What people are saying

Rated 5 out of 5 by from 5 years old and going well. Cant' complain about this TV at all. Decent quality for the price, good menu system, and smart apps are still being updated. Nothing has gone wrong in 5 years (touch wood) and it still looks like any other modern TV thanks to fact it doesn't have a bulk frame or bezels.

Hello.  I have an LG 43LF5900-UB TV with webOS TV Version 2.1 0-3161.  I had a subscription to Hulu but when I recently tried to access the Hulu app, I received a note that said my device no longer supports this app.  Do I have any options to subscribe?

Asked by: Kllytch
If your TV no longer supports the application, there would be no way for you to force the application to be available.
