What People Are Saying

Rated 5 out of 5 by from Better Than I Anticipated I recently bought the LG TV with WEBOS and after even one day I've been greatly impressed with the features. I plugged a USB dongle in for my wireless keyboard and mouse and was surprised how well they work instead of using the onscreen keyboard and remote for web searches. Also impressive is having the TV channel I'm watching in a picture in a picture mode while browsing the web. Great Job LG with this model. I may even replace all my TV's with new LG WebOs units soon.

Rated 4 out of 5 by from Great picture The picture quality is really good. It's a big step up from my previous TV. I had no problem removing it from the box and getting it hung on the wall. I'm still learning new things about my TV. The only gripe I have is that I can't find an option to turn on "wireless sync" in the sound menu. All of the information I find on the internet, says there is an option.

Rated 5 out of 5 by from Life is Good with Great Resolution & Appreciation The LG 49UJ6300 49" UHD TV is unique and noteworthy. It brings to life in one's home the audacity of life, it's vitality and essence. The colorful vision and intricacies in detail reflected on the screen in HD especially 4k depict this view and truly appreciated resolution. Our world is more admirable and appreciated especially the natural and scenic places travelers are anticipating with delight to see before they die. TV shows and both national and international programs watchable on the screen are now more breath-taking and appreciable. All in all it is a truly wonderful experience as one can appreciate greatly what one sees.

Rated 5 out of 5 by from Very Nice This is a very nice unit. The software for streaming works well. Available ports were adequate for my outboard multi media connections. Only disappointment is that the LG screen casting app is terrible, really not useful at all.

Rated 4 out of 5 by from Reliability a concern Beautiful picture with stunning colors. Let's hope this second one lasts longer than the first one, which only lasted a little over a month. The picture developed a horizontal line across the whole width of the picture. Had to return the first one to Sam's.

Rated 1 out of 5 by from TV did not work out of the box Just purchased the tv and set it up. The tv is stuck in factory. After an hour of trouble shooting and waiting on hold, LG said they would have to send a technician out to try and repair the TV. Should not be an issue this is poor quality. I am going to try and return the TV for a brand that actually works. Very disappointed with TV and the time I wasted setting up and trying to fix.

How do you hook up the Bluetooth for the speaker

Asked by: Starr417
This unit does not have Bluetooth, if you are referring to a soundbar, the main unit of the soundbar would connect to the TV via Digital Optical Cable. ^AC

Is the 43UJ6300 able to use a keyboard? Can I buy a after market keyboard for this TV or do you offer such a device?

Asked by: Ewoot
LG has several Bluetooth enabled TVs that have been tested for compatibility with the LOGITECH K360, LOGITECH K400, LOGITECH K750, and LG Electronics MKS-1200 Bluetooth Keyboards. Regrettably, the LG 4K UHD HDR Smart LED TV - 43" Class (42.5" Diag), Model # 43UJ6300 is not a Bluetooth enabled TV...^IFV

Hi is this a 3D tv also?

Asked by: Dfreshone1
The LG 4K UHD HDR Smart LED TV - 49" Class (48.5" Diag), Model # 49UJ6300 is not a 3D TV and none of our 2017 TVs are 3D TVs. The "J" in the model numbers identifies the TVs as being 2017 models...^IFV

Are you able to connect Bluetooth ear buds to this TV or does it require an adapter?

Asked by: Bobbitt15
The LG 4K UHD HDR Smart LED TV - 65" Class (64.5" Diag), Model # 65UJ6300 does not support Bluetooth. There are adapters available that you are supposed to be able to connect to an audio output on the TV that will allow you to pair Bluetooth Headsets to the adapter so you can stream audio from the TV through the adapter to the Bluetooth headsets. The only audio output on the TV is the Optical Digital Audio Output. LG does not make such adapters and most of the ones available online require an Analog RCA Stereo Output (Red/White barrel ports). If you can find one that has an Optical Digital Audio Input that you can connect to the TV's Optical Digital Audio Output, it might work. You'll need to refer to its instruction manual or check with its manufacturer about its capabilities and compatibility with non-Bluetooth TVs...^IFV
