Applies to: Reolink NVRs.

If there's no video output on the monitor from Reolink NVR, you may follow the troubleshooting tips listed below to solve the problem. There are several possible causes for the problem:

 

Cause 1. The video output resolution of the NVR is not supported by the monitor/TV

Solution:

  • Ensure the lowest resolution of the TV/monitor is no less than 720p, or it won't be able to display any video from the NVR.
  • Power on the NVR to see whether the Reolink logo will be displayed on the screen.
  • Try to log into the NVR on LAN and change the output resolution of the NVR and try again. You can change the NVR output resolution via the menu of the NVR, the Reolink Client, or the web browser. The Reolink App can not do that.

Cause 2. The system program is frozen when booting up

Solution: 

  • If the NVR was once working properly, power on the NVR to see whether the Reolink logo will be displayed on the screen and then turn to black.
  • Contact the support team with your device model for a repair tool to fix the issue.

Cause 3. HDMI/VGA cable or the TV/monitor is defective

Solution:

  • Check whether the cable is defective by using it to connect other devices to the router and see if it works.
  • If it doesn't, please use another HDMI/VGA cable that is shorter than 15 meters and try again.

Cause 4. HDMI/VGA port on the NVR is defective

Solution:

  • Ensure the cables and TV/monitor you used are working properly.
  • Try to log in to the NVR via Reolink App/Client on LAN to see if it will work.
  • Contact the support team with the test result.

Cause 5. NVR cannot be powered on

Solution:

  • Ensure the outlet of your NVR is working. If not, please use another outlet to power the NVR.
  • Check whether the LED on the DC adapter is on (only for Reolink PoE NVR).
  • Check the LEDs status on the front panel of the NVR.
  • Contact the support team with the test result.
