“…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

Just because it wasn't filmed in 4K doesn't mean you can't see it that way. 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*.
*Image quality of upscaled content will vary based on the source resolution.
ThinQ AI

Do any of your OLED TV's have center channel inputs so I can use the TV's speakers as a center channel? If so, which models?

Asked by: BigTipper
None of our 2020/2021 LG OLEDs have Center Channel inputs. They all either have HDMI eARC ports or Optical Digital Audio Outputs for audio. Audio can be played through the TV’s Internal Speakers and External Audio Devices simultaneously. You can use the TV's built-in speaker and Bluetooth speakers for simultaneous sound output that provides you with realistic surround effects when watching a movie or drama, and you can connect up to two Bluetooth devices of the same model to set the left/right surround sound. Audio is played through the TV’s built-in speakers and the audio device connected to the digital optical audio output port simultaneously. You can wirelessly connect the TV to WiSA Speakers to enjoy high-quality sound and select DEVICE LIST to adjust detailed settings for WiSA Speakers...^IFV

Hi, would this work well with Bose 525 series ii surround system? Is it advisable to use Bose with this OLED? I was told at Best Buys that it is not advisable to use this as it may impact the quality of the video. I appreciate your guidance. Thanks

Asked by: OLED_FANS
Regrettably, we are not familiar with the specifications nor connectivity for your Bose Series II Surround System and cannot advise you how well it would work with the LG GX 77 inch Class with Gallery Design 4K Smart OLED TV w/AI ThinQ® (76.7'' Diag), Model # OLED77GXPUA. The OLED77GXPUA is a Bluetooth-enabled TV (Bluetooth ver. 5.0) so it can be paired with any Bluetooth-enabled Surround Sound System for a wireless Bluetooth connection. It features an HDMI eARC (HDMI 2) port that can be connected to any Surround System that has an HDMI eARC port and it also features an Optical Digital Audio Output that can be connected to any Surround Sound System that has an Optical Digital Audio Input. There is no reason why using the Bose Series II Surround System with the OLED77GXPUA should impact the video quality unless the Bose Series II Surround System is not shielded, but it should be shielded like every other Surround Sound System. We highly recommended that you contact Bose to inquire if they are aware of any issues with the system with any TV and get their advice...^IFV

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
