What people are saying

Rated 5 out of 5 by from Great TV I've had this TV for YEARS now. In fact I bought two. One for guests in the loft and another for my bedroom. Both t.v.'s have been great. Apps load fast, picture is great. The price was pretty low, I didn't know what to expect, but this t.v. has exceeded all my expectations!

Is Hulu still supported on the 55UF6450? I used to be able to watch and now the app is gone from even the LG store. What happened?

Can I download sling or direct tv now or philo on this Tv?

Asked by: Robinson1020
Compatible LG Smart TVs come with Sling TV pre-loaded on the webOS launcher bar once your Smart TV is connected to the Internet. LG Smart TVs using webOS 3.0 or higher support Sling TV and on those TVs that do not come with Sling TV pre-loaded, you will need to search for it by pressing the Home button on your remote, then selecting LG Content Store > Search and entering "Sling" using the on-screen keyboard to download the app and install it on the TV. Regrettably, the LG 4K UHD Smart LED TV - 55" Class (54.6" Diag), Model # 55UF6450 uses webOS 2.0 and is not compatible with the Sling TV app...^IFV

What is the input lag time for the uf6450

Asked by: Randy5000
Hi Randy2018. Regrettably, Input Lag is not an official television specification and you typically will not see it listed for TVs because it is the amount of time that elapses between the picture being generated by a source and for that image to appear onscreen. So it will vary according to the source and to the TVs settings. The results for Input Lag will also vary according to the which Input Lag Test Method is used. You might be able to find reviews online who have tested the LG 4K UHD Smart LED TV - 55" Class (54.6" Diag), Model # 55UF6450 for Input Lag and posted their results on their sites while identifying which Input Lag Test Method they used. However, keep in mind that this is a 2015 model so reviews for that TV may be hard to find...^IFV
