Full-array LED backlights, 240Hz, and Internet apps - Vizio

Vizio, which is gained a foothold in the U.S. TV market with low-priced basic HDTV models sold mostly through warehouse clubs such as Costco, is now shipping its XVT series of 1080p LCD TVs. These sets offer step-up features, such as full-array LED backlights and the Vizio Internet Apps platform, at prices lower than most of its competitors.

Three larger-sized models the 55-inch XVT553SV, the 47-inch XVT473SV, and the 42-inch XVT423SV—use full-array LED backlights that have more zones that can be locally dimmed than previous models. By enabling some zones to be dark while others remain illuminated, local dimming can help improve black levels. Other features in these sets include Vizio's 240Hz technology, and it’s VIA online service, with access to streaming movies from Amazon, Netflix, and Vudu, and the Rhapsody music service.
