LG C5 OLED TV vs Samsung 42” S90H OLED 4K Smart TV

Both are OLED 4K sets with four HDMI 2.1 ports and strong gaming features, so the choice comes down to size and priorities. The LG C5 is the better all-round pick for a living room: it comes in large sizes, has Dolby Vision and Dolby Atmos, and reviewers rate it among the best TVs of 2025. The Samsung S90H is the one to get if you want a small 42-inch OLED or a matte, glare-free screen for a bright room. Owners of both praise picture quality; C5 owners report more software bugs and ads, while S90H owners say it takes work to dial in the picture.

• Choose the LG C5 if you want a big-screen OLED with Dolby Vision, Dolby Atmos and wide size options for movies and console gaming.
• Choose the Samsung S90H if you need a 42-inch OLED or a glare-free screen that holds up in a bright room.
