About LG Electronics 79UB9800

The LG 79UB9800 79" Class 4K Ultra HD Smart 3D LED TV lets you enjoy stunning 4K resolution on the big screen. It is equipped with the exclusive Tru-ULTRA HD Engine Pro, which upscales SD or HD content in lifelike, near-Ultra HD so everything you watch will be enhanced.

4K Resolution
ULTRA HD is a new standard in picture quality and it's the future of high-end video display in the home. The resolution is four times that of Full HD 1080p, with a whopping 8.3 million pixels to display flawless images, even when viewed up close. Enjoy incredibly vivid colors and picture details as never before.

IPS Panel
One of the secrets behind LG TVs outstanding high-definition performance is the specially designed TV panel. The quality of the panel helps determine the quality of the picture and the IPS (In-Plane Switching) panel makes any seat the best in the house, with a clearer and more consistent image at wide viewing angles compared to conventional screens.

Tru-ULTRA HD Engine Pro
Enjoy the benefits of 4K resolution today. LG's Tru- ULTRA HD Engine Pro upscales the picture through a 4-step data analysis that enhances the details of broadcasts, movies, sports and videogames to near-4K quality, giving you the superior viewing experience you expect from an ULTRA HDTV.

HEVC Decoder
The recently developed HEVC (short for High Efficiency Video Coding) compression format is essential to ULTRA HD/4K content playback. Some next generation content will use this HEVC format and this TV has it built-in HEVC decoder to display the 4K content.

LG Smart TV
LG Smart TV makes it easy to connect to premium content from providers like Netflix, Hulu Plus and YouTube. The simple and fun Magic Remote saves time and trouble, letting you point, click, scroll and even speak into the remote to find exactly what you want, searching across apps, movies, TV shows and the web... all at the same time!

And now you can control your compatible Blu-ray player, home theater system, set-top-box and sound bar with just one remote. Spend less time navigating and searching for remotes and more time enjoying your entertainment.

Great value

Excellent image and sound quality. Magic mouse makes using Smart TV features very easy. It is the best I have seen. Skype speed is bit slow. It is missing HBO-GO. Voice commands do not work well.


Most Liked Negative Review


Great 4k up conversion, but poor ghosting on 3d

This is a great TV. Tremendous up conversion. My challenge is that we have quite a bit of ghosting with the 3D. With such a large picture, the ghosting really becomes a distraction and there is no where I can find in the 3D setting to adjust this. For a TV of this price, I wouldn't have expected this type of set-back (I have a smaller LG 3D TV with no noticeable ghosting).

Amazing TV


You will not regret buying this TV, it has an amazing picture, even over the air HD looks great. I have owned several LCD/LED TV's and this is by far the best. I had read the reviews, watched several youtube comparisons, in store demos, and was ready to buy, but was still uneasy about spending so much on a tv without seeing what everyday non 4k looks like and 3D. I found the 55in LG 4k at a warehouse store for a great price and replaced my familyroom tv. My rational was if I did not like it could be easily returned and I would look for another tv. I was amazed by the 55 in, 4k is stunning, 3D will wow you, everyday HD from Satellite and over the air is fantastic. Needless to say after a few days with the 55in I went out and purchased the 79in, now I have 2 great tv's. The interface for the tv is easy to navigate, I was a little worried about the remote, it is like a Wii controller you move the pointer to get to menu options etc. It will also allow you to click through options and screens with remote buttons, both ways are easy to use. Never used the smart functionality of a tv, I always found the interface to be clunky and slow, would use an external device like a gaming console, not so with this tv, it is easy to use and fast, can switch from netflix to Hulu to youtube and back easily. There is voice and gesture motion control for this tv as well as a built in camera (have not used Skye yet) Sound is very good from the built in speaker bars, surround mode gets me every once in a while, most with water features in a movie or show, I think for a second that there is water running somewhere in the house. Could babble on for days, I cannot not say enough good things about this tv, it is an outstanding value, many cool features, amazing picture and 3D. This TV will be the showcase of any room and will not disappoint.

Fantastic value in a 79' HDTV


We couldn't be more pleased with out purchase of this big screen TV. Out of the box, the settings are way too bright. Once toned down, the picture with an HD signal is fantastic. No issues with high speed action such as sports. What little 3D we have tried looks good as well. The speakers have only been used when we have watched a little on-line content. They sound as good or better than any sound bar we have tried. Another plus is side view quality, great when we entertain


Excellent TV for the price


This was my first LG purchase and have been completely satisfied with the product. Excellent picture and easy to navigate through the menu. Love it!! Pat


Fantasic picture, easy to use


This was an upgrade from a 65" rear projection tv. It is a whole new world of enjoyment. Great picture in all modes, the built in sound is better than most. I have it paired with a 4k upscaling dvd player and all my movies look so much better. Can't wait for baseball season to start. Only negative, you can't use wireless headphones and the built in speakers together. I am hard of hearing and really like using the headphones, my wife would rather just have the tv speakers on.


yes i like very very ,

Great Value for an incredible, huge display


We are big NFL fans and watching NFL Sunday Ticket on this huge TV with incredible resolution makes you feel bruised and tired when the day is over. Watching movies is like being at the movie theater only with much better resolution. TV also has a tremendous built-in sound system. Really considered disconnecting my surround sound system it is so good.
