The TCL X11L is a flagship 4k TV released in 2026 as the successor to the TCL X11K. Whereas most brands have decided to focus on RGB Mini LED backlighting in their 2026 flagships, TCL went in a different direction with the X11L, which features a WHVA 2.0 panel with a regular Mini LED backlight featuring up to 20,736 dimming zones. The key feature is its improved quantum dot structure that TCL calls Super Quantum Dot, or SQD, which, combined with improved color filters, is advertised to produce much more vibrant colors than traditional quantum dot panels. It’s packed with every feature you’d expect to find in a flagship model, including an ATSC 3.0 NEXTGEN TV tuner, four HDMI 2.1-bandwidth ports, and an impressive array of smart features powered by Google TV 14. It has a built-in soundbar made by TCL and tuned by Bang & Olufsen. We bought and tested the 85-inch model, but it’s also available in a 75-inch and 98-inch size.

Note: Due to the high peak brightness of the TV, we had to use different measuring equipment for many of our tests, as the TV exceeds the peak luminance of our Colorimetry Research CR-100, which we normally use. As such, we combined our CR-100 with a Colorimetry Research CR-250 when necessary, as it’s designed for higher luminance measurements, but it’s not as sensitive as the CR-100 in low-light conditions.
