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.

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.

Gallery Design

A TV that's a work of art

This is art-inspired TV. Perfect lines. Unbelievably thin bezel. Impossibly slim. No gap from screen to wall. LG OLED TVs are designed, crafted, and engineered to put the spotlight on your content, yet complement your home's interior even when they're turned off.


*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.
