Our Verdict
LG G4 OLED
LG B4 OLED
The LG G4 OLED is better than the LG B4 OLED, mostly due to its brightness capabilities. The G4 overcomes more glare in a bright room thanks to its superior SDR brightness and reflection handling, and its higher HDR peak brightness means highlights pop out more in HDR movies, shows, and games. Colors are also brighter on the G4 thanks to its better color volume. The G4 has better overall image processing. It does a better job upscaling low-resolution content, cleans up more artifacts in low bitrate content, and has less banding in color gradients. Finally, the G4 is slightly better for PC gamers thanks to its 144Hz support.
