Our Verdict
The LG B7 is a great TV for a mixed usage. Its picture quality is remarkable, and it features a large set of powerful features that make it a well-rounded set fit for almost any usage.
- Perfectly uniform blacks thanks to infinite contrast
- Great picture even from an angle
- Low input lag for gaming
- Static images can get "stuck" temporarily
- Screen brightness varies with content being displayed (ABL)
Exceptional 4k TV for watching movies in a dark room. The LG B7's ability to shut off individual pixels gives it perfectly uniform blacks and an infinite contrast ratio. Combined with its 4k resolution, this makes for an exceptional home theater.
Great TV for watching TV shows in a brighter environment. The B7's screen finish takes good care of reflections, and it gets just bright enough not to appear dim in most environments.
Great TV for watching sports. The B7's OLED screen displays very uniform colors so grassy football fields don't have any banding or blotches. It also handles motion very well, making fast moving players look very fluid.
The B7A is a great 4k gaming TV. It's very responsive thanks to its low input lag and low amount of motion blur. Its overall great picture quality also helps make video games particularly immersive.
The LG B7's HDR capabilities are excellent. The very high dynamic range produced by its infinite contrast ratio and its very wide color gamut creates a realistic and vibrant image. It's not the brightest TV, but its capable of brightening small highlights well enough to give a very nice effect.
Great TV for HDR gaming. The B7's excellent picture quality and HDR capabilities are well retained for gaming, and its input lag is not affected by the type of input. People that find the image too dim might prefer to enable the "Adaptive Contrast" feature which helps brighten up the picture for gaming.
The LG B7 is a good TV to use as PC monitor. Its input lag is low, and it supports even essentials like chroma 4:4:4 as well as more niche features like a 120 Hz input. Unfortunately, some users might not find it bright enough, and some static content can have ghosts remain temporarily if kept on-screen too long.

Differences Between Sizes And Variants
We tested the 55" (OLED55B7A). For the most part, we expect our review to be valid for the 65" (OLED65B7A).
The B7P (OLED55B7P, OLED65B7P) is a warehouse exclusive model in the USA and is also available in Canada but we expect its performance to be identical. One difference is that the B7P can play Dolby Atmos using its own speakers because it has a 2.2 speaker setup, while the B7A can't play Atmos with its own speakers because it only has a 2.0 setup. The B7A can still passthrough Atmos to an external receiver though.
The B7V (OLED55B7V, OLED65B7V) is a European variant which sports a different stand, similar to what is found on the LG SJ8500. We also expect this to offer the same performance as the German B7T (OLED55B7T, OLED65B7T).
If someone comes across a different type of panel or if their LG OLED 55B7A (55OLEDB7) or 65B7A (65OLEDB7) doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.
| Size | US Model | Warehouse Model | EU Model |
| 55" | OLED55B7A | OLED55B7P | OLED55B7V |
| 65" | OLED65B7A | OLED65B7P | OLED65B7V |
Popular TV Comparisons
The LG B7 is a great TV overall and offers a lot of value for money. Since it has the best picture quality while still being reasonably priced, it's a very competitive model. See our recommendations for the best smart TVs and the best 4k TVs.
The LG C8 OLED is somewhat better than the LG B7/B7A OLED. While the overall performance of the two is very similar, the LG C8 has an optional Black Frame Insertion feature that the B7A doesn't have. This feature helps to improve the perceived clarity of motion on the C8, at the expense of some brightness.
The LG B8 OLED is somewhat better than the LG B7/B7A OLED. The LG B8 has slightly better motion handling due to the black frame insertion (BFI) feature, which is great if you play video games. Also, the LG B8 performs somewhat better in temporary image retention if you use it as a PC monitor, although this could be due to panel variance. On the other hand, the LG B7A has marginally better input lag in HDR gaming and marginally better viewing angles, although both TVs are very good in that respect.
The performance of the LG B7/B7A OLED and LG C7 OLED is nearly identical. There are no major differences other than the design. The LG C7 and the B7P variant have a 2.2 speaker setup, which can internally decode Dolby Atmos sound. The B7A variant only has a 2.0 speaker setup and can't decode Dolby Atmos internally, although the C7 and all B7 models can output Atmos to an external receiver.
The LG B7/B7A OLED is better than the Sony X900F, unless the possibility of burn-in concerns you. The LG B7A uses an OLED panel, which offers perfect dark room performance and wide viewing angles. The B7A is prone to temporary image retention, and there is the possibility of permanent burn-in. The Sony X900F appears to be immune to burn-in and does not experience any image retention.
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.
