Our Verdict

LG C3 OLED

Samsung S90C OLED

The LG C3 OLED and the Samsung S90C OLED are similar TVs occupying the same market position. Of the two, the Samsung is the better gaming TV and slightly better overall TV, while the LG is the better TV for movie fans. The Samsung has a wider color gamut and gets brighter than the LG, especially in HDR; not only that, but it also maintains its HDR brightness better in Game Mode. It also supports 4k @ 144Hz (120Hz on the 83-inch model), while the LG is limited to 4k @ 120Hz. However, the LG supports DTS audio formats and Dolby Vision, making it great for Blu-ray fans. It also has better low-quality content smoothing than the Samsung TV, making it better for watching streaming content, especially in low-bitrate situations.
