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

Both are 48-inch OLEDs with four HDMI 2.1 ports and 165Hz panels, so the split comes down to picture philosophy and software. The LG C6 adds Dolby Vision, which the Samsung S90H lacks, and its webOS is simple and fast. The Samsung counters with HDR10+ support, a brighter-feeling QD-style presentation, Tizen with seven years of OS updates, and built-in Google Gemini and Copilot. Buy the LG if you watch a lot of Dolby Vision movies and want the most balanced out-of-box picture; buy the Samsung if you want long software support and HDR10+ for gaming and streaming.

• Choose the LG C6 if you want Dolby Vision, a clean webOS interface, and the most filmmaker-friendly picture for movies and shows.
• Choose the Samsung S90H if you want HDR10+ support, seven generations of Tizen updates, and built-in Gemini and Copilot assistants.
