2. Product Features
- High-Definition Output: Supports resolutions up to 8K@60Hz or 4K@144Hz/120Hz. To achieve 8K@60Hz/4K@144Hz, ensure your host device's USB-C port, HDMI cable, and external monitor all support these resolutions.
- Plug and Play Functionality: Instantly converts your USB-C device (compatible with Thunderbolt 3/4 /USB C port with DP Alt mode) to an HDMI output for a larger screen, such as a UHD TV, monitor, or projector, without the need for additional drivers or software.
- Durable Construction: Features a high-quality braided cable that resists wear and tear. Metal connectors and a zinc alloy casing provide a premium feel and enhance heat dissipation for stable performance.
- Wide Compatibility: Designed to work with virtually any USB-C device that supports DP Alt mode, including USB C ports and Thunderbolt 3/4 ports. The maximum resolution and refresh rate output depend on the specifications of the USB-C host device, HDMI cable, and the display used.

5. Operating Instructions
- Display Modes: Once connected, your source device's operating system will typically allow you to choose between different display modes:
- Mirror Display: Duplicates your source device's screen onto the external display.
- Extend Display: Extends your desktop across both screens, providing more workspace.
- Resolution and Refresh Rate: The adapter will automatically attempt to use the highest supported resolution and refresh rate by all connected components.

7. Troubleshooting
- No Display or Intermittent Signal:
- Ensure all cables (USB-C to adapter, HDMI from adapter to display) are securely connected.
- Verify that your external display is powered on and set to the correct HDMI input source.
- Confirm that your source device's USB-C port supports DisplayPort Alternate Mode (DP Alt Mode) or is a Thunderbolt 3/4 port.
- Try using a different HDMI cable, as cable quality can affect signal transmission, especially at higher resolutions.
- Restart your source device and display.
- Low Resolution or Refresh Rate:
- Check the display settings on your source device to ensure the desired resolution and refresh rate are selected.
- Verify that your source device, HDMI cable, and external display all support the desired resolution (e.g., 8K@60Hz or 4K@144Hz/120Hz). If any component does not support it, the output will default to the highest common resolution.
- No Audio:
- Ensure the audio output settings on your source device are configured to send audio via HDMI.
- Check the volume settings on your external display and ensure it is not muted.
- Flickering or Unstable Display:
- Ensure all connections are firm.
- Try a shorter or higher-quality HDMI cable.
- Reduce the display resolution or refresh rate in your device's settings to see if stability improves.
