Nice picture good design.

shaidar007 10/12/2018

Ive had this TV for the better part of a year and Im still excited about it. The main thing that separates this TV for some cheaper models is the increased NIT output. Combined with local dimming this makes for a vivid brilliant picture with blazing light when appropriate and blacker blacks than most IPS screens Ive seen. 4k programming is absolutely stunning on this TV. One word of caution: There are so many features and settings it can be a little overwhelming to the point that it is now common that people hire a professional to tweak the settings. Improving and adding detail to the tooltips for each setting and function would be quite helpful for those of us who would feel silly paying someone else to play around with our TVs.

Excellent for our needs.

2jan 9/4/2018

We bought the LG 55 screen tv in January. In the beginning it was a daunting prospect for my husband and me almost 80 years old to set up this new digital technology - a smart tv for us?? Our daughter said Mom you didnt buy a smart tv did you? We tackled the task and within two days figured out how to hook it up use our smart tv even learned how to use our Roku stick with it hooked up our DVD/VHS player connected our external antenna box for local channels and programmed the tv for those channels and hooked up our computers using HDMI connections. We didnt have to call for help because the instructions we had and the online directions made it possible for us somewhat technologically experienced seniors to hook up a smart tv. Thank you LG for making it possible for us to enjoy smart tv in our home - since our grandson decided to take back his 50 tv back when he finished Marine boot camp.

Smart not to Scary

IraGlen 8/8/2018

Had this for a couple months now... we are an older couple which we were concerned that it would be hard to use understand... just the opposite very easy to use and control... extremely happy ... Plus you bonus channels on the webOS system. 1 complaint.... the magic remote will not control my set top cable box. It is on the list .. Entone brand Cincinnati Bell but will not change channels etc... but my set top controller will work the TV... but it eliminates the magic remote which I really enjoy using

Ease of setup/Quality features

rwz01 8/3/2018

I bought my 55UJ7700 a month ago. My previous couple TVs were big name. After the same problem happening with both of those I opted to go with LG. I am very satisfied with the ease of setup and the features it offers. The quality of picture is great. The sound is not exceptional but I take it through a receiver so that becomes irrelevant.

55UJ7700 Review

Lee N 7/18/2018

After doing quite a bit of research I chose the LG 55UJ7700. It was not the cheapest TV out there but very competitively priced. After having the TV for over a month now I am very pleased with it. The quality is outstanding. The only downside is I am having a hard time connecting my smartphone to it which is coincidentally a LG V30. Other than that I am completely satisfied and would highly recommend this TV to others.

Wookieman 7/15/2018

I really like the WebOS that my LG TV has it makes using and finding my smart functions very easy. I also really like the magic remote. I do feel that the picture is darker than the Samsung I had previously even when on the brightest setting it is taking some getting used to. Overall it is a nice TV.

Has a sleek look which adds on to our living room nicely and the picture quality is unbelievably incredible. We couldnt be happier.

The future of TV

Zeusbap 6/7/2018

Weve been using a different brand TV for years and changed to LG because we heard about how great the UI was. Turns out thats wasnt all this TV is great for We were pleasantly surprised to find the package came with an LG magic remote which makes our customizable Harmony One a thing of the past. Weve found that the one remote can do it all Combined with our SONOS sound bar and the full LG navigation screen we have ditched all the receivers Apple TVs and Blu ray players for just the magic remote and TV We love it.

I purchased this tv as the first piece in my new home. As this is my first home as the homeowner I wanted the very best and I was not let down I would recommend this product to my family and friends. The sound is fantastic I did purchase the sound bar to accompany it-yet even without the sound bar it is on point. I used the tv without the sound bar for a month before installing the sound bar. The graphics are out of this world The visual image I am able to get with this tv is perfect. When movies or tv shows go dark I can see everything in perfect detail unlike my last tv-or many TVs my family and friends have . I am truly happy that I made this purchase and will be making another

Great picture nice remote.

FBinCA 4/5/2018

Worth the upgrade that one level higher will last through the next generations of 4K content as it becomes industry standard. I like the magic remote but wish it were programmable for IR signals. However Im sure other components like my XBOX One will eventually receive software updates or be swapped out and my whole entertainment ecosystem will have the HDMI CEC throughput. The dream of having only one remote is not far off. No Im not going to buy an overpriced Harmony. Overall this television has the superior picture quality and clear sound that youd expect as well as being aesthetically pleasing. Note: Out of the box settings need some fiddling and there are quite a few websites out there to give you tips on what to do. When dialed in though this TV is pretty amazing.
