Walmart offers the refurbished Vizio SmartCast 55" 4K 2160p WiFi LED-Backlit LCD Ultra HD Home Theater Display, model no. E55-E1, for $379.99 with free shipping. That ties our mention from a week ago and is $170 under the lowest price we could find for a new unit elsewhere. It features a native resolution of 3840x2160 (2160p), Vizio SmartCast technology with integrated Google Cast, USB, and four HDMI inputs.
