The Vizio M221NV LED TV is a 22-inch  LED HDTV featuring 1080p resolution, VIA™ – VIZIO Internet Apps™,  built-in WiFi,  and Razor LED-Direct Type LED Backlight Technology.  The M221NV is one of very few 22-inch 1080p LED HDTVs on the market and can be used as a PC monitor as well.  Connectivity includes 2 HDMI inputs.

The  M221NV is the new version of  the M220NV with the addition of Ambient lighting which can adjust the pictures of TV according to the light conditions of the room.

Vizio Internet Apps and built-in WiFi allow the easy access of some of the best Internet content to your HDTV without mess wires.  Vizio streaming media includes Netflix, Amazon video on demand and Vudu video; music services such as Rhapsody  and Pandora.  However, there is no Youtube and it does not offer streaming of your own music, photos, and video via a home network (DLNA) or USB stick. Vizio says it will add this function during the holiday season of 2010.

Vizio apps include Yahoo widgets, Facebook, Twitter, Picasa and Flickr, Weather, News, Sports and Stocks.  But it does not have Skype.
