Multi-Monitor Configuration:

3. Check the Multiple Displays > Extend these displays.
4. Click “Apply” to confirm and close the settings screen.

macOS

1. Click the Apple icon at the upper left corner of the screen and select System Preferences from the drop-down list.

Audio Configuration

When the docking station is connected to a computer, the audio configuration may be changed to a USB (Multimedia) Audio Device automatically (this setting depends on models). If it does not work, follow the steps below to set up.

1. Open the Control Panel, then select the hardware and sound icon.
2. Click Sound > Manage audio devices, then select USB Audio Device.

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 has 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 Which 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.

5. The video does not display properly in Full-Screen Mode.
   Try the following tips to improve the smoothness of video playback:
   a. Reduce the resolution of the display.
   b. Use the adapter in Extended Mode.
   c. Terminate any other CPU-intensive applications running on the computer.
   d. Some media players require DirectX hardware support to correctly operate. Try a different media player that requires less DirectX support.
   e. Drag the media player to the add-on screen and close the player. Restart the player and it should open on the add-on monitor. Now try playing the media file again.
   f. Reduce the hardware acceleration level of the primary display (NOT the add- on monitor) to levels 1, 2, or 3, then restart the media player. The hardware acceleration can be found by right-clicking on the desktop and clicking “Properties > Settings > Advanced > Troubleshoot.”
   g. The video playback may be unusual when the add-on monitor is mirroring the primary display and there is another extended screen connected to the computer. The extended screen must be disabled before the content will be cloned correctly to the add-on monitor.
