There are several possible causes of your DVR/NVR that do not show its setting panel. You may follow the troubleshooting tips listed below to solve the problem.

Solution 1: Check if both ends of the HDMI or VGA cable are firmly connected to the DVR/NVR or monitor. If not working, please try another HDMI or VGA cable to connect the device.
