What sets this apart is that it uses the feed directly from the receiver—no bulky camera stuck to the top of the TV like other brands. Setup was super easy, and my whole family is obsessed with how much bigger and more immersive it makes the TV feel. I previously had a similar model from another company, and it was just okay. This one, though, looks fantastic—clean, bright, and way more accurate with the colors. The clip I shared is from one of the best scenes in Game of Thrones (Battle of the Blackwater), and this was filmed at 2 PM with the lights on. It looks even brighter and more incredible in a dark room. If you're on the fence, this is the one to get.

I know back lighting has been around for a while, but this device syncs perfectly with the content on the screen. Whether it’s sports, news, or movies, it doesn’t take away from the content on the screen. Note that the 3-port option does not provide automatic HDMI switching. Save your money and just buy this model and invest in a good quality automatic HDMI switcher. HDMI Devices -> HDMI Switcher -> Fancy Box -> TV

📺 Smooth 4K120 passthrough with fun ambient lighting The Fancy LEDs HDMI 2.1 sync box works well with my setup and handles 4K 120Hz without issues. The lighting reacts quickly and adds a nice boost to movies and games. ✅ Pros: Genuine 4K 120Hz passthrough with HDR support Lighting reacts fast and matches the screen accurately Setup is straightforward with clear instructions Works well for both movies and gaming Good brightness on the included LED strip ❌ Cons: App can be a little slow to connect at times LED strip adhesive could be stronger Best results come in darker rooms, not as effective in full daylight

Love the Fancy Sync Box. The lights look amazing, the app to contol them is great and has a very wide range of ajustment. Lights were easy to install. One thing I noticed that even I installed the lights correctly, staring from the left bottom corner, following to the top left corner, on the app lights are only corectly syncronised when i choose the opposite direction. Kind of strange but not a big deal. Also this box has only one HDMI input. Would love if it had at least two inputs.

Excelente producto, muy fácil de instalar y configurar, los colores son muy precisos y el costo muy accesible en comparación a los HUE de phillips, no todas las películas lo aprovechan, seria para películas de ciencia ficción y vídeo juegos ya que es compatible con Vrr y allm para aprovechar al máximo el HDMI 2.1.
