What People Are Saying

Rated 4 out of 5 by from This is my first TV purchase ever I like the size and that its smart. I just bought it yesterday at best buy. It has great picture. However, the sound is not the greatest. You can go from 0 to 100 on the volume and not hear much of a difference. I'm still learning how to configure the apps. Wish there were more to choose from. Other than the mentioned points, I really like my first television!

Rated 5 out of 5 by from Excellent value, awesome television Purchased this television about a month ago and have been impressed with the picture quality and the included features for the price. The TV includes all of the major apps our family uses - Hulu, Netflix, and Amazon prime. Additionally, we use an exterior HD Antennae for all of our local stations, which look better than Xfinity's HD broadcasts. Would highly recommend this television if you are looking to add an extra TV to a bedroom or office.

Rated 5 out of 5 by from Wonderful Wife wanted a small TV for the kitchen and this fit the bill. The picture is bright and clear and the sound is ok but would be better if our kitchen were smaller. The only trouble I ran into was getting a full motion wall mount. The placement of the cable ports caused a few returns but I was able to eventually find one that didn't cover up the ports. All in all a great purchase.

Rated 5 out of 5 by from So far so good. Have only had it for about a month now however I'm very pleased so far. Excellent picture with more than adequate sound (as least for me it is). Easy to navigate "smart TV" features. For the price that I paid I could not be more pleased, at least so far. Would recommend this product to anyone looking for a smaller TV with smart features.

Rated 3 out of 5 by from I bought it a month ago and not happy with the sound volume. I have to raise the volume almost to 100 before I have half way decent sound. Unfortunately, I wasn't able to hear it when purchasing it. Picture quality gets too light if not watching it straight in front of you. I bought it because it was on sale.

Rated 4 out of 5 by from Great TV but I Expected More The sales associate at Best Buy said I could use the TV to browse the internet with it, which would have been great since the TV was for my kitchen and it would have been great to search recipes instead of using my tablet. I see the Screen Share option but can find NO instructions anywhere to figure out how this works. So for now it's just a TV in my kitchen. I have the TV mounted on the wall but the adapter cable is too short to an outlet and I cannot use an extension cord because I don't want to see the cords which are neatly tucked under my cabinet. LG doesn't offer another power supply and I have to buy on from a third party distributor.

Rated 4 out of 5 by from Great TV for kitchen! I bought this for a new kitchen remodel and it fits perfectly in the corner. Loved that it was white which blended much better and the picture quality is good. The only complaint I have is the sound quality isn’t as good as I’d hoped. May end up getting a sound bar but other than that I’m very happy with this purchase.

Rated 5 out of 5 by from Great Choice Purchased this TV for our kitchen. It is the perfect size and has an excellent picture. Finally, it is white and looks absolutely great in the white kitchen.

How do I get the TV to connect to my speaker via BT? I don't see a BT option in the on screen display menu but the box shows that the TV has BT.

Asked by: Skip1945
You would not be able to connect the speaker to the unit via Bluetooth. The Bluetooth on the unit would be for the Miracast.
