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.

See how OLED redefines picture quality

Once you’ve seen LG OLED TV with your own eyes, you'll understand. It’s stunning picture that redefines quality. 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. From the gridiron to the iron throne, no detail goes unseen.
*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 The Future Starts Here Wow, this makes the initial jump years ago from SD to HD pale in comparison. Sleek, modern design sets the stage for the best picture and audio I have seen and heard yet from a TV. Incorporating the latest developments in AI and internet streaming service, while also leading the way in the next generation of gaming and video, best all around picture I could ask for!

Rated 3 out of 5 by from Got 48" but issues right away Bought this tv June 7th. Took about a week to get. Waited 4 days to setup cause I was working alot. Noticed a grey line right away. Have gotten the run around ever since. Cant seem to get a tech to check it out and they won't give me any replacement information or return information. Have called 6 times and nothing has been done. First LG experience and if they don't fix it, will be my last. Great picture quality besides that and sound is pretty good also.

Is there a way to permanently turn off the motion control on the remote?

Asked by: Des85

Is the following model number the United States version of the 2020 LG 48" 4K TV? "OLED48CXPUB" or should it be "OLED48CXPUA” instead. Typically I see "PUA" as a United States version.

Asked by: BattlefieldVeteran

Interesting that this TV is being marketed towards gamers when OLEDs still have horrible image retention issues. PUBG has destroyed my 65" C7 so how will this panel differ?
