The LG BX OLED is the entry-level TV in LG's 2020 OLED lineup, and like most OLED TVs, it offers excellent overall performance. It has an infinite contrast ratio and perfect black uniformity, ideal for watching movies in dark rooms. Gamers should appreciate its FreeSync variable refresh rate (VRR) support and G-SYNC compatibility. It has a near-instant response time that results in clear motion, but that means lower-frame rate content appears to stutter. This TV has wide viewing angles, so it's a great choice for a wide seating arrangement. Even though it doesn't get bright enough to combat glare, it has outstanding reflection handling, so it performs well in most fairly-bright rooms. Sadly, like any OLED TV, it has the risk of permanent burn-in, but this should only be an issue with constant static elements, like if you use the TV as a PC monitor or if you only watch the news.
Our Verdict
The LG BX OLED is an excellent overall TV. With its OLED technology, it can individually turn off pixels, resulting in an infinite contrast ratio and perfect black uniformity, so blacks appear black when viewed in the dark. It's outstanding for gaming because it has a near-instant response time, VRR support, and really low input lag. Sadly, it doesn't get very bright, so it's not ideal to use in extremely bright rooms. Lastly, it has wide viewing angles if you want to watch TV or sports with friends and family.

Popular TV Comparisons
The LG BX is an excellent TV, and like most OLED TVs, it delivers amazing overall picture quality with deep, inky blacks. It has much better out-of-the-box color accuracy than its predecessor, the LG B9 OLED, which is a nice touch if you don't want to get your TV calibrated. Sadly, the LG BX doesn't get as bright as the LG CX OLED, which could be disappointing if you want to place it in a bright room. Also, see our recommendations for the best OLED TVs, the best 55 inch TVs, and the best 4k TVs.
The LG CX OLED is slightly better than the LG BX OLED. The CX gets brighter, handles gradients better, and comes with a sturdier, metal stand. However, the BX has slightly wider viewing angles, but this may vary between units.
The LG BX OLED and the LG B9 OLED are very similar TVs. The B9 gets brighter, and it has better gradient handling, while the BX has much better out-of-the-box color accuracy, and its Black Frame Insertion feature flickers at 120Hz. Other than that, the two TVs are built the same way and have the same stand.
The LG C1 OLED and the LG BX OLED perform similarly overall since they both use OLED panels with near-infinite contrast ratios, nearly instant response times, and wide viewing angles. However, the C1 is available in more sizes and gets a bit brighter in HDR. It also has four HDMI 2.1 ports, while the BX only has two.
The LG BX OLED is much better overall than the Sony X900H, but they have different panel types. The LG has an OLED panel with self-emitting pixels, so it has an infinite contrast ratio and perfect black uniformity. It also has wider viewing angles and a near-instant response time for gaming. On the other hand, the LED panel on the Sony gets much brighter, and it doesn't have the risk of permanent burn-in like the LG.
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.
