Absolutely Stunning

ceastman17 10/16/2020

This TV is amazing The panel is the size of a wall I ended up placing the TV in the living room for all to see its like a center piece of my home The immersive blacks and sound quality are unreal Im definitely eager to get the soundbar to take the cinematic experience to the next level This TV is perfect for streaming and gaming. The gaming capabilities are unreal GSync and Nvidia makes this TV ready for next generation consoles. Having Google and Alexa built in are great all the streaming apps load quickly and the movie mode is excellent. Definitely future proof and worth the investment. I received this product at a discounted price in exchange for my honest opinion

Apps stop working o LGTVs

Chuck1967 10/10/2020

There are constants issues with my all of my LGTVs with running the YouTube app. After readimg how to fix the issue everywjere and not fixing the issues I find out that this s a common issue with LG and the YouTube app. So if you are a big YouTube watcher I would purchase another brand. Ill never buy an LG product again after readimg everythimg I did about their TVs.

Best TV out there at the moment

ztru 10/9/2020

The good: 1. The picture is unbeaten out there on the market. It takes a bit of setting up to get the perfect picture for what you are watching but once you do you will see one of the better TV pictures you have ever seen. It does Dolby and HDR beautifully and it almost looks too real sometimes when watching nature/HD content. 2. The shape of and overall style of the TV is beautiful. The bezels around the side are super small so it looks like the picture on the screen goes to the edge of the TV. The stand is also very sleek and it the shape of the stand is very clean. The TV is also super thin and would look great mounted as it wouldnt come out too far from the wall. The So-So: 1. The TV comes with a great remote but the initial setup of the TV remote has a motion activated mouse button that is a little difficult to get used to and is activated sometimes by accident when moving the remote. It does offer a lot of buttons and has voice control as well. 2. The TV is loaded with LGs software and offers a ton of apps you can download and use easily. Although it does have a ton of apps it does not include HBO just yet so you may need to use another device to cast it to your TV. When interacting with the TV the lag time on button clicks on the remote and TV is almost none and the menus are very quick to react. 3. I am still getting used to the sound of the TV but I dont think its one of the best things about this TV. It can go very loud and it has some options for different modes like surround and dolby digital but I still think it would need a sound bar our alternate sound system if you want the true movie theater experience.

Great TV with awesome picture

Yensid25 10/9/2020

We love our LG CX OLED TV. It has a great crisp picture. The colors are vivid and the deep black levels allow you to see all of the details in the dark scenes too. Has a great picture no matter what we are watching sports shows movies and sports. Perfect settings out of the box that we hardly had to adjust. Compared to other TVs weve had in the past this was a huge plus that we really appreciated. Overall the picture quality really cant be beat. OLED technology is the best of the best and it shows on this TV. The design is amazing very slim goes well with any decor. We put ours in our family room and it fits in perfectly. Theres even a mode that allows it to become like a giant work of art complete with frame. So it can almost disappear into the room when needed. The design of most TVs have become very similar in recent years but this one will definitely stand out when you want it to while also being able to hide when needed. The built in apps allow easy access to any of our favorite streaming services. Disney+ Netflix Youtube TV all have access from the menu at the bottom. Which comes up with one simple push of a button. Another great feature is the quick access buttons you can program into your remote for your favorite and most used apps. We recommend this TV to anyone I received this product at a discounted price in exchange for my honest opinion.

Careful you can use a soundbar with this tv.

Joe Pro 10/3/2020

You cannot use an LG sound bar with this television unless you get a third party stand. there is another version that is meant to be mounted on the wall that one would probably be okay. The LG soundbars are obviously not meant to work with the 20/20 LG televisions as theyre too tall and the stand is too low. Otherwise its a great television if you have a dark room too much glare for a bright room.

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???
