Rated 5 out of 5 by from Awesome viewing experience What can I say? I studied this tv and one of LG’s competitors for a month. Then out of loyalty bought the 75 inch LG. And ohh boy am I glad I did!!! This tv is sooo clear it’s as if I’m sitting in the middle of the football field in the huddle with the players!!! I could NOT have made a better choice.

Rated 4 out of 5 by from Great for the price, but HEAVY This was purchased to replace an old style ceiling mount projector putting the image onto a reflective pull down white screen on the wall. This is strictly for business presentations. The image was just too blurry. The intelligent setup was very good. I looked all over the packaging for a total weight and never found it - just an icon of 2 people lifting it. I'd guess it was around 95 pounds. The packaging was so big I had to use a trailer to get it to the office, then press 2 strong young men to lift it up onto a counter top. I should have expected that, but I've never has a TV that big before. Works flawlessly, great image even from the side. Even if we used it for movie watching it's still far better than my personal 32" Sony Bravia.

Rated 5 out of 5 by from Worth The Wait My husband and I have been wanting to purchase our first flat screen television for awhile now. As we saved for it, we researched and looked at different ones in stores. We finally decided now was the right time and LG was the right one for us. It was well worth the wait. We both love it.

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
