LG C6 Series OLED TV vs Samsung 42” S90H OLED 4K Smart TV

Both are 4K OLEDs with 165Hz gaming support, but they target different rooms. The LG C6 is the better all-round home theater set: 55 inches, Dolby Vision, Dolby Atmos, a 2.2-channel 40W speaker system and four full HDMI 2.1 ports. The Samsung S90H wins on glare handling and motion clarity at 42 inches, and owners rate it very highly. Pick the LG for a dark living room with a soundbar or none; pick the Samsung for a bright room or a desk where reflections are the problem.

• Choose the LG C6 if you want a larger 55-inch picture with Dolby Vision and Dolby Atmos and plan to wall-mount or pair it with a soundbar.
• Choose the Samsung S90H if your room is bright, your space is small, or you want a 42-inch OLED that stays readable in daylight.
