- Connect to Source Device: Insert the USB-C connector of the cable firmly into the USB-C port on your source device.
- Connect to Display: Insert the HDMI connector of the cable firmly into an available HDMI input port on your display, monitor, or projector.
- Select Input on Display: Turn on your display device and select the correct HDMI input source using the display's remote control or on-screen menu.
- Configure Display Settings (if necessary): Your source device should automatically detect the external display. If not, navigate to your device's display settings to extend or duplicate your screen.

4. Operating Instructions
Once the cable is connected as described in the Setup section, the video and audio signals from your USB-C DP Alt Mode device will be transmitted to the HDMI display. No additional drivers or software are typically required for basic operation.
- Display Modes: Your source device's operating system will allow you to choose between different display modes, such as "Extend," "Duplicate" (Mirror), or "Second Screen Only."
- Audio Output: Audio will typically be transmitted along with video. You may need to select the HDMI output as the default audio device in your source device's sound settings.
- Resolution and Refresh Rate: The cable supports up to 4K@30Hz. The actual resolution and refresh rate will depend on the capabilities of both your source device and your HDMI display.

6. Troubleshooting
If you experience issues with your MANHATTAN USB-C to HDMI Adapter Cable, refer to the following common problems and solutions:

- Correct Input Selected: Confirm that your HDMI display is set to the correct input source.
- Restart Devices: Try restarting both your source device and the display.
- Test with Another Device/Cable: If possible, test the cable with another compatible USB-C DP Alt Mode device or test your source device with another known-working HDMI cable/adapter.
