Every single NVR comes preset to a video output resolution of 1280x1024. What this means is that any time an HDMI cable is plugged in to an HDTV, it may result as a blank screen even if the NVR is operational.
If this occurs, please follow the steps below.
Procedure using a VGA cable:
- Connect your NVR to a computer monitor or TV screen with a VGA cable (the HDMI cable should not be connected during this process).
- Boot up your NVR and you will see the interface appear and will be able to login. On a TV, please make sure you switch the “input” to VGA.
- On your NVR, open the Main Menu by left-clicking once on the live feed screen and, under the Settings row, please click on the System icon. Then, on the new window, click Display from the list on the left column of options. Change your resolution from 1280x1024 to 1920x1080 and click Apply down below. Your NVR will reset to effect the change.
- Disconnect the VGA cable and connect your NVR to an HD monitor or TV using an HDMI cable. Don’t forget to change the input to HDMI on a TV. Your interface will now appear and you can use your NVR freely.
