4K UHD  

Ultra high-definition TVs offer four times the resolution of Full HD televisions. UHD, also known as "4K", delivers exceptional clarity and detail for all video content, even on large screens, even when viewed up close. This means you can fit a larger screen in a smaller space without compromising the viewing experience.

Wide-Ranging Color & Brightness

Color Prime Pro produces a wider range of colors for a more accurate, more lifelike picture that’s enjoyable from a wider viewing angle. With Ultra Luminance, enhanced brightness and contrast help reveal even more cinematic detail from High Dynamic Range (HDR) content.

 IPS Panel 

The IPS panel in this LG TV uses in-plane switching to deliver rich colors and strong contrast ratio that remain consistent at wide viewing angles. With IPS, any seat becomes the best in the house.

4K Upscaler  

Multi-step data analysis enhances the detail of all video content--HD or SD--to near-4K quality, delivering a viewing experience optimized for a crystal-clear Ultra HD TV.

TruMotion 120Hz

TruMotion 120Hz technology lets you see sports, video games and high-speed action with virtually no motion blur. Now your TV can keep up with your fast- moving entertainment.

webOS 3.0 Smart TV

The latest generation of LG's exclusive, award-winning Smart TV platform is incredibly easy to use with simple setup and content discovery.

Rated 5 out of 5 by from Terrific TV; except extremely poor Remote Control Screen resolution is awesome; Poorly designed remote has keys jumbled up together with lots of symbols where words are needed; Keys are very close to each other, and it is too easy to touch wrong keys.

Rated 3 out of 5 by from Great tv but has issues I bought this tv back in Oct of 2016. It's been a great tv for media consumption no matter what form. I use a Xbox One S to game and watch 4k blu-ray, Nvidia Android console for streaming games from pc to tv along with Hulu, Netflix and Vudu apps on tv. Color is great and adjustments give plenty of room to optimize for viewers (I'm colorblind) and room conditions. My only grievance - There was an update a few months ago. It has caused all HDMI input devises to have a video that constantly jumps downward. There is no problem with any of the apps for the tv. I never had this issue before and then it has only become a recent issue. I've been waiting for an update to correct this and have yet to hear back from anyone about resolving the issue. This one issue has taken a wonderful product and turned it into a mediocre product. My previous tv was LG and I'm on my 3rd LG phone. I know they can make good products.

Rated 5 out of 5 by from Vivid and Incredibly sharp picture My husband purchased this TV for me on my birthday. He already has a similar model only larger which is located in his study. This Tv is slightly smaller than his, but also much bigger than my previous TV, and it is wonderful in so many ways. The picture is sharp, the colors are vivid, the menu is easy to use, and it makes me feel like I'm in a theater. I love it. One of my best gifts from him

How can I connect the remote control to work on cable box on a 49uh6100

Asked by: Spikes
We appreciate your interest in this television. The cable box must be connected to the TV by way of a HDMI cable, in order to utilize any remote control capabilities. Once this connection has been made, run the DEVICE SETUP function in the HOME MENU BAR. This will walk you through the setup of the remote control to operate your external device.
