Is the LG C4 OLED better than the Samsung S90D?

Whether the Samsung S90D or the LG C4 is better depends on what you value most. The Samsung S90D generally offers superior raw picture performance with higher color brightness and wider color volume, provided you get a model with a QD-OLED panel. However, the LG C4 is the more versatile and reliable overall pick for most buyers because it supports Dolby Vision (the dominant premium HDR format) and uses consistent WOLED panels across all size configurations, eliminating any buying guesswork.
