Updating to Solve Issues

NanoKVM Pro will periodically update applications, and some issues may have been resolved in newer versions. Therefore, please try updating the application first.

System Boot

Green LED Blinking

The green LED serves as the power indicator for NanoKVM Pro. If a power source with insufficient capacity is connected, the green LED may blink due to voltage instability and fail to start up. Please disconnect all power connections and replace the power adapter.

NanoKVM-Pro supports video capture and loop-out functions. When only capturing video, it reports a maximum resolution of 4K30FPS to the host by default. When a loop-out display is connected, it reports a common resolution list.
For the default resolution and frame rate list, please refer to here.

When connected through video adapters or docking stations, the reported capabilities may change (e.g., reporting 4K60FPS capture support, which may cause capture failure). In such cases, adjust the display settings in the host system:

  • On Windows: Go to SettingsDisplayAdvanced Display Settings → Select NanoKVM-Pro display → Display Adapter PropertiesList All Modes → Choose the desired mode → Click Apply or OK.
