I gotta say, Vizio's CMS and user controls are pretty amazing -- by far the most dynamic I have encountered on any brand TV at any price point. That's not to say I am happy with the picture, or the motion handling yet. Still holding out hope. But for a brand that had a rep for economy sets, this is a pretty significant user interface. It is not common on the other major brands I have owned -- Panasonic, Samsung, Sony, LG -- for example to allow the user to create 8 unique custom picture modes/settings PER input, plus even more for the internal applications. I have been able to start with something like "Calibrated" or "Calibrated Dark" then create one-off names to reflect my experimentation -- "CNET settings" "S&M 1" (first attempt using the Spears & Munsil disc), etc. and toggle between them. Pretty cool. My only wish list for it is that I could "copy" a set of settings to another input without having to do so manually. I also like how I can custom the names of all the device inputs. The guided setup of the universal remote with the quick search of brand and model was decent. And I was presently surprised when the volume control worked on my DirecTV remote even though the TV's speakers were set to off because it was outputting 5.1 to a sound bar -- something most TV's don't even do -- and it was smart enough to figure out to send the volume adjustment to the sound bar.
Just a smart, robust interface for the most part. Just hoping the picture can get there too. Still, miles ahead of the 2012 Vizio I have.
