Thank you Jose. I did get the ticket/email/firmware and did apply it successfully. The only difference I can see is that the build date is just less than two months from the initial date which is fine.
The reason I'm working on this, and starting with the firmware, is because we have a single 4K camera connected via ethernet to this NVR connected to a large 4K LCD display via HDMI. The goal is to have a constant 4K image on the display all the time. The camera is capturing a very busy scene with lots of movement of water and other elements. Problem is, not long into standing this up, the display goes blank/off. The hope is that the latest firmware fixes this and if not, perhaps there are Encode settings (FPS, Bit rate type, bit rate) that can be adjusted if load on the NVR is too high. We are expecting the display to show a constant 4K image from the camera. This NVR is doing nothing else but helping the camera talk to the display and providing PoE. There's no recording, no other cameras, no network connection.
You guys have been super helpful. Any further insight, suggestions or recommendations would be helpful.
