  • Check that the cable is securely connected to both the source device and the monitor.
  • Try connecting to a different DisplayPort input on your monitor, if available.
  • Restart your source device.
• Flickering/Unstable Image:
  • Ensure the cable connections are firm and not loose.
  • Reduce the resolution or refresh rate in your device's display settings to see if stability improves.
  • Update your graphics drivers on your source device to the latest version.
• No Audio:
  • Check the audio output settings on your source device to ensure audio is directed to the DisplayPort.
