Questions and answers
HDMI not working
The HDMI on the VisionTek VT4000 may not be working due to several reasons:
1. GPU Limitation: The docking station does not use the laptop's GPU for display output. If GPU acceleration is required, the external display must be connected directly to the laptop's display output.
2. Driver Issues: The correct DisplayLink drivers must be installed for the docking station to function properly.
3. Cable and Power Issues: Ensure all cables are securely connected and that the dock is powered on.
4. Display Settings: The external display should not be set to "Disconnect" in the Display Settings of the operating system.
5. MacOS Security Settings: If using a Mac, follow DisplayLink instructions to adjust security preferences for proper functionality.

If your VisionTek VT4000 has no signal from the HDMI cable, try the following steps:
1. Install Drivers – Ensure you have downloaded and installed the latest DisplayLink USB Graphics Software for your operating system.
2. Check Connections – Verify that the HDMI cable is securely connected to both the docking station and the display.
3. Try a Different Port – If possible, test with another HDMI port or use a DisplayPort connection.
4. Restart Devices – Disconnect and reconnect the docking station, then restart your computer.
5. Set Display Output – Go to your system display settings and ensure the external display is detected and enabled.
6. Test with Another HDMI Cable – The cable itself may be faulty.
