4K-UHD LED USB 120Hz HDMI Wifi Smart

LG 55” LED 120Hz 4K Ultra HD Smart TV (Refurbished)

Stunningly detailed 4K Ultra HD resolution, which renders everything from live TV to video games in crystal clarity, makes this 55” LED TV the crown jewel of any home entertainment center. Its Smart functionality and built-in WiFi also unlock the Internet’s trove of streamable content, so movie night won’t be limited to your personal DVD and Blu-ray collection.

Smart TV: Entertainment on Demand
Stream a movie rather than walking to a Redbox, or binge on your favorite TV shows online. This Smart TV’s built-in WiFi and preloaded apps expand your entertainment options without the clutter of cables and external streaming devices. Apps include Netflix and YouTube.

Rich, Cinematic Picture
4K Ultra HD resolution supports an almost uncannily realistic picture. 4K refers to Ultra HD’s more than 8 million pixels—about four times as many as 1080p Full HD resolution—which saturate the display so completely that images retain their lifelike detail regardless of how close or far you are from the screen. This pixel density also supports heightened picture quality for non-4K content.

Clear Action, Minimal Blur
The 120Hz refresh rate delivers a picture that’s smooth and easy to follow by completely rebuilding it 120 times per second. This virtually eliminates blur, preserving a high level of detail even in fast-action entertainment such as action movies and live sports.

Enhanced Brightness and Depth
LEDs boost brightness, creating a brilliant picture that’s easy to see whether you’re curled up for a late movie or getting ready for a noon kickoff. Striking black and white levels give images more pop, contribute to a more realistic sense of depth, and amplify shadows and other lighting effects. LEDs also consume little power, making them more energy efficient than other forms of display lighting.

HDMI and USB: Connect to More Content
An HDMI port connects high-definition components such as a Blu-ray player, cable box, or Roku Streaming Stick directly to your HDTV. USB input pushes your TV’s connectivity even further, letting you do things such as view photos or listen to music saved on thumb drives, digital cameras, and other USB sources.

Great great great amazing tv and stunning picture. Only bad is having a good wall mount because the back of the tv goes inward and causes problems with the HDMI ports sticking out the back. Get a wall mount that comes further out of the wall and you'll have the perfect TV or just use the stand that it comes with.

Was delivered very timely, but did not turn on right away, unplugged and plugged back in a few times and finally got it turned on, but there was a huge white line in the middle of the screen it was flickering and not displaying picture properly. Big waste of time and it sounds like it will take about a month to get my refund.

This is my experience. I never had a 4K or smart TV before. So this review is from my perspective. Likes: Light weight, input option, has apps so now I dont need the Roku box, large enough for me to see the close caption, fits nicely into the space I have Dislikes: wish it can be brighter during the day time, the picture does not seem as crisp as I though a 4k should be - it could be a setting, Remote control slow at responding when depressing button for a command, thought the sound needed a boost so i purchased a Vizio 5.1-Channel Sound Bar with Wireless Subwoofer here at Groupon too. Overall, lots of pluses from what i had.
