Overview

The TCL 75QM851G brings the QM8 combination of fast response and larger speakers to a 74.5-inch screen. The VA panel gives 4K at 59 ppi with a 48–144 Hz range, variable refresh and a 10-bit (8-bit + FRC) signal, supporting HDR10, HDR10+, Dolby Vision and Dolby Vision IQ. Speakers are listed as 2 × 20 W plus 2 × 10 W. It weighs 38.5 kg, so wall mounting needs helpers and a strong bracket, and it suits a large lounge.
