    > If `VIDevFPS` is not 0 and `VIFPS` is 0, it indicates that NanoKVM is not correctly configured for HDMI parameters. The Cube can replug the HDMI to auto-detect, while PCIe can click `Reset HDMI` under `Video` to auto-detect.

+1. Check if you are using a cheap DP to HDMI (passive adapter). These types of adapters lack a proper wake mechanism and cannot notify the NanoKVM that the display has been restored.
+2. For PCIe versions, you can click the "Reset HDMI" button to forcefully retrieve the display.
+3. The Cube/Lite versions lack a reset function; please switch to an active DP adapter.
