Our Verdict
LG CX OLED
LG C4 OLED
The LG C4 OLED is a good upgrade from the LG CX OLED if you're looking for a brighter OLED. The C4 is brighter in SDR and, combined with its slightly better reflection handling, fights more glare in a room with the lights on. Highlights in HDR content also pop more on the C4 due to its higher HDR peak brightness. Additionally, the C4 supports a 144Hz refresh rate, which is great if you're a PC gamer.
