The TCL QM8L television has established a new standard for display brightness. In recent tests, it achieved a peak brightness of 3,956 nits when displaying a 10% white field with an HDR10 signal in Movie mode. This performance exceeds that of many previously tested models, including the X11L and older QM9K, solidifying its position as the brightest TV available in typical consumer sizes.
The QM8L also exhibits strong color capabilities. It covers 86.96% of the expansive BT.2020 color space, a figure comparable to high-end offerings from brands like Samsung and Sony. While minor quibbles exist, such as slight yellow tints in whites and redder magentas, its overall color accuracy and wide gamut are impressive, especially in Dolby Vision modes.
This remarkable brightness and wide color gamut performance, particularly among RGB LED TVs, position the QM8L as a standout choice for consumers prioritizing visual fidelity. It is recognized with a PCMag Lab Award for its exceptional brightness in the sub-100-inch TV category.
