Setup Instructions
Follow these steps to properly connect your UGREEN DisplayPort 2.1 Cable:
- Identify Ports: Locate the DisplayPort output on your source device (e.g., PC, laptop, graphic card) and the DisplayPort input on your display device (e.g., monitor, TV). Ensure both ports are DisplayPort and not HDMI or Mini DisplayPort.
- Connect Cable: Gently insert one end of the UGREEN DisplayPort 2.1 cable into the DisplayPort output of your source device. Ensure it is fully seated.
- Connect to Display: Insert the other end of the cable into the DisplayPort input of your display device. Ensure a secure connection.
- Power On Devices: Power on both your source device and your display device.
- Select Input: On your display device, select the correct DisplayPort input source using the monitor's OSD (On-Screen Display) menu or input selection button.
For optimal performance, especially for 16K resolution, ensure that your graphic card, monitor, and all connected cables meet the DisplayPort 2.1 requirements.

Maintenance
To ensure the longevity and optimal performance of your UGREEN DisplayPort 2.1 Cable, follow these simple maintenance guidelines:
- Handle with Care: Always grasp the connector ends when plugging or unplugging the cable. Avoid pulling directly on the cable itself, as this can damage the internal wires or connectors.
- Avoid Sharp Bends: While the braided nylon jacket is robust, avoid excessively sharp bends or kinks in the cable, which can stress the internal conductors.
- Keep Clean: Periodically wipe the cable and connectors with a soft, dry cloth to remove dust and debris. Avoid using liquid cleaners directly on the connectors.
- Proper Storage: When not in use, coil the cable loosely. Avoid tight coiling or tangling, which can put strain on the cable.
- Protect Connectors: If the cable is stored for an extended period, consider using dust caps for the connectors to prevent dust and oxidation.

Troubleshooting
If you encounter issues with your UGREEN DisplayPort 2.1 Cable, refer to the following common troubleshooting steps:
- No Signal or Black Screen:
- Ensure both ends of the DisplayPort cable are securely connected to the source and display devices.
- Verify that the correct input source is selected on your monitor/TV.
- Check if your graphic card drivers are up to date.
- Test the cable with another DisplayPort-enabled device or display to rule out a faulty port on your equipment.
- Flickering or Intermittent Signal:
- Ensure the cable is not bent sharply or damaged.
- Reduce the resolution or refresh rate in your display settings to see if the issue persists. This can help identify if your hardware is struggling to maintain the signal at higher settings.
- Check for potential electromagnetic interference (EMI) from other electronic devices.
- Resolution or Refresh Rate Not Reached:
- Confirm that your graphic card and monitor both support the desired resolution and refresh rate (e.g., 16K@60Hz, 8K@120Hz).
- Update your graphic card drivers to the latest version.
- Verify that your operating system's display settings are configured for the correct resolution and refresh rate.
- Some older DisplayPort versions on devices may not support the full bandwidth of DP 2.1. Ensure your devices are compatible with DP 2.1 for maximum performance.
If issues persist after following these steps, please contact UGREEN customer support for further assistance.
