HDMI Sync RGB Light Strip 2M for TV and Computer Display Backlighting DC12V

This HDMI sync RGB light strip kit brings ambient lighting to your home cinema or gaming setup by matching on-screen colours in real time. The system uses a compact junction box that reads the video signal and controls the 2-metre LED strip accordingly. Installation is straightforward: connect the box between your source and display, power both units separately, and mount the strip along the back of the screen. The controller measures 160×90×20mm and runs on DC12V, while the junction box requires a separate 5V 1A supply. Suitable for indoor use only, with an IP20 rating.

Features and Construction

The kit is built around the core function of HDMI colour sync, using a dedicated controller and junction box to process video data. The LED strip is 2 metres long, covering most screens up to around 55 inches.

HDMI Sync Technology

The junction box reads the video signal from your source device and sends colour data to the controller, which adjusts the RGB LEDs accordingly. The included 0.3m HDMI cable is rated 2.0V 4K*2K, supporting high-definition passthrough.

Size and Practical Fit

The controller box is compact at 160×90×20mm, fitting neatly behind most TV stands or desks. The 2-metre LED strip provides even coverage around the perimeter of typical displays.

Power Requirements

The controller operates on DC12V input, while the junction box requires a separate 5V 1A power supply. Neither power supply is included, so you will need to source them separately. Working temperature range is -20°C to 60°C.

Uses and Placement

This kit is designed for indoor use on TV and computer displays, adding ambient light that matches the content on screen. It works for both daily viewing and dedicated gaming or film setups.

Home Cinema

Connecting the kit to a TV creates a cinema-like effect where the light behind the screen changes with the scene, reducing eye strain and increasing immersion.

Gaming Setup

For computer monitors used for gaming, the real-time colour sync adds atmosphere and can make fast-paced action feel more engaging. The 2-metre strip fits standard desk monitors.

Everyday Desktop Use

Beyond gaming, the kit can be used for general computing, adding subtle ambient light that matches the desktop background or video content.

Benefits and Buying Value

The main advantage of this system is its automatic colour matching, which requires no manual adjustment once set up. The included components cover the essential hardware, though you will need to supply two power adaptors.

Easy Installation

The kit uses a standard HDMI connection and adhesive-backed LED strip, so you can set it up in minutes without specialist tools. The compact controller hides out of sight.

Versatile Use

Works with any device that outputs via HDMI, including set-top boxes, games consoles, PCs, and streaming devices. The 4K*2K compatibility ensures it works with modern displays.

What Is in the Box

The package contains the junction box, a 0.3m HDMI 2.0V 4K*2K cable, and a 5V 1A power cord for the junction box. The LED strip and controller are included, but you will need to supply the DC12V power supply for the controller and the junction box power supply.
