This got good reviews from rtings.com so I stuck one in the cart. Wanted to double check the Hdr it uses so did a quick search. It’s Dolby Vision. While searching I found that Costco has the new, non-refurb (full warranty from Vizio & includes an extended warranty to the two years as well) for $799.99.
