John,
I have an interesting way to use my NVR and W10 computer using the same NEC 32" PA322UHD monitor running at 3840 x 2160. I also set up my camera analytic for event recording(not using motion) and adjust the time of day for each event to minimize wind caused shadow movement.
To set up the cameras you have to use the web interface for smart events rather than the NVR software (smart events are on the VCA tab of the NVR software). I see the line/zones with the NVR software but I can't save any changes. Hikvision has a technical bulletin on this set up procedure but-surprisingly-it was not included with information on my NVR and I finally discovered it.

I set up my cameras using the web interface and the "smart event" tab. I set up my camera(s) using the "smart event tab" to record on line crossing and intrusion detection. I place the detection line/zone and the I set the time for that zone to minimize false triggers due to sun shadows from wind. For example, I use a line crossing to monitor intrusion but late in the day the line gets triggered by wind blown shadows so I end the monitor time and switch to a different zone. I typically set the sensitivity to 50-60% and the threshold to 1 sec but using time to move to a new zone is better for my layout.
The Hikvision PTZ uses smart tracking so when a line/zone is breached the camera will orient to the area of the breach and then zoom in (user setting-I use about x4 zoom could be as much as x36). Then whatever has caused the breach and is moving is tracked by the camera for a pre-record and post record time set by the user (I use 5 sec pre and 30 sec post).
Generally the analytics work well using my tuning schedule to eliminate false alarms (mostly wind blown shadows).
I display all the cameras on my NEC PA322UHD monitor using an HDMI cable from the NVR directly to the monitor at 3840 x 2160 (@30 Hz) which is the best output from the NVR. My desktop computer (W10 Pro) hooks to the same monitor with a display port cable and I have my display card running at the same resolution but @60 Hz. I can look at the cameras from the W10 desktop using iMVS-4200 but its resource intensive and sometimes unstable. So I have a small W10 utility program which I click on from the desktop that puts the monitor to sleep and I set the monitor up to auto switch to display the HDMI from the NVR. Works very good and I do all my monitoring from the NVR which is accessible via a Logitech USB mouse hooked to the NVR. I just pick up the NVR mouse and I am immediately working via the NVR and its display of the events. To get back to my W10 desktop I grab my W10 mouse, move it, and the display wakes up up and I'm back in my W10 desktop mode. Time to switch from W10 to NVR is about 8 seconds.
I also use iVMS-4500 from my iPad and iPhone with an open port on my router for the NVR. This works good also as I can Live View and play back video remotely. Hikvision does do a good job of integrating their IOS software with the NVR.
I'm not monitoring live but I have set up the W10 desktop to auto sleep the monitor and when it does then what shows up is the NVR display since the NEC is set up to auto switch displays. Interesting to watch the NVR output when the analytics are triggered. The display will go full screen for the camera that triggers the event (for a user set time) and then return to showing all cameras again.
