Samsung S85H OLED 4K Smart TV vs Roku Pro Series 4K OLED TV

Both are 120Hz OLED 4K sets with strong contrast, but they suit different buyers. The Samsung S85H is the better all-round TV for movies and gaming: four HDMI ports, G-SYNC and FreeSync Premium, Dolby Atmos with object tracking, and a Tizen platform with up to seven years of OS updates. The Roku Pro Series wins on HDR format support, adding Dolby Vision and HDR10+ that the Samsung lacks, and its Roku interface is simpler for casual viewers. Note the listing mismatch on the Roku: the name says 65-inch but the specs describe a 55-inch class panel, so confirm the size before ordering. Owners of the Samsung praise picture, upscaling and setup; the recurring complaint is shipping damage in the thin retail box.

• Choose the Samsung S85H if you want the most gaming features and HDMI inputs, a brighter smart platform with long update support, and you are buying a smaller 48-inch set.
• Choose the Roku Pro Series if Dolby Vision and HDR10+ matter to you and you prefer Roku's plain, fast interface over Tizen.
