TCL QM7L 55" Mini LED 4K TV vs TCL QM6K 75" QD-Mini LED TV

The QM7L is the better picture for a bright room and the better gaming set: SQD-Mini LED with up to 2,100+ dimming zones, up to 3,000 nits and 144Hz with two HDMI 2.1 ports. The QM6K wins on size and immersion: 75 inches of QD-Mini LED with Dolby Vision, HDR10+, Onkyo audio and a matte screen owners say keeps glare down. Owners of the QM6K praise colors, blacks and build but report occasional streaming glitches and menu lag and say it takes two people to lift. Buy the QM7L for a smaller room, HDR punch and console gaming; buy the QM6K for a big main screen at a farther seat.

• Choose the TCL QM7L if you sit closer, watch in a bright room, and want the brightest HDR, the most dimming zones and two HDMI 2.1 ports for a console.
• Choose the TCL QM6K if you want the biggest screen for movies and sports, with Dolby Vision, HDR10+ and Onkyo sound built in.
