“…OLED is the best it gets. And LG’s 2020 OLEDs look better than ever…” Digital Trends, 5/7/20

"The most elegant wall-mountable designs we've ever seen." Tom's Guide, 1/6/20
iF Design Award 2020 Winner


Only OLED TVs use over 8.3 million pixels that emit their own light and turn completely off, creating a stunning picture that allows you to see virtually every detail.

  • Sharp Picture

    Unlike LCD or conventional LED technology, OLED uses millions of self-lit pixels to give you consistent detail, even when the cinematography gets dark.

  • Swift Response

    Individual self-lit pixels paired with the latest gaming features and tech give you an edge with less lag, high refresh rates, and incredibly smooth and responsive gameplay.

  • Smooth Motion

    OLED Motion is technology you see, but don't notice. It's motion handling for fast movements in sports and action sequences. Kickoff returns look just as smooth at home as from 50-yard line seats, with less stuttering to slow down the big car chase.

  • Slim Design

    LG OLED technology unlocks a new world of TV design with a minimalist bezel and impossibly thin profile, putting the spotlight on your content while complementing your home's interior.

Installing Your OLED GX is Easier
Than You Think

Gallery Mount with Recess Box*

The GX was made for this: no gap, no shadow, nothing in your way.
*Professional installation recommended.

Flush Mount with Raceway Cable Concealer**

Get the flush mounted look with the supplied wall mount and a few touches to hide the wires.
**Raceway cable concealer sold separately.

Standard VESA Mount***

If you already have a VESA wall mount in place, chances are, it'll fit your new GX.
***300x300 mounting pattern, be sure to check your mount is rated for the size and weight of your OLED GX.

Display Stand

Use the optional feet (sold separately) to put your GX on display.

See how perfect LG OLED TVs can be

Bring home the world’s #1 selling OLED TV. Only OLED pixels emit their own light, allowing for perfect black, intense color and stunning picture. Other TVs pale in comparison. There's LG OLED, then there's everything else.
*The cable may be visible depending on installation environment.
**Depending on installation environment, there may be a slight gap between the TV and the wall.
***Installation into a stud is recommended. Please note that the anchors supplied may not be appropriate for all situations. Read all instructions and consult with a professional, if necessary, prior to starting installation.
****A TV stand is NOT included with the LG OLED GX. As this model is designed to be wall-mounted, it includes a slim wall mount bracket. The TV stand can be purchased separately.

Only cutting-edge OLED pixels emit their own light

Movies mesmerize. Sports feels like you're at the stadium. Millions of OLED pixels emit their own light independently, and can be completely turned off. This unveils perfect black, over a billion rich colors, and infinite contrast. Other TVs pale in comparison.
*Calculation based on multiplying 8K resolution (7680 x 4320) and four sub-pixels.
α9 Gen3 AI Processor 4K

See more of your content in 4K

Our most advanced 4K processor uses AI and deep learning to authentically upscale lower resolution content, translating the source to 4K's 8.3+ million pixels. The technology is so good, you might mistake non-4K for true 4K*.

Rated 5 out of 5 by from Perfect for gaming I think my wife likes it more than me.. that speaks volumes when if comes to electronics.

Rated 5 out of 5 by from Just a beautiful set I bought this TV as a retirement gift to myself and I've enjoyed every second of it. The picture is just gorgeous whether I'm streaming Netflix or Amazon prime. When that 4k kicks in it's just breathtaking. I've been using the preset picture settings so far haven't gotten it professionally calibrated yet. It looks so good I'm in no rush to get it done but I'm sure I will I some point in the future. To my amateur eyes I can't see how it gets better than this.

Will this unit run 24/7 - 365?

Asked by: CC Fit1
As with any other TV, regardless of the technology, it employs, although it is not recommended, you could run the LG GX 55 inch Class with Gallery Design 4K Smart OLED TV w/AI ThinQ® (54.6'' Diag), Model # OLED55GXPUA 24/7 but with the understanding that doing so in the long run, for any TV left on all the time, it will get dimmer, sooner than if you watched for 4-6 hours a day. There is no specified limit for how long you can run any TV, but the more you leave it on for extended periods of time, the sooner it will fail. This is not only true for TVs, but for most, if not all electronic products...^IFV

I have a LG OLED55GXPUA. I have installed the Amazon Music app, which works but it needs to be re-registered every day. I've tried removing and reinstalling the Amazon Music App, have tried updating the TV software, and did a factory reset of the TV.

im trying to figure out why the espn+ app is not available, do you know when it will be available

Asked by: anthonys4736
Regrettably, ESPN+ is not currently available on the LG GX 65 inch Class with Gallery Design 4K Smart OLED TV w/AI ThinQ® (64.5'' Diag), Model # OLED65GXPUA or on our webOS platform. However, we are continually working to add the latest streaming applications, such as ESPN+, but cannot provide a concrete timeline right now. Hulu is a preinstalled app on the TV and you can log into your Hulu account and look for the Activations section where you can select Activate next to Disney+ and ESPN+ to create your new Disney+ and ESPN+ accounts to start streaming. You can also get ESPN+ with the Disney Bundle (Disney+ is also a preinstalled app on the TV)...^IFV

Is this tv OLED77GXPUA shipped with a base(stand)?  If not, what is the proper model number that includes a base (stand)?

Asked by: lg104
The LG GX 77 inch Class with Gallery Design 4K Smart OLED TV w/AI ThinQ® (76.7'' Diag), Model # OLED77GXPUA is designed for wall mounting so it ships with a special Gallery Wall Mount that is designed to take advantage of the TV's design so it can be mounted flush to the wall. The base (stand), the LG GX OLED 77 inch TV Stand Mount, Model # AN-GXDV77 is not included with the TV and it has to be purchased separately. You can visit our product detail page for the stand at https://www.lg.com/us/tv-audio-video-accessories/lg-gx-oled-tv-stand-mount-an-gxdv77 and click on the 'Where to Buy' button to find retailers in your area or online sites where it can be ordered from.

Have an earlier version of this OLED and burn in is horrible from day one. Not because of pausing the image but because so many networks run banners/logos at the same location on their screens. Is this model capable of handling this? What is your warranty

Asked by: wajeko
In the OLED Screen Saver settings for the LG GX 55 inch Class with Gallery Design 4K Smart OLED TV w/AI ThinQ® (54.6'' Diag), Model # OLED55GXPUA is a Pixel Refresher feature that calibrates any issues that may arise on the screen when your TV has been turned on for a long time. When you select 'Operate once when TV is off', when the TV is turned off, the Pixel Refresher will start running. If you select 'Start Now' while the TV is on, the TV will turn off immediately and the Pixel Refresher starts running. The TV will automatically turn back on when calibration is done. Calibration takes more than an hour. The Screen Shift feature moves the screen slightly at regular intervals to prevent images from sticking on the screen. Then there is Logo Luminance Adjustment that adjusts the luminance of static images such as logos or banners to correct potential picture quality issues. Which earlier version OLED TV do you have? I have a 2015 LG OLED and I watch a lot of channels like Bloomberg, MSNBC, CNN, Fox, etc., that run a lot of banners and logos and I have had my kids play their video games on the TV and do not have a trace of burn-in or image retention on the TV to date...^IFV

What are the difference between the OLED Gallery, Wallpaper TV's, vs. the other OLED models?  Is there a comparison chart among OLED models?

Asked by: Dave 35806
We do not have a comparison chart for our OLED TVs, but we do have an 'Add to Compare' function on the product pages for each OLED TV in our current lineup that you can use to compare the LG OLEDs with. The Gallery (GX) screen not as slim as the Wallpaper (WX) screen, which has a separate electronics/speaker box that has been redesigned for the 2020 version. On the other hand, all ports, speakers, and electronics are built-in. GX comes bundled with a slim wall bracket solution. An optional soundbar (SNX7) for GX will also be available. The main difference between all the LG OLED series is the design and the assignment of HDMI 2.1 ports. While LG covered most of the HDMI 2.1 related specs in its 2019 TVs, including full 48Gbps bandwidth support in all of the HDMI ports for its 4K and 8K TVs, the market situation indicates that content requiring 48Gbps is not available in the market. Based on this, LG decided to re-allocate the hardware resources of 2020 chipsets optimizing for AI functions including the CPU&GPU As a result, the HDMI ports of 2020 4K TVs have a bandwidth of 40Gbps which supports up to 4K 120P 4:4:4/RGB 10bit. 8K TVs (ZX OLED and NANO99 NanoCell LCD) include 2 HDMI ports that support 48Gbps and 2 that support 40Gbps. Despite the change, 2020 LG TVs still provide the best technologies available today to maximize the consumer viewing experience. All the HDMI ports on the GX and CX series are HDMI 2.1 ports while the BX series features 2 x HDMI 2.1 ports and 2 x HDMI 2.0 ports...^IFV

This TV has recommended as installed into studs for mounting, which totally makes sense.  I am curious if the mounting hardware allows for the TV to be shifted to the right or left of the stud mounting as it will be off center if so?

Asked by: PabloF
Hi PabloF. As you noted, it is recommended that the LG GX 65 inch Class with Gallery Design 4K Smart OLED TV w/AI ThinQ® (64.5'' Diag), Model # OLED65GXPUA be installed into a stud because that ensures that the TV is mounted securely so there is no chance of it falling. Regrettably, we cannot advise you on installing it in any other manner other than what is recommedned and if you want to install it any other way, we highly recommend that you consult with a professional installer. The professional installer will assume responsibility for the installation...^IFV
