Enjoy realistic images and deep sound with the TCL QD Mini-LED C61K 4K (2025). C61K TVs have a QD Mini-LED display. Behind the screen, there are thousands of small LED light that light up or dim the pixels. That way, the brightness is high and you can enjoy a powerful contrast. You won't miss a detail of movie or series and see almost no gray glow around bright objects. Between the pixels and the backlight, there's a layer of Quantum Dots. These particles filter light and ensure a vibrant, bright color representation. Keep your viewing distance in mind before choosing an inch size. The farther you're away from the screen, the larger the TV we recommend.
