You'll get full LED backlighting on the top two, and Razor lighting on the other.
Vizio has made a name for itself with inexpensive TVs with surprisingly good build quality, but the XVT32S is a departure. It's not that they're not well made TVs, just that they can't exactly be considered low priced.
The new XVT32S TVs are 3D ready sets that boast up to a 480Hz refresh rate, built-in Dual Band WiFi and a Bluetooth remote with a QWERTY keypad that slides out. The largest two sets in the line feature full LED backlighting with smart dimming while the smaller one uses Razor LED backlighting.
Vizio's entire XVT32S line comes equipped with Vizio Internet Apps which gives you access to Netflix, Amazon Video on Demand, Pandora, Twitter, Facebook and more. Unfortunately, none of the sets in the line come with the needed Active Shutter glasses.
The 42 inch set will run you $1,399, the 47 comes in at $1,799 and the 55 inch set sports an MSRP of $2,399.
