“…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.

What people are saying

Rated 5 out of 5 by from An out of this world TV Upon first turning this TV on, completing the setup process, and thereafter turning on a film in Dolby Vision, I was mesmerized by the extraordinary picture quality that was presented to me. Having never owned an OLED TV in the past, I was unsure just how amazing an OLED TV will be, and let me just say that what I experienced, and what I was expecting was totally blown out of the water by the amazing stunning quality picture that this TV produces. I have the tv while not in use in Gallery mode, and the pictures that are displayed are so breathtaking, they appear as though the display is an actual canvas, very vibrant and life like. Among other things is the intuitive interface powered by WebOS, combined with LG's magic remote make it a winning combination. I really love that the remote features a moving cursor which makes navigating the interface a breeze. The LG gallery design is quite remarkable in that the TV is flush to the wall completely, without having any cables being in the way through LG's innovative design that hides all the cables in a uniform matter with recessed input panels.

Rated 5 out of 5 by from Do not buy from Value Electronics!! Do not buy from Value Electronics! They do not have tv’s in stock even when the website says that they do. It is a scam to get you to buy from them and their customer support is awful. The TV itself is beautiful and gorgeous and I couldn’t be happier after waiting for it be back in stock and ordering it directly from lg.

Rated 5 out of 5 by from Great TV for our Family! We received this TV and had it professionally installed in our family room. This is where it'd get used most by us and our 2 children (7 and 5). The GX right away was impressive in all lighting situations. Even during the day the picture is bright and vibrant where my old led would sometimes appear washed out when sun filled the room. The same goes for at night, the GX displays deep, beautiful blacks and grays where the prior led you could see some places where the back lighting distorted the black colors. We've been thoroughly impressed with the operating system as well, menus are easy to navigate, magic remote was quick to learn all of my connected devices, and the added benefit of being able to control my smart home devices is great! The GX doesn't include a stand but they do offer one. In place of a stand they included the best bracket I've seen for a TV yet. It's made perfectly for the TV and allows it to sit totally flush to the wall which adds to the beauty of the TV. Overall, our family is totally satisfied with this television and would definitely recommend to anyone in the market for one.

Would one LG TV's magic remote interact with another nearby LG TV that also uses a magic remote? I am in an open floor plan and would like to add this TV to the space, about 20-30 feet away.But the concern is that magic remotes will interact with wrong TV

Asked by: Boriss
LG Magic Remotes are Bluetooth devices and will have a range of about 33 feet (10m). They are only compatible with select LG Bluetooth enabled TVs that have the same year of development as the LG Magic Remote so a 2020 LG Magic Remote will only be compatible with a compatible 2020 LG TV. If the other TV that you have is a 2020 LG TV as the LG GX 65 inch Class with Gallery Design 4K Smart OLED TV w/AI ThinQ® (64.5'' Diag), Model # OLED65GXPUA is and it is within the Bluetooth range, both TVs will respond to commands from the LG Magic Remote at the same time...^IFV

Does LGOLEDCX77 have HDMI 2.1 I am looking to buy one

Asked by: Johndmach
So this confused me when I was researching it myself as well. To expand on The Rafcave's reply, HDMI 2.1 is LIMITED to 40Gbps on this TV and not the full 48Gbps of the HDMI 2.1 spec. However, there is no point in getting the full 48 Gbps bandwidth of HDMI 2.1 on this TV as the panel can only do 4:4:4 4k@120Hz with 10-bits HDR. Going to 48Gbps would not allow you to "do more" than the 40Gbps limit they have set.

Does the 77 come with a wall mount or VESA only? Need details if so. New home construction and need to prepare surface ASAP.

Asked by: ARAinTX
The LG GX 77 inch Class with Gallery Design 4K Smart OLED TV w/AI ThinQ® (76.7'' Diag), Model # OLED77GXPUA comes with a VESA compliant Wall Mount Bracket that is designed to take advantage of the TV's design allowing it to be mounted flush to the wall. The TV has a VESA Wall Mount Interface Pattern of 300 x 300 mm so you can also use third-party VESA compliant Wall Mounts that support that pattern if you prefer. Details for mounting the TV on the wall can be found in the owner's manual for the TV which can be downloaded from the support page for the TV on our site...^IFV
