Hi,

I updated the firmware on my Dahua DHI-NVR2104HS-P-12 and now it has a black screen.

It shows the boot up logo etc, and then just goes to a black screen. What can I do to fix it?

Thanks
 
Sounds like maybe the resolution the HDMI is putting out is higher than the monitor.

Log into the NVR via a web browser and change the resolution to a lower resolution until it shows up on the monitor.
 
OK thanks I will try that.

Another problem I had is the camera all went status red with it saying pending.

I deleted them all, and then they couldn't be found. Any suggestions on what may be going on?
 
Reboot.

Did you change the password on the NVR? Or cameras?
 
Were you using the web interface or connected to the NVR with a monitor and mouse?

What exact FW did you use (Dont upgrade FW )
