7. Troubleshooting
- No Display/Signal:
- Ensure all HDMI cables are securely connected to the correct ports on the KVM switch, computers, and monitor.
- Verify that the HDMI cables used are HDMI 2.1 compliant for 8K resolutions.
- Check if both USB 3.0 cables from the KVM switch are connected to your computers. These cables provide power to the KVM switch.
- Try restarting the computers and monitor.
- Keyboard/Mouse Not Responding:
- Ensure the USB 3.0 cables from the KVM switch are properly connected to your computers.
- Try plugging the keyboard and mouse into different USB 3.0 ports on the KVM switch.

- Screen Flickering or Instability:
- Ensure the HDMI cables are of high quality and support the desired resolution and refresh rate.
- Check for updated graphics drivers on your computers.
- The Adaptive EDID feature should prevent most display issues. If problems persist, ensure your monitor's EDID settings are correctly configured.
