What people are saying

Rated 2 out of 5 by from Smart TV features not working on 2 of 3 "Smart TVs We have three LG "Smart" TVs, a 43", 49" and 55", along with an LG Refrigerator, LG front load washing machine and an LG dryer. About 3 months ago the 55" TV would no longer connect with the Wi-Fi in my home. Then about 6 weeks later the 49" TV followed suit and would no longer connect to the internet. I called and after jumping through many hoops I was told that the problem was with my broadband router. I find this hard to believe since 2 lap top computers, 5 tablets and 4 smart phones all work correctly. To appease my own peace of mind I called my internet provider who advised mt that there was no problem with my modem/router.

Rated 5 out of 5 by from Picture Perfect Every time we turn on our LG tv we are amazed and happy with the clarity of the picture. We have owned this tv since 2016. The picture is as clear as the day we purchased. The set up was very user friendly. We highly recommend a LG television.

I have the app for Hulu and did download it , but wondering if it had the capability to watch live tv

Asked by: Lauralynn8
The Hulu app should have been a preinstalled app on the LG 4K UHD HDR Smart LED TV - 55'' Class (54.6'' Diag), Model # 55UH615A, but you can subscribe to and upgrade to Hulu with Live TV through the Hulu app...^IFV

Can you use screen cleaner on this tv? I dont believe it has antiglare coat, correct? 

Asked by: Tlsmit123
The screen on the LG 4K UHD HDR Smart LED TV - 55'' Class (54.6'' Diag), Model # 55UH615A is easily cleaned with a moist microfiber cloth and you can use a microfiber cloth that is moistened with slightly soapy water for more stubborn stains. You will need to check the screen cleaner that you intend to use and make sure you avoid products that contain ammonia or rubbing alcohol. Ammonia and rubbing alcohol can irreparably strip away or damage the extremely delicate anti-glare coating on the screen, which will not only negatively alter your viewing experience but also make your device a lot harder to use in strong sunlight...^IFV
