4K UHD Smart LED TV - 75" Class (74.5" Diag)

  • 75UH6550

Key Features

  • 8.3M Pixels for 4x the Resolution of Full HD TVs
  • webOS 3.0: The Best Smart TV Just Got Better

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.

 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 240Hz

What People Are Saying

Rated 4 out of 5 by from Love it The 4k is excellent i mount it on the wall thanks to geek squad techs i live in a townhouse so the sound is lovely and clear. But the down perk is that the remote isn't voice recognition meaning i have to buy the upgrade version remote. If people buying these high class 4k tvs shouldn't it comes automatically with the voice remote Far as that i love my 4k thanks LG

Rated 5 out of 5 by from Excellent Clarity and Features! I purchased this television because the store had marked it down as the previous years model. It is a wonderful replacement for my 70" that was my previous television.

Rated 4 out of 5 by from Excellent picture quality To be honest, I got this TV because HHGreg was going out of business & this TV was discounted over 55%. The picture quality is very good. Its a very heavy TV but I decided to mount it on the wall because my tv bracket can support up to 160 lbs & the book lists this as 85-90 but it seemed like more. The remote that comes w/ it is pretty plain but I use a Harmony so I wasn't to concerned about it. The speakers are decent but I have surround sound.

Rated 1 out of 5 by from 75" Smart Tv I bought this model Black Friday and it has been a nightmare. Getting a hold of LG takes forever, repair company slow too! Now for the second time I am with out a TV for 5 weeks and no hope in sight for the repair. I can't seem to talk to someone in America either!! Last agent was in Manila and had clapping, singing, cheering in the background the whole time I was on the phone!!!

I have 2 LG Smart TVs ( LG55UH6550 AND LG65UH6550 )....I want to buy headphones that fully cover the ears for both TVs.  What type(s) is compatible with these Smart TV models?  Is there one headphone type that can be used on “both” TVs?

Asked by: BJSS
Both the LG 4K UHD Smart LED TV - 55" Class (54.6" Diag), Model # 55UH6550 and Model # 65UH6550 have built-in Bluetooth and have been tested for compatibility with our LG Tone Series Stereo Bluetooth Headsets, however, these are not Circumaural headphones (sometimes called full-size headphones or over-ear headphones), nor are they Supra-aural headphones or on-ear headphones that have pads that press against the ears, rather than around them. The TVs do not have a Headphone (3.5 mm) jack that you can connect wired headphones to...^IFV
