Ok guys, here's my complete thoughts & impressions on my Vizio V436-G1 TV. I've had this TV for almost two weeks now and so far I've been quite impressed for the price around here. This TV replaced my almost two year old LG 43UJ6300 which was an alright television but obviously due to the nature of IPS technology the black levels weren't that great & neither was the contrast, plus the HDR on there I couldn't really tell much difference between HDR and SDR content. This Vizio on the other hand I felt the blacks were much better than the LG as expected from a VA-based TV, contrast is fine too, and the HDR despite only 400 peak brightness even the HDR I felt it was better on the Vizio than my previous LG TV. The 10 local dimming zones on the G1 version of the Vizio V-series TV actually does help out with the dark scenes of different movies & video games, you'll be hard pressed to find anything better around the same price, even putting the TCL 5 series to shame a little bit. I've tested many things on the TV from gaming (I play Xbox One X) to watching movies (both disc and streaming) and so forth, and again for the price the Vizio V436-G1 performed pretty well on almost all of them. On gaming, the input lag is low 99.99% of time and you'll be glad to see that this TV supports HDR10 (the standard dominating format), Dolby Vision (Dolby's HDR format that's considered better than HDR10 because of 12-bit colors and the higher 4000 nits vs just 1000 nits on HDR10) and HLG, sadly as expected from Vizio the upscaling of 480i, 480p, and even 720p content don't look that great, everything's more soft-looking for some reason, 1080p and 4K content look awesome though. The Smart TV functionality on the Vizio is mostly average at best, while TCL has Roku, Hisense & Sony have Android TV, and LG & Samsung both have their own respective OS systems, Vizio decides to go with Chromecast-based OS system, and to be kinda fair with you I'm not a huge fan of it. It does have decent amount of apps to choose from like Netflix, Youtube, Amazon Prime Video, Hulu, Vudu, Crackle, FandangoNow, even Youtube TV is here, and among others. Anyways, I found Vizio's Smart TV system to be fairly slow & laggy but serviceable most of the time, if you're not a fan of it like me, you can always purchase a Firestick, Roku, or Apple TV for your streaming duties, I use Roku Ultra around here. When I did test out Vizio's Smartcast OS, I was shocked & very happy to see Netflix on there not only support Dolby Vision but also Dolby Atmos on content that is mixed in that immersive audio format, and surprise surprise the lossy Atmos passthrough worked on my Denon receiver, you obviously need to set the TV's audio out to "Auto" or "Bitstream" to get it going, lossy Dolby Atmos is also gladly supported on Prime Video and Vudu, Dolby Vision is present on Prime Video too. Vudu I couldn't get Dolby Vision to work for some reason, maybe it's either something I'm not doing right or maybe Vudu on there don't support Dolby Vision, Youtube HDR is also present on there too. With the exception of Netflix, I'd just stream the rest of the apps on my Roku Ultra.
So in conclusion the Vizio V-series with Ultrabright 400 and 10-12 local dimming zones is a surprisingly great TV for not a lot of money, it's never been a better time to be a videophile on a budget, recommended.
