Rated 2 out of 5 by from ?smart Bought this TV and placed in a spare bedroom, recent guests have told me this isn't a smart TV as there are no Apps loaded and no way to access the WebOS system from remote. Our college age son came home and said only way to get Internet and stream a show was through Playstation or his Firestick. This really really upsets me as we paid a premium when this 4k Smart TV first came out. I wish I had known this earlier as I would have returned it as its apparently been either falsely advertised or I received a lemon or perhaps the wrong remote. Otherwise it has a good picture and was working through our Cox Contour box (we've recently discontinued.) which is why im just learning of the problems. I bought the same version LG 65" with magic remote the same day and enjoyed it until it apparently suffered a power surge and no longer works:( It would be great to get some customer service explaining the problem and a resolution. I purchased another LG 4k Smart TV to replace the 65" but this time paid for the 5 yr full coverage...No more excuses or frustrations I hope. Mark

I have an amp with hdmi pass through, does this tv (49uf6400) support it? Also, is the arc input a 4k input also? Or is the arc input only 1080?

Asked by: loganmay9
HDMI Pass-Through is not a feature that you find on TVs. It is a feature that passes video and audio signals from a High Definition (HD) source such as a Blu-ray player or a HD Set Top Box to a Home Theatre System (HTS) via a HDMI cable. The Home Theatre System plays the audio from the HD source through its own speakers and sends the unaltered video signal to a TV via a second HDMI cable. A Home Theater System that supports HDMI pass-through will have one HDMI OUT port to send the HDMI signal to a TV, and at least one HDMI IN port to receive a HDMI signal from the connected external device. If your TV does not have HDMI Out, pass through can still be configured by using HDMI ARC (Audio Return Channel) port or an Optical Cable connected to the TV's Digital Audio Out port going to your HTS Digital Audio In port. ^AC
