Samsung S90D OLED 4K TV vs Sony Bravia A75L OLED TV

Both are 120Hz OLED 4K TVs with strong contrast and wide viewing angles, so the choice comes down to size and platform. The Samsung S90D uses QD-OLED for higher color brightness and runs Tizen with Google Assistant and Alexa built in. The Sony A75L is a larger 65-inch set with Google TV, Dolby Vision, and Sony's XR processor, which reviewers praise for motion and upscaling. Buy the Sony if you want the bigger screen and Dolby Vision; buy the Samsung if you want punchier color and Alexa on the TV.

• Choose the Samsung S90D if you want a brighter, more saturated QD-OLED picture and Alexa or Google Assistant on the set.
• Choose the Sony A75L if you want a 65-inch screen, Dolby Vision, and Sony's motion handling and upscaling.
