dahua nvr 5216-16p-4ks2

I recently purchased a Dahua NVR with 6 cameras from EmpireAndy and running into a problem. Using the web view, I can only see 4 cameras at a time and cannot change the view configuration to show more. Can anyone tell me how to view more than 4 at a time? Thanks!

Hi everyone, need an urgent diagnosis of my DAHUA NVR 5216-16P-4KS2 please. A couple of days ago, I noticed that none of my 11 cameras were being displayed on my tv having a long hdmi cable from one to another. Went into the log and it stated that all cameras had disconnected at the same time...
