The LG B9 OLED is a remarkable TV with excellent picture quality that displays perfect blacks. It has excellent wide viewing angles, good SDR peak brightness, and handles reflections well. This TV has a wide color gamut and decent HDR brightness, but the aggressive ABL can become bothersome. Motion looks crisp thanks to the nearly instantaneous response time, and the TV has a motion interpolation feature that can help minimize stutter in movies. Gamers will enjoy a responsive gaming experience thanks to the very low input lag, but unfortunately, just like all OLED TVs, it has the possibility of developing permanent burn-in.

PC Monitor
The LG OLED B9 is a great TV for use as a PC monitor. It displays proper chroma 4:4:4 in most resolutions so text looks clear. It has a very low input lag and an extremely fast response time that delivers fast-moving content with almost no blur. Unfortunately, just like all OLED TVs it runs the risk of permanent burn-in and this can be an issue if you use it as a PC monitor for extended periods of time.
We tested the 55" B9 (OLED55B9PUA), and we expect our results to be valid for the 65" (OLED65B9PUA) and the 77" (OLED77B9PUA) models as well.
If someone comes across a different type of panel or if their LG B9 OLED 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.

The B9 is an excellent OLED TV and outperforms most TVs except the C9 and the E9. See our recommendations for the best OLED TVs, the best 4k TVs, and the best smart TVs.
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 C2 OLED is better than the older LG B9 OLED. There's not much difference in picture quality: they both display deep, uniform blacks in a dark room with no blooming around bright objects. The C2 is much brighter in HDR, so bright highlights stand out much better. The C2 also has more advanced gaming features, including variable refresh rate support to reduce screen-tearing.
The LG CX OLED is a bit better than the LG B9 OLED. The CX can get brighter in HDR, it has much better out-of-the-box color accuracy, and its BFI features works at 120Hz. The B9 has slightly wider viewing angles and the gray uniformity is better, but this could be due to panel variances.
The LG B9 OLED and the LG B8 OLED have very similar picture quality overall. The B9 is more future-proof, as it supports some great new features, including HDMI 2.1, eARC, and HDMI Forum's variable refresh rate technology, which is currently only supported by the Xbox One.

How We Test TVs
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.
