2. Attach the Light Strips
Carefully peel off the adhesive backing and paste the light strips in order around the perimeter of your TV. The 12.5-foot light strip consists of two parts and can be securely mounted on all four sides of 55-65 inch monitors using the included clips and adhesive. Each side is connected with a flexible cable. You can adjust the length of the light strip by cutting it between every 3 LEDs.

3. Connect the Sync Box
Connect your signal source (e.g., laptop, set-top box, gaming console) to the HD IN port on the HDMI sync box. Then, connect your TV or PC to the HD OUT port. Ensure all connections are secure. Finally, connect the power adapter to the DC 12V port on the sync box and plug it into a power outlet.

Operating Instructions
Powering On/Off
Use the remote control or the PWR/MODE button on the sync box to turn the device on or off.
Color Synchronization
The 4K @ 60Hz HDMI box automatically captures colors from your screen via the HDMI signal and applies them to the TV backlight. This provides full color synchronization with no noticeable delay, creating an immersive viewing experience.
