary
monitor instead of the add-on monitor.
3. In Extended Mode, the add-on monitor has a black
border around the desktop
This happens when the resolutions used by the add-on
monitor are greater than the resolutions used by the primary
monitor. To solve the problem, configure the add-on monitor
to use the same resolution as the primary monitor.
4. The add-on monitor is flickering
This is usually caused by a low refresh rate.
Mirror Mode – Increase the refresh rate of the main monitor.
This will in turn increase the refresh rate of the add-on
monitor, stopping the flickering.
Extended Mode – Increase the refresh rate of the add-on
monitor.
