Exceeded all of my expectations

rebecca498 9/25/2020

Its very hard to overstate my satisfaction with this TV. Im not one for hyperbole but this TV is AH-MAY-ZING. We thought we had a pretty nice TV before but its been a transformative experience getting to know this awesome piece of technology. First the size of it even though the TV is a massive 77 inches because the actual thickness of the screen is less than half an inch it is still light easy to maneuver and sits snug up to the wall. There is also the option to have it standing in which case there is a weighted base to balance. This is the perfect TV for movie night because we can sit a bunch of people all around the room and there is a perfect view from any angle The picture quality this is why you buy this TV. If youve never watched on an OLED screen youre missing out big time Without getting too technical but look it up its so interesting the picture quality of the Organic LED is unlike any top quality TV screen Ive seen before. Its ability to bring vivid colors blackest blacks brightness in the dark scenes clarity detail and more has blown me away. I watched my favorite sitcom series and noticed the tiniest things in the background that Id never seen before. I marvel at how the screen clarity makes shows look like big budget films. It literally feels like youre in the scene and on set. Connectivity This Smart TV has become a hub for all our smart tech in the house. Not only is it fully connected to the internet we could browse all day laying in the recliners LG has an app for our phones to connect and control everything and it makes being in charge of it all from anywhere so simple. The TV comes pre-loaded with most popular apps but LG has a suite of popular apps Netflix Hulu etc. as well as some original ones that you can download directly to the TV. Switching between apps is very easy just a couple of clicks on the smart remote. Speaking of remote Ive never had a remote that I could speak to- thanks Alexa- or that can be used as an IR pointer to point and click at things on the screen. Its really just fun to use One of the cool things is the art screensaver feature that makes the TV look like a giant framed art piece on the wall. The set-up and installation of the TV was easy enough for us to do ourselves. We got it working within minutes at first it was difficult to connect to LG but connecting an ethernet cable fixed the issue. Working perfectly ever since

Unbelievable Picture

goofyguy91 9/7/2020

This is without a doubt the best TV that I have ever owned I was only replacing a LED tv that was a little over a year old with what I thought was all the bells and whistles but it doesnt compare to the quality of an OLED TV. The problem Ive had in the past is figuring out the perfect calibration for a new TV but this LG TV came with a couple of perfect picture modes right out of the box depending on what type of content you are watching. Following the super easy setup and installation not having to mess around for hours on perfecting the picture was a blessing. The remote is easy to use and was able to connect to my existing sound system and control my Fire Stick. We are currently using the Fire Stick for most watching but using the built in apps work just as easily. Theres even a cool feature that allows you to pick your favorite sports teams and get score updates as you wish that pop up in the corner. Just one of many cool features and apps available. Another part of this TV that just cant go unmentioned is the overall style and look of the TV. It was super thin bezels and of course its about as thin as you could imagine. Only thing I wish was different is where I have it set up so you can fully appreciate how thin it is. Back to the quality of the picture I have to mention how good it does in both dark and light scenes. Ive had problems with blooming and banding on other TVs but none of those problems exist on this set. The OLED pixels allow the picture to get pitch black in dark scenes while still keeping the contrast and see all the details in the scene. Nothing gets lost. In all I would definitely recommend this TV to anyone who is looking for the perfect set for any type of viewing. Cant be beat.

Worst screen Burn in TV was dead

Palu12377 7/30/2020

The TV I bought resulted in burn-in within months even though the viewing is only netflix prime video. Also the viewing is normal usage with 3 hours usage max. The TV is also dead since the power keeps on off often and finally the TV is dead. Customer support is also very poor.

Picture and sound are great but no Google apps?

mariner8993 6/2/2020

We bought this TV of course for the amazing picture and smart applications especially because of the availability of google asst built in. What we didnt recognize with this model confirmed after 3 phone calls and 3 online chats with customer and tier 2 service was that the Google home and Google Asst apps would not work on this model television. Very strange why it wouldnt work on the brand new 2020 model with a WebOS of 5.0 but it worked on previous models. Weve spent hours talking to LG reps trying to figure how how to connect our Google Home and Google Nest to the TV with no luck. We watched numerous YouTube videos showing people just clicking on the Google Home app on the TV but these were all on the C9s and not the C10s. Weve reset to factory settings registed the TV with LG downloaded and tried to link through the LG ThinkQ app on our phones with no luck. LGs Tier 2 customer service kept telling us to go into settings and click on Link to Devices using voice commands but there was no such setting on the TV. Unfortunately we will probably be bringing the TV back which we had to rent a U-Haul for. We were hoping to be able to live stream our Google Nest cameras directly to the TV instead of using a screen share app. Either that or we have to utilize a chromecast which we currently use on our old TV. But we paid a lot of money for new technology that just isnt there. Why make a new model that does not support previous apps???

Amazing TV

Roning 5/24/2020

The colors stand out and very close to reality a sharp image with the most impressive clarity Im in love with this screen. The HDR 10 and the Dolby Vision absolutely AMAZING You will get the wow effect every time. And of course the WebOS new features are great and useful. This is the best O/S for the TV.
