Review: The lights were easy to set up and they look absolutely beautiful. Lots of light customization options with their app so I could tweak levels just to my liking. I can’t play video games anymore without these lights, they truly enhance the experience. Movies and shows pop as well. Definitely worth the purchase.
Review: 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
