1. Introduction
This manual provides detailed instructions for the BENFEI HDMI to DisplayPort adapter. This device is designed to convert an HDMI signal from a source device (such as a laptop, PC, or gaming console) to a DisplayPort signal for display on a monitor, projector, or HDTV. It is a uni-directional converter, meaning it only transmits signals from HDMI to DisplayPort, not the other way around. For optimal performance, the adapter requires external power via a USB connection.

3. Setup Guide
Follow these steps to connect your BENFEI HDMI to DisplayPort adapter:
- Connect the HDMI male connector of the BENFEI adapter to the HDMI output port of your source device (e.g., laptop, desktop PC, gaming console).
- Connect the USB-A male connector of the BENFEI adapter to an available USB port on your source device or a USB power adapter. This provides the necessary power for the adapter's internal chip.
- Connect a DisplayPort cable (not included) from the DisplayPort female port of the BENFEI adapter to the DisplayPort input on your display device (monitor, projector, HDTV).
- Ensure your display device is set to the correct DisplayPort input.

4. Operating Instructions
Once connected, your display should automatically detect the signal. You can configure your display settings on your source device for various modes:
- Mirror Mode: Duplicates your source device's screen onto the external display.
- Extended Mode: Extends your desktop, allowing you to have different content on each screen, increasing productivity.
Adjust display settings through your operating system's display preferences (e.g., Windows Display Settings, macOS System Preferences).

7. Troubleshooting
- No Signal / Flickering Display:
- Ensure the USB-A cable is connected to a powered USB port. The adapter requires external power for stable signal conversion.
- Verify that all cables (HDMI, USB, DisplayPort) are securely connected to their respective ports.
- Check if your display is set to the correct DisplayPort input source.
- Test with different HDMI and DisplayPort cables to rule out cable issues.
- Adapter Not Working with KVM/Docking Station:
- This adapter is designed for direct connection between an HDMI source and a DisplayPort display. It is not compatible with KVM switches, docking stations, USB hubs, or other signal intermediaries. Please refer to Figure 6 in the Compatibility section for a list of unsupported devices.
- Resolution/Refresh Rate Issues:
- Ensure your source device and display both support the desired resolution and refresh rate. The adapter cannot improve the native resolution or refresh rate capabilities of your devices.
- Check your source device's display settings to ensure the output resolution and refresh rate are configured correctly for the connected display.
- No Audio:
- Verify that your display device has built-in speakers or is connected to external audio output.
- Check your source device's audio output settings to ensure audio is being sent via HDMI.
