Linkind HDMI 2.0 Sync Box with TV Backlight — 4K@60Hz, Alexa & Google Assistant

Turn your room into a cinematic light show

The Linkind HDMI 2.0 Sync Box pairs your favorite external devices with a vivid segmented LED backlight to create an immersive ambience that reacts in real time to movies, games, and music. This setup is designed for liveness and depth, with colors that flow and shift in harmony with the on-screen action. Important: to activate the sync feature, your video must come from an external HDMI device plugged into the box, such as a Fire TV Stick, Roku, Apple TV, PlayStation, or Xbox. The sync function does not work with the built-in apps on your Smart TV.

Enjoy crisp picture fidelity alongside vibrant lighting. The system supports 4K HDR at 60 Hz through HDMI 2.0 pass-through, meaning you can preserve sharp visuals while experiencing atmospheric lighting that mirrors the content. With 16 million colors and multi-zone dynamic lights, different sections of the strip can display distinct hues simultaneously, creating a halo effect that feels like part of the scene rather than a background glow.

For control, you can use voice commands with Alexa or Google Assistant, or manage settings from the companion app. This combination allows you to tweak modes, brightness, and colors without leaving your seat. A single flexible LED strip is designed to fit a wide range of screens, from compact 27-inch monitors to large 90-inch TVs, so you can tailor the glow to your exact setup. The system includes several dynamic modes that respond to music or scenes, helping you set the mood for everything from a focused gaming session to a relaxed movie night.

Expansion is straightforward: the box provides one HDMI input, and you can add an HDMI switcher to connect more devices. Remember: for the lighting to sync, always use external devices like a Fire Stick or game console rather than the TV’s built-in apps. This keeps the visuals aligned with your source material and reduces delay between on-screen action and ambient color shifts.
