Walmart offers the Seiki 50" 120Hz 4K2K 2160p LED LCD HD Television, model no. SE50UY04, for $449 with free shipping. (Newegg charges the same.) That's the lowest total price we could find by $99, although it was $20 less three weeks ago. It features a 3840x2160 resolution — four times that of 1080p TVs. It also has a 120Hz refresh rate, LED backlight, and three HDMI ports.
