Image Quality: No picture on monitor / TV after connecting to DVR / NVR

If you have connected your DVR / NVR system to a monitor and are not seeing a picture, it may be related to issues with your cables, monitor, or DVR / NVR resolution settings.

To check your DVR / NVR cable connections:

  • Ensure that the video cable is not loose or has become disconnected. Check the video cable connection to your monitor / TV.

  • Try a different cable of the same type to ensure the video cable is not damaged or broken.

  • Check if your monitor / TV and DVR / NVR system support High Definition Multimedia Interface (HDMI). If they both do, connect an HDMI cable between the TV and DVR / NVR. It is recommended to use HDMI when available.

  • Check if your monitor / TV and DVR / NVR system support VGA Cables. If they both do, connect a VGA cable between the monitor / TV and DVR / NVR.

  • If your DVR / NVR supports DVI only, connect a DVI cable between the DVR / NVR and the monitor / TV.

    TIP: You can also purchase adapters to convert DVI to HDMI or VGA for your TV or monitor.

  • If your monitor / TV only has RCA Cable inputs, you can connect it to a Video Output port on your DVR / NVR using a BNC or RCA cable and an adapter.

  • If you are using a BNC cable, use Lorex model BNCB to connect to an RCA input on your monitor / TV.

If you have checked your DVR / NVR cables and are still not getting a picture, try resetting your monitor connection with your DVR / NVR.

To reset your monitor connection:

  1. Power off the monitor.
  2. Power cycle your DVR / NVR. To power cycle your DVR / NVR, please power off and disconnect the power source for approximately 30 seconds. Reconnect the power source.
  3. Power on your monitor.
  4. Power on your DVR / NVR system.

If you have reset your monitor connection and are still not getting a picture, check your monitor / TV input channel. Ensure that you have selected the input channel on your monitor that is connected to your DVR / NVR. Refer to your monitor user manual for information on how to select input channels.

If you have selected the correct input channel on your monitor and are not seeing a picture, check to ensure that your DVR / NVR is set to a resolution that is supported by your monitor.
