Our Verdict

LG B3 OLED

LG C4 OLED

The LG C4 OLED is better than the LG B3 OLED. While they're very similar with nearly identical features, the C4 has the edge in almost every facet. It is visibly brighter in HDR and SDR, so all content pops noticeably more on the C4 than on the B3. Furthermore, the C4 is the better TV for those who own multiple HDMI 2.1 devices, as it has four full HDMI 2.1 ports with up to 4k @ 144Hz support, while the B3 is limited to two 4k @ 120Hz HDMI 2.1 ports. The B3's HDMI 2.1 ports are back-facing, meaning they're almost impossible to use when the TV is mounted flush against a wall. Finally, one of these ports is also the TV's eARC port, so you lose one of your high bandwidth ports if you have a soundbar connected to the TV.
