After first surprising consumers and competitors with their then excellent first edition P-Series 4K full-array LED backlit 4K TVs in late 2014, Vizio went on to release several new 4K TV editions for 2015 and now 2016, all of which were good to great. The 2015 D-Series 4K TV models and M-Series TVs have now also joined the 2016 P-Series second edition 4K HDR TVs to also be re-released with a completely revamped smart TV system and with the addition of some rather excellent HDR technology for expanded color and contrast quality which completely outdo what we saw in the 2014 and 2015 versions of these TVs.
