The LG B1 OLED is an excellent TV. It sits alongside the LG C1 OLED in LG's 2021 lineup, so it has many of the same features, with a different processor. It's pretty standard for an OLED as it delivers the same exceptional picture quality that they're known for. It can turn off individual pixels, resulting in a near-infinite contrast ratio and perfect black uniformity, making it a fantastic choice for use in dark rooms. Gamers should appreciate the variable refresh rate (VRR) support and HDMI 2.1 inputs, meaning that you can use the next-gen consoles to their full capabilities. Like most OLEDs, it doesn't get very bright, so it's not the best choice for well-lit rooms, but it still has incredible reflection handling. Unfortunately, OLEDs may be the victim of permanent burn-in, but we don't expect this to be an issue for people who watch varied content.
Note: LG USA labels it as 'Online Exclusive', so you can only get it directly from their website in the United States. It seems to be available at other retailers in Europe.
Our Verdict
The LG B1 OLED is an excellent TV overall. It performs best for watching movies in dark rooms because it has a near-infinite contrast ratio with perfect blacks. It's fantastic for gaming as it has VRR support, HDMI 2.1 inputs, and a near-instantaneous response time. It's also great for watching TV shows in a wide seating arrangement, but it doesn't get bright enough to combat glare. However, it risks permanent burn-in, which could be an issue if you constantly watch the same channel with static elements.

Differences Between Sizes And Variants
We tested the 55 inch LG B1 (OLED55B1PUB), which also comes in 65 inch and 77 inch models. For the most part, we expect our results to be valid for those models as well. It's only available through LG's website in the United States, but it seems to be available at retailers in Europe. Unfortunately, it's not available in Canada.

If you come across a different type of panel or your LG B1 doesn't correspond to our review, let us know and we'll update the review. Note that some tests like gray uniformity may vary between individual units.
Our unit was manufactured in June 2021, and you can see the label here.
Popular TV Comparisons
The LG B1 OLED is an excellent TV, which is what we've come to expect with OLEDs. It's essentially an updated version of the LG BX OLED with extremely similar performance. Even though it's a step down from the LG C1 OLED and doesn't get as bright, the differences between each are minimal. The one downside is that the B1 appears to be only sold online through LG in the United States, so it's harder to find than the C1, and it's not available in as many sizes. Still, if you can find the B1 for cheaper, it's worth getting.

The LG B1 OLED and the LG C1 OLED sit alongside each other in the 2021 LG lineup. They have many of the same features and performance, but they use different processors, which we don't test. The C1 gets brighter, but the difference isn't very noticeable. The C1 also has a wider refresh rate range because it has low frame rate compensation that allows the VRR to drop below 40Hz, which the B1 doesn't have. The B1 has much better gradient handling, so there's less banding in HDR content.
The LG B1 OLED and the Sony A80J OLED are both excellent TVs with a few differences. The LG is better for gaming because it has lower input lag. On the other hand, the Sony is slightly better for watching HDR content because it gets brighter and has better color accuracy, but this can vary between units. Overall, the differences between them are minor as most OLEDs deliver the same exceptional picture quality.
The LG B1 OLED and the LG CX OLED are two similar TVs. Picture quality is nearly the same on both because they each have a near-infinite contrast, but the CX gets a bit brighter. The CX's VRR can drop below 40Hz, which the B1 can't do because it lacks low frame rate compensation. Because the B1 is a 2021 model and the CX is 2020, the B1 has an updated version of the LG webOS that features a full home page with apps instead of a banner, and it comes with a redesigned remote, but it has the same functionality as the old remote anyways.
The LG B2 OLED is an upgrade from its predecessor, the LG B1 OLED. The main difference is that the B2 gets brighter, so its overall picture quality is superior; this makes it a better choice for well-lit rooms. However, if you're watching movies in dark rooms, there isn't much difference, except the B2 gets brighter in HDR, so highlights pop more.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
