You can finally get your hands on Vizio's flagship 2018 4K TV, the 65-inch P-Series Quantum, starting today. The $2,100 set is the company's most advanced TV yet, with 2,000 nits of peak brightness and a sleek new bezel-less design. It also packs in 192 local dimming zones, compared to 100 from the previous P-Series set. That helps the Quantum TV reach its high brightness, and it also improves contrast and black levels. In a brief demo a few months ago, the P-Series Quantum offered a noticeable improvement in image quality from the earlier line.
