Our Verdict
LG B1 OLED
LG C1 OLED
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.
