Rated 5 out of 5 by from Awesome I brought this tv last week for my husband and I am so glad I did.

Rated 5 out of 5 by from Satisfied I have had my LG tv for almost a week now. Although i am still learning how to use all the features being i have never worked with a smart tv before i am very pleased with it! Great picture! Only problem i have run in to so far is certain shows don't cover the whole screen and none of the screen aspect ratio options fix it. Not sure if it's something i just haven't figured out yet or the tv doesn't have a setting to fix it. The zoom option doesn't do it either. Either way if that is the only problem i run into with this tv i will be happy because i can deal with that! Definitely recommend the lg! I switched to an lg phone and it's amazing as well!

Rated 5 out of 5 by from Beautiful TVs I bought two LG TVs - 43" for bedroom and 49" for living room. I love them both. Great picture, Great sound quality and easy setup. I should have had LG TVs long ago. Smart TV is spoiling me already.

Rated 5 out of 5 by from Freat Replacement and Upgrade Set We bought this set over Labor Day weekend mostly for the excellent deal at which it was being offered. 4k, smart TV features and wall-mounting were a must in replacing an older set and this one fit the bill. We are still getting used to al the features but so far we are very pleased with this set.

Rated 1 out of 5 by from TV is Nice, BUT I just bought this and it is the WORST example of a Owners Manual I have ever seen. There is basically NO INFO on how to operate your TV at all. And navigating your website is not user friendly at all. If I did not have Tech Support on the phone at the same time I would have never found any info, and furthermore what would have happened if I did not have a Computer? I'll tell you, I would have taken the LG back and bought another Brand that had directions on how to operate it in the Owners Manual like it should have. I have spent FIVE HOURS trying to figure this thig out, UNACCEPTABLE.

Rated 5 out of 5 by from Big screen great features I bought this today from Aarons and I love it the tv is huge and I can see what I'm doing I love it it's absolutely amazing
Date published: 2017-09-08
Rated 3 out of 5 by from Wifi keeps stopping, Decent UI, Great picture The wifi receiver in the tv keeps stopping. LG sent a repairman to replace all the parts and it's still not fixed, which leads me to believe it's a software issue. We gave up and ran a network cable to the tv. Cable is always faster than wifi anyway. The user interface and remote control are decent but not outstanding. The picture is great but there's very little 4K content available now. I think next time I'd get a dumb tv with a separate streaming box or Fire Stick.

Rated 4 out of 5 by from Good picture... support legs not so much! Bought this a few weeks ago, picture is good however not the brightest. Wouldn't make this my main tv but good as a secondary set for a bedroom, office etc. The con is the supplied support feet, they are made of plastic and do not fit well in the slots... not engineered very well the tv wobbles front to back and seems it could topple easy. I had to buy a wall mount, didn't trust the supplied legs.

Why can't I get a 4K signal from any of my Mac computers or PS4?  So far Im only able to view 4K from Netflix, not from any other devices.  I am using HDMI 2.0. All devices are 4K ready.  Not even my 4K camera is able to connect to this television.

I purchased the LG 43' 43UJ630 UHD TV and am considering the LG SH2 soundbar. Just wanted to know the compatibility of these two products and how to achieve best sound from the soundbar

Asked by: kribbie
Hi Kribbie. Congratulations on your purchase of the LG 43UJ630 and thank you for buying an LG. The LG 43UJ630 is not a TV model that was released in the U.S. so we do not have information on it, but as a 4K TV, it should have an Optical Digital Audio Output on it that can be connected to the Optical Digital Audio Input on the LG 100W 2.1ch Sound Bar with Bluetooth® Connectivity, Model # SH2. The issue is not one of connectivity, but more about if the Soundbar is appropriately sized for the room where you will install it. You will need to take how far from the TV you will be sitting into consideration. If you will be sitting close to the TV, then 100W may suffice, but if you're sitting further away, then you may need more wattage depending on the room size and what furnishing you have in that room, is it carpeted or are the floors bare. If you need further assistance with determining which Soundbar is appropriate with those considerations in mind, please contact your LG Support Center in South Africa^IFV
