5.0 out of 5 stars Extremely satisfied

Updated review (10/13/2020)

Mounting was a breeze. Took about 10 minutes to screw the mount into the back of the TV. Most of that time was ensuring that I attached to the desired holes on the mount, as the mount supported attaching the TV at multiple locations. It does take 2 people to mount. I don't care how strong you think you are. It's not a weight issue so much as it's a wingspan issue. The required placement of your hands, so you don't damage the EXTREMELY thin screen, doesn't allow for only holding the entire TV with 2 hands. I solicited the help of my visiting in-law. We picked it up, hooked the mount to the wall and presto we were done. Plugged in the power and cables and ready to watch.

Recommendation: Pay the extra money and get an AC outlet directly behind the TV. They sell power cable in-wall kits that don't require an electrician and I'm sure those work just as well. Basically those are just cable routing outlets that allow you to use an electrical extender to bring power from the outlet behind your ground-level furniture thru the wall up to the extension "outlet". It's cool because it's really just a fancy extension cord so you aren't faced with the cost of an electrician to install a new outlet. Point is...get an extender or a new outlet. Either way you're not going to want to see cables dangling down the wall after mounting your beautiful, expensive TV. I had to get a real outlet installed because the wall I mounted on was an outdoor perimeter wall, so the thickness between the dry wall and the concrete block left about 1.25 inches of space. My electrician had to feed the cables thru the wall until his hands were bleeding (better him than me) as the space was so small. The wall mount had to be drilled thru the drywall directly into the concrete also. Upside, that TV is never falling off the wall. I could hang 10 TVs off that mount. I jest.

Also I bought an LED strip that is stuck to the back of the TV. It plugs directly into the USB input on the back of the TV so it turns on/off with the TV. You can change the colors but I just go with a soft white and it really compliments the TV and provides an outer glow which can be seen in my attached photos.

Original review...
Everyone talks about the amazing picture quality so I won't bother with that. Let's just say it's incredible.

Something that really impressed me is the thickness of the actual screen. It's thinner than my iPhone X. The "downside" to the screen being this thin is when we lifted it I was concerned about applying too much pressure and potentially causing damage as it flexed. The instructions discuss how to hold the TV when lifting it whereas most of the pressure is actually to the bottom half of the TV so it isn't really a problem but something to be cognizant of.

It's easy to access all the inputs/outputs on the back. 4 of the HMDI ports are actually on the left side (facing the TV). The power cord is on the right side, although rear facing. That's not a complaint, I just want to provide that information.

Setup couldn't be easier. I had my cable box connected thru HDMI and my PS4 connected thru HDMI as well. Then I turned on the TV for the first time. Over the course of a few minutes the TV detected everything that was plugged in and asked a question "are these the correct components plugged in?" Aside from providing the wifi password I didn't have to get involved in the setup at all. After everything was setup I plugged in my Bose Soundbar. I tried using the HDMI eArc plug which failed as it always has (same lack of success on my previous TV). I've come to the conclusion that the only way to get the Bose Soundbar to work is thru the optical cable, and I don't put the blame on LG. That is certainly a Bose shortcoming. Regardless, I plugged it in thru the optical port. You have to navigate to the "All Settings" menu thru the TV to the sound settings. There is a selection to use Optical, TV, Both, etc. When I made the correct choice it worked as expected.

The TV also comes with an over the air LG TV service. That was completely unexpected. I confused that with the cable provided by my Spectrum cable box. Once I realized what was happening I was pleasantly excited. I don't know if I will use it, but considering the cost of cable it is something I will investigate further.

We had the Amazon Fire TV on our older TV and don't need it anymore on this new TV. All those same services that we use, Netflix, Amazon Prime, Apple TV, Disney Plus and Hulu are built in. As expected an enormous number of other services are also available. That is very convenient.

In conclusion I recommend this TV purchase with zero hesitation.
