If you want Vizio's 4K TV with SmartCast 6-inch Android remote, Ultra HD with Dolby Vision HDR and Google Cast receiving but you're not ready to pony up for a high-end P-Series set, a cheaper version is now available. Vizio announced the refreshed-for-2016 M-Series line in April and now they're going on sale, first via Vizio.com and eventually through other retailers. CTO and head of marketing Matthew McRae says that larger 70- and 80-inch versions are still on the way, but currently the $850 50-inch is the easiest one to get. Vizio:
