Amazon offers the Seiki 39" 4K 120Hz 2160p LED-Backlit LCD Ultra HD Television, model no. SE39UY04, for $339 with free shipping. (Walmart charges the same.) That's the lowest total price we could find by $32, although we saw it for $40 less in July. It features a 3840x2160 resolution — four times that of 1080p TVs. It also has a 120Hz refresh rate, LED backlight, USB, and three HDMI inputs.
