Sync TV LED Backlight for 40-85 Inch Screens

Let the wall behind your TV glow with whatever is on screen, in real time.

This backlight matches the colors on your display and casts them onto the wall for a more immersive picture. It fits TVs from 40 to 85 inches and works with 4K HDMI 2.0 input devices such as TV boxes, game consoles, laptops, Blu-ray players, and PS4/PS5 (HDMI 2.1 sources are not supported). The system reads the video signal and adjusts the LED strip's color and brightness to follow the screen, and an AI-enabled chip finds the color sampling points automatically. Kits come sized for three ranges, 40-50 inch, 55-65 inch, and 75-85 inch, for a proper fit and even light. A one-button start handles daily use, with no Wi-Fi, apps, or accounts. The thermal design helps move heat away to support a longer LED life, and adjustable brightness softens the gap between a bright screen and a dark room to ease eye strain.

Good to know

Fits flat-screen TVs from 40 to 85 inches and needs an external HDMI 2.0 source; HDMI 2.1-only sources are not supported, and a smart TV cannot drive it from built-in apps alone. Install by cleaning the TV back, peeling the adhesive, fixing the four corners, and following the screen edges. Reset by holding the controller reset for 5 seconds until the strip flashes red, then unplug power for about 10 seconds and reconnect for a white-light test cycle.
