3. Setup Instructions

1. Connect to Computer: Plug the USB 3.0 connector of the adapter into an available USB 3.0 port on your computer or laptop. Ensure it is a USB 3.0 port for optimal performance and compatibility.
2. Connect to Display:
   • For HDMI: Connect an HDMI cable (not included) from the HDMI output port on the adapter to the HDMI input port on your external display (monitor, TV, projector).
   • For VGA: Connect a VGA cable (not included) from the VGA output port on the adapter to the VGA input port on your external display.

   Important: Only one video output (HDMI or VGA) can be used at a time. Connecting both simultaneously will not work.

3. Power On Display: Turn on your external display and select the correct input source (HDMI or VGA) that you connected the adapter to.
4. Driver Installation (if necessary): In most modern operating systems (Windows 10/11, macOS), the necessary drivers should install automatically upon connecting the adapter. If the display does not activate, you may need to manually install drivers. Refer to the STEREN support website for driver downloads if required.
5. Configure Display Settings: Once connected, your computer should detect the external display. You may need to adjust display settings in your operating system to configure mirror mode (duplicate display) or extended desktop mode.

4. Operating Instructions

After successful setup, you can configure your display settings to suit your needs.

• Extended Desktop Mode: This mode allows you to have separate content on your computer screen and the external display, effectively expanding your desktop workspace. This is useful for multitasking.
• Mirror Mode (Duplicate Display): This mode duplicates your computer screen onto the external display. This is ideal for presentations or sharing content with an audience.

To adjust display settings (Windows):

1. Right-click on an empty area of your desktop.
2. Select "Display settings" or "Screen resolution".
3. Here you can detect displays, arrange them, and choose between "Extend these displays" or "Duplicate these displays".
4. You can also adjust the resolution and orientation for each display.

To adjust display settings (macOS):

1. Go to the Apple menu > System Settings (or System Preferences).
2. Click on "Displays".
3. Here you can arrange displays, choose between "Mirror displays" or "Use as a separate display", and adjust resolution.

5. Maintenance

• Cleaning: Use a soft, dry cloth to clean the adapter. Do not use liquid cleaners or aerosols, as they may damage the device.
• Storage: When not in use, store the adapter in a cool, dry place, away from direct sunlight and extreme temperatures.
• Handling: Avoid bending or twisting the cable excessively. Do not apply excessive force when plugging or unplugging the adapter.

6. Troubleshooting

• No display on external monitor:
  • Ensure the adapter is securely plugged into a USB 3.0 port on your computer.
  • Verify that the HDMI or VGA cable is firmly connected to both the adapter and the external display.
  • Check if the external display is powered on and set to the correct input source (HDMI or VGA).
  • Confirm that only one video output (HDMI or VGA) is connected to the adapter at a time.
  • Try restarting your computer.
  • If drivers were not automatically installed, visit the STEREN support website for manual driver installation.
• Poor image quality or flickering:
  • Ensure you are using a USB 3.0 port on your computer. USB 2.0 ports may not provide sufficient bandwidth for optimal video quality.
  • Check the resolution settings on your computer. Sometimes, adjusting the frequency of operation or resolution on the monitor and/or computer can resolve issues.
  • Try using a different HDMI or VGA cable to rule out cable defects.
  • Ensure the adapter is not near strong electromagnetic interference sources.
• Only one output works (HDMI or VGA):
  • This is expected behavior. The STEREN COM-476 adapter is designed to use only one video output (HDMI or VGA) at a time. It does not support simultaneous output to both ports.
• Adapter not recognized by computer:
  • Try plugging the adapter into a different USB 3.0 port on your computer.
  • Ensure your operating system is up to date.
  • Check Device Manager (Windows) or System Information (macOS) to see if the adapter is listed, even with an error.
