LG C6 65" OLED evo TV vs Samsung QE65S90HAEXXH 65" OLED 4K Vision AI Smart TV Tizen S90H (2026)

Both are 65-inch 4K OLEDs with 165Hz VRR and four HDMI 2.1 ports, so the picture and gaming gap is narrow. The LG C6 has the edge for movies and console gaming: Dolby Vision, G-Sync and FreeSync Premium, a 0.1ms response time, and 40W 2.2-channel Dolby Atmos sound. The Samsung S90H counters with a glare-free anti-reflection panel, Samsung's Vision AI assistant, and a much larger owner base behind its 4.9 rating. Buy the LG if Dolby Vision and calibrated film modes matter most; buy the Samsung if your room is bright and you want the glare-free coating.

• Choose the LG C6 if you watch Dolby Vision movies in a dim room, game on a PC or console with G-Sync or FreeSync, and want strong built-in Atmos sound.
• Choose the Samsung S90H if your room has windows or lamps that reflect on the screen, or you want Bixby, Alexa and Google Assistant built into the TV.
