Walmart offers the Sceptre 49" 4K 2160p LED-Backlit LCD Ultra HD Television, model no. U500CV-UMK, for $449 with free shipping. That's tied with our mention from three weeks ago and $58 below the lowest total price we could find for a similar Sceptre Ultra HD television, although we saw this model for $50 less on Cyber Monday. This Roku-ready TV features a 3840x2160 native resolution (four times that of 1080p TVs), LED backlight, USB, and three HDMI inputs.
