Overview

Brightness is the standout feature of the TCL 55QM751G, a 2024 model that lists 600 nits. The 54.6-inch VA panel gives 4K at 80 ppi with a 48–144 Hz range, variable refresh, 97% DCI-P3, a 5.7 ms response and a 10-bit (8-bit + FRC) signal, supporting HDR10, HDR10+, Dolby Vision and Dolby Vision IQ. Two 15 W speakers are built in and the TV weighs 14.8 kg. It is a good fit for bright living rooms. It also suits rooms with big windows where a dim TV would struggle against daylight.
