Our Verdict
LG A1 OLED
LG B2 OLED
The LG B2 OLED has more features than the LG A1 OLED, so if you're a gamer and need HDMI 2.1 bandwidth and VRR support, the B2 is the better choice. The B2 also performs better in well-lit rooms as it gets brighter, and highlights pop more in HDR. If you don't care about extra features and you're not after premium picture quality, the A1 delivers the same incredible dark room performance as the B2, thanks to its near-infinite contrast ratio.
