TCL 50" QM6K QD-Mini LED 4K Google TV vs TCL QM6K Series QD-Mini LED 4K TV

Both are TCL QM6K QD-Mini LED sets with the same processing and gaming features. The real choice is size: the 50-inch suits a bedroom, small living room or desk setup, while the 75-inch is built for a main room where you sit several feet back. The 50-inch is the better-documented set here, with a 144Hz native panel, four HDMI ports and a 4.2 rating from over 1,200 owners. Pick the 75-inch only if the bigger picture matters more than port count and confirmed refresh specs.

• Choose the TCL 50" QM6K if you sit close, want a 144Hz panel with four HDMI inputs, and need a set that fits a smaller wall or stand.
• Choose the TCL 75" QM6K if you have a large room, sit far back, and want the same Mini LED picture at a much bigger size.
