Samsung M80HD Mini LED 4K TV vs TCL M8LF Series 4K Mini LED Fire TV

Both are Mini LED 4K sets, but they are built for different rooms and different buyers. The Samsung M80HD is a 55-inch 120Hz set with Samsung's Tizen platform and Vision AI processing; the TCL M8LF is a larger 75-inch Mini LED with full array local dimming, Dolby Vision and HDR10+, a native 144Hz panel and Fire TV with hands-free Alexa. Owners rate the TCL higher on picture and gaming, while the Samsung is the safer pick for a smaller room and for people who prefer Samsung's interface and upscaling. If size and HDR format support matter most, the TCL wins; if you want a mainstream 55-inch with strong motion for sports and a familiar smart system, the Samsung is the simpler buy.

• Choose the Samsung M80HD if you want a 55-inch 120Hz Mini LED set with Samsung's Tizen apps and Vision AI processing in a smaller room.
• Choose the TCL M8LF if you want the biggest screen, full array local dimming, Dolby Vision and a 144Hz panel for movies and gaming.
