Disable third-party software:
Temporarily disable any VPNs or firewall services to rule out blocked connections.
Disable third-party firewalls and turn off IPv6 in your network settings.
Remove other displays:
Disconnect any other external monitors so that only the Luna unit is connected during testing. You may be hitting the display limit set in place by the manufacturer, which isn't something we can adjust. In that case, you'd need to remove your external monitor, since Luna Display counts as a monitor.
Advanced Troubleshooting Steps
Address hardware limitations:
Some Windows devices may have USB-C or port protocol differences that prevent Luna hardware from being fully detected. Confirm your ports are functioning correctly.
The USB-C Luna unit must be plugged into a supported port connected to the GPU directly. The port must support Display Alt Mode or Thunderbolt to work with USB-C Luna.
Motherboards are not compatible with Luna Display - it must be plugged directly into the GPU.
