What people are saying

Rated 5 out of 5 by from excellant choice chrisp, sharp , vivid picture.added LG sound bar and woofer to enhance the experience

Rated 1 out of 5 by from Poor Quality - Screen Issues After 1 Year I purchased this TV after reading decent reviews and seeing a great demo model on display. We started having problems with it after barely owning it a year. The screen started going darker, with blacks and blues invading the screen. Attempts to recalibrate and to replace high-end HDMI cables were unsuccessful. LG offered no support beyond having me reach out to a technician for a full cost repair. After researching online, I found that this is a common issue with the cheap video boards that LG installed in this TV.

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
