Samsung 65" M80H Mini LED 4K TV vs Samsung M80H Series 55" 4K TV

Both are Samsung M80H Mini LED sets with the same NQ4 AI Gen2 processor, Tizen, HDR10+ and VRR, so picture character is close. The 65-inch M80H is the one to buy for a main room: bigger screen, 144 Hz panel, 3 HDMI ports and a 2026 model year. The 55-inch M80H suits smaller rooms and has a much larger owner base, but its listing is muddled on size and refresh rate, so confirm the panel before you commit.

• Choose the Samsung 65" M80H if you want the bigger screen, a 144 Hz panel for gaming and the newest model year in a main living room.
• Choose the Samsung 55" M80H if your room fits a 55-inch set and you want the same Mini LED picture and Tizen platform in a smaller size.
