Generally, HD TV's with HDMI provide the best "bang for the buck" regarding best looking and largest screen per $. And quality HDMI cables of suitable length are reasonably priced. However, once you exceed a certain length it is generally recommended to use an "active" cable.
For example a 32" PC monitor with VGA/DVI/HDMI inputs could be several hundred dollars but a 32" TV (not "Smart") with HDMI may cost less than half of that. Walmart sells a 32" 720p TV with HDMI for $80, a 1080p for $110 !
If your NVR has an HDMI port I'd consider that route.
