Samsung 55" OLED 4K Smart TV vs Samsung S90H 55" OLED TV

Both are 55-inch Samsung OLED 4K sets with the same panel size, weight and dimensions, so the picture quality is close. The S90H (B) is the better pick for gamers and cable or antenna viewers: 120 Hz refresh, a built-in ATSC tuner, an optical audio output and Wi-Fi 6E. The AI TV (A) leans on processing and sound features, with the NQ4 AI Gen3 upscaler, OLED HDR+ and Dolby Atmos with top-channel speakers. Owners of both rate them 4.8 out of 5, and OLED's per-pixel contrast is the shared strength.

• Choose the Samsung OLED HDR AI TV if you want the stronger upscaling and built-in Dolby Atmos sound and do not need a tuner or 120 Hz.
• Choose the Samsung 55" OLED QE55S90HAEXXH if you game, watch over-the-air TV, or want the faster panel and newer wireless.
