The 2.1 Fancy Sync Box is the world's first HDMI 2.1 sync box with true HDR syncing. A dedicated HDMI 2.1 chip reads the HDR color on screen accurately and drives the included RGBW LED strip to match, so the wall behind your TV glows with whatever you're watching or playing. Your picture passes through untouched. Games run at up to 4K 144Hz on next-gen consoles, movies at 8K 60Hz, and HDR and Dolby Vision are preserved end to end. VRR (Variable Refresh Rate) switches dynamically between 144Hz, 120Hz, and 60Hz, ALLM (Auto Low Latency Mode) reduces lag for smoother gameplay, and HDMI-CEC lets you control your TV and light settings from one remote. Connect a console or streaming stick to the single HDMI input and the LEDs react instantly, saturated with real on-screen color. How It Works Connect your HDMI device — a console or streaming stick — to the sync box. Run a single HDMI cable from the box to your TV. Mount the 96 LEDs Per Meter RGBW smart LED strip behind your screen — the lights follow the on-screen color instantly.

FAQ Does the 2.1 Fancy Sync Box support 4K 120Hz and 144Hz gaming?Yes. It passes video through at up to 4K 144Hz — including the 4K 120Hz used by the PS5 and Xbox Series X — with VRR switching between 144Hz, 120Hz, and 60Hz and ALLM keeping input lag low. For video, it supports 8K at 60Hz. Will Netflix, Disney+, and other streaming apps work through it?Yes. The box is HDCP 2.3 compliant, so DRM-protected content plays and streams normally. Does it support eARC?No. ARC is supported; eARC is not currently supported. Can I use it with a PC or computer monitor?No. This model is designed for TVs and isn't compatible with PC monitors. What do I need for the lights to sync?An HDMI source — a console or streaming stick — connected to the box's HDMI input. The LEDs follow that HDMI signal, so syncing needs an active source. How many devices can I connect?This model has a single HDMI input for one device. If you want to connect several devices at once, see the 3 Port 2.1 Fancy Sync Box. How long does delivery take?Orders are processed in 1–3 business days. After dispatch, delivery is typically 2–6 business days in the US and 4–10 in the UK, EU, and Australia. Shipping is free to the US, UK, EU, and Australia. Will it add input lag or lower my picture quality?No. The box is a true passthrough — your resolution, refresh rate, HDR, and Dolby Vision reach the TV unchanged, and ALLM keeps latency low.
