Samsung 85" M80H Mini LED 4K TV vs Roku Pro Series 55" 4K QLED TV

These are different classes of TV, not close rivals. The Samsung M80H is an 85-inch Mini LED set with a 144Hz panel, HDR10+ and HLG, and Tizen's full app library; the Roku Pro Series is a 55-inch QLED Mini LED with a 120Hz panel and the Roku OS. Buy the Samsung for a large, bright living room where movies and console gaming share the screen. Buy the Roku for a smaller room where the interface and simple remote matter more than size. Owners rate the Samsung well at 4.7 from 562 ratings; Roku's Pro Series is praised for picture per inch and its OS, but it cannot match the Samsung's scale.

• Choose the Samsung M80H if you have the wall space for 85 inches and want a bright Mini LED panel with 144Hz gaming and the deepest app and game selection.
• Choose the Roku Pro Series if your room suits 55 inches and you want Roku's simple interface and remote more than sheer screen size.
