Rated 4 out of 5 by from So far so good I purchased this TV about a month ago and so far I like it, plus the price was right. I'm still learning about some of the features, but it's definitely a lot better than my old set. I am not thrilled with the legs the TV sits on, so I ended up purchasing a third party stand that is a lot better.

Rated 3 out of 5 by from picture fine Everything is good except at least once a day on start up the picture and the audio will go on and off. If I shut it off and restart it the problem will go away. I'm sure theres a problem but its sporadic.

Rated 5 out of 5 by from Great TV Features I bought this TV when my old flat screen went bad. The picture quality is great. The smart TV hookup allows me to use the 5G section of my router allowing a much better smart tv experience. The tv audio is better than the salesperson indicated. I get all the volume I need. The price was very competitive.

Rated 4 out of 5 by from Just as advertised I bought this to replace my older TV and it's perfect. Lightweight, picture quality is great, and price (on sale) was a steal. I'm in the process of moving so haven't got to use it much, but so far it's like the reviews I read. 4-5 stars!

Refresh rate is 60Hz and the specs also indicate Trumotion 120. What does this mean? For fast moving sports will there be bluring?

Asked by: RLRs
The LG UK6300BUB 4K HDR Smart LED UHD TV w/ AI ThinQ® - 50" Class (49.6" Diag), Model # 50UK6300BUB has a refresh rate of 60 Hz which is how often the TV changes the image on the screen, in other words, the number of frames that the TV can show per second. This is measured in Hertz which is a unit of frequency. Trumotion is LG's name for motion interpolation which is a feature that increases a video's frame rate, usually up to the maximum frame rate of the TV. It has the effect of making movements look smoother, clearer, and more lifelike than what you typically see from movies and TV. This feature only matters if you want to be able to make movement in videos look a bit smoother...^IFV

Hi. We bought this TV because it promised to work with Alexa. It barely works with Alexa, on a good day... Can you please improve the Alexa skill so it works? And add the ability to turn the TV on with Alexa?

Asked by: cloudberry
Unfortunately, Power ON does not work with Amazon Alexa. Only Power Off. Also, we have a lot more functions that work with Alexa compared to other manufacturers and it should improve as time goes by. ^AC
