Our Verdict
LG C4 OLED
LG G4 OLED
The LG G4 OLED is better than the LG C4 OLED. The G4 gets brighter overall, so it overcomes more glare in a bright room while watching SDR content, and highlights pop more in HDR content. The G4 also maintains its HDR brightness much better while in 'Game Optimizer.' On top of that, the G4 is more accurate before calibration and has less banding in colors.
