I have DVR Dahua 16CH and I connect one monitor with HDMI cable and another with VGA. At the moment I see the same image on both monitors. Can I program DVR so I can see cameras from 1 to 8 on the first monitor and cameras from 9 to 16 on the second monitor? So far I managed to see the same image on both monitors or I see all 16 cameras on one monitor and on the other one all camera images are changing (spot). DVR is not connected to network. Thank you.
