A year after unveiling its first 4K TV prototype, Vizio is fully commiting to the ultra high-def technology. Here at CES, the company is expanding its TV lineup to include a new P Series — Vizios first consumer-grade 4K television. Set to be in available in sizes ranging between 50 and 70 inches, the P Series, in Vizios own words, is the culmination of advanced picture quality, powerful performance and a beautifully simple Ultra HD experience. These TVs feature advanced local dimming, a backlight that consists of 64 Active LED Zones, and even Vizios very own custom silicon. Chief Technology Officer Matt McRae would only tell The Verge that the P-Series will be priced aggressively.
