What People Are Saying

Rated 5 out of 5 by from What you would expect of such a tv at this price I just bought this tv a few days ago and let me tell you its the real deal. I was waiting and waiting for the right time to dive into the 4k world and I'm glad I waited for this deal. I picked mine up at Costco on sale and I don't regret it all. The picture is clear and the movement of the screen is smooth as can be, this is by far the biggest TV I've ever owned and This one moves even better than my 120hz 55 inch. Just a high quality TV all the way around. The one thing you should expect when getting this TV is that you need to tune it! It's not going to come out of the box anywhere close to the display you seen it on. Just takes some time is all, first thing you do is take it out of energy save mode, that seems to help a huge amount. But like I said take the time and adjust the screen to the room and to your liking, you'll find it's highly customization and the sound on this thing is truly impressive. I'm glad I picked this one up

Rated 2 out of 5 by from Audio Video Sync Problems had to return the first one for picture sound sync and the next one had the same problem. Changes cables - cable supplier box. Settings will not solve the problem either. Picture good - I called support and a tek came out to my home but could not fix it. Also no magic remote is available for that model yet.. strange

Rated 4 out of 5 by from Great family viewing The TV is big enough to make you feel like you're part of the action on the screen. The users guide, however, is probably Ihe worst one I have ever seen. It is difficult to navigate,difficult to understand, and difficult to find what you're looking for.

Do I need a 4K hdmi for this tv? 

Asked by: Tyorsini6
There are only four kinds of HDMI cables for the home: High-speed with Ethernet, High-speed without Ethernet, Standard-speed with Ethernet and Standard-speed without Ethernet. High Speed HDMI cables haven't changed in years and there's o such thing as an HDMI 2.0 cable. The version numbers refer to the HDMI connections in your gear. Which is to say, your TV can have HDMI 2.0 inputs, but your HDMI cable is just an HDMI cable. Any High-speed will do for the LG 4K UHD HDR Smart LED TV - 75" Class (74.5" Diag), Model # 75UJ657A...^IFV
