Table 8-32 Issues, possible causes, and xes
Items Procedures
Symptoms
No or bad image on external monitor
via ports of docking station (VGA, DP,
TB, display port, etc.)

rmware, dock video ports (DP, VGA, etc).
Troubleshooting steps
1. Be sure that external monitor is powered on.
2. Be sure that external monitor is compatible with the computer.

number, and then click Manuals > Technical white papers.
4. If the screen image is distorted, try a DP-to-VGA adapter. Connect the adapter to each
DisplayPort and VGA port of the dock.
5. Test the monitor via internal ports (VGA, DP, HDMI, etc.).
6. Verify that dock connectors of the notebook and the dock are clean, without dust,
debris (e.g., using air duster).
7. Ideally, use a veried working operating system/system connected to the dock to
