Rated 5 out of 5 by from I bought this last 2yrs, May 2015.. And still I Love my LG Smart Tv

Rated 3 out of 5 by from Good picture, poor app performance I bought this tv primarily to watch MLB games and movies on Prime and Netflix . Found out you cannot change aspect picture size on the apps. Very poor tech on that. I hate watching movies without the screen filled. Unless you are lucky enough to get a jive that fills screen you can't change it. Now MLB is not supporting my tv and LG doesn't seem to be able to fix it. Get a Roku

Why is Hulu no longer supported? It was this morning, is this just some weird error?

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.
