Samsung S90D OLED 4K TV vs Samsung 65" 4K OLED Smart TV

Both are Samsung OLED 4K sets with 120Hz panels, so picture quality is close. The S90D is the better-documented, more feature-complete TV: it adds Google Assistant and Alexa, Bluetooth, Ethernet, USB, and Samsung's AI 4K upscaling, and reviewers consistently praise its contrast and motion. The Class 4K OLED is a larger 65-inch panel with four HDMI ports and Wi-Fi 6E, and its 4.6-out-of-5 owner rating is strong. Buy the S90D for a smaller room and the fuller smart and connectivity package; buy the Class OLED if screen size matters most and you want a bigger panel with more HDMI inputs.

• Choose the S90D if you want a 55-inch OLED with voice assistants, Bluetooth, Ethernet and Samsung's AI upscaling in a lighter, more connected package.
• Choose the Class 4K OLED if you want a bigger 65-inch OLED screen with four HDMI ports and Wi-Fi 6E for a large living room.
