3. Setup Instructions
Follow these steps to connect your QGeeM HDMI to DisplayPort Converter Adapter:
- Identify Ports: Locate an available HDMI output port on your source device (e.g., laptop, desktop) and an available DisplayPort input on your monitor or display. Also, identify an available USB port on your source device or a USB power adapter.
- Connect HDMI: Plug the HDMI connector of the QGeeM adapter into the HDMI output port of your source device.
- Connect DisplayPort: Connect a DisplayPort cable (not included) from your monitor's DisplayPort input to the DisplayPort receptacle on the QGeeM adapter.
- Connect USB Power: Plug the USB connector of the QGeeM adapter into an available USB port on your source device or a USB power adapter. This step is crucial for the adapter's functionality and stable signal transmission.
- Power On Devices: Ensure both your source device and monitor are powered on.
- Select Input: On your monitor, select the correct DisplayPort input source.
Important Note: This adapter is designed for HDMI to DisplayPort conversion only. It will NOT work for DisplayPort to HDMI conversion.


4. Operating Instructions
Once connected, your system should automatically detect the external display. You can configure the display settings through your operating system.
Display Modes:
- Mirror Mode (Duplicate): The external display shows the same content as your primary screen. This is useful for presentations or sharing content on a larger screen.
- Extend Mode: The external display acts as an extension of your primary screen, providing more desktop space. This allows you to multitask by having different applications open on each screen.
To switch between display modes, access your operating system's display settings (e.g., Windows Display Settings, macOS System Preferences > Displays).

5. Troubleshooting
If you encounter issues, please refer to the following common solutions:
- No Signal on Display:
- Ensure the USB power cable is securely connected to a functioning USB port. The adapter requires external power.
- Verify that all HDMI and DisplayPort connections are firm and correctly seated.
- Confirm your monitor is set to the correct DisplayPort input source.
- Test with a different HDMI cable or DisplayPort cable if available.
- Restart your source device and monitor.
- Flickering or Unstable Image:
- Ensure the USB power cable is providing sufficient power. Try a different USB port or power adapter.
- Check for loose cable connections.
- Reduce the display resolution or refresh rate in your operating system's display settings to see if stability improves.
- Adapter Not Working:
- Confirm that you are converting from HDMI to DisplayPort, not the other way around. This adapter is unidirectional.
- Ensure your source device's HDMI output is active.
- Test the adapter with another compatible source device and display if possible.
