Mitsuko Ambimotion 2.1 Pro TV Backlight Kit with 3 HDMI 2.1 Ports in HDMI sync box

The AmbiMotion 2.1 Pro is a TV sync backlight kit built around a three-port HDMI 2.1 sync box. The box reads the video signal travelling to your TV and drives the LED strip to match it — so the wall behind your screen changes colour with the picture, in real time, on whichever source you're watching.

Three HDMI 2.1 ports, so nothing gets unplugged

Most TV backlight kits give you one HDMI input. That means picking which device gets the lighting — console, set-top box, or streaming stick — and swapping cables for the rest.

AmbiMotion 2.1 Pro has three HDMI 2.1 inputs. Your PS5, your Jio or Airtel box and your Fire TV Stick all stay connected, all at full 2.1 spec, and the lighting follows whichever one you're watching.

A full HDMI 2.1 sync box on every port

Not one 2.1 port and two older ones. All three handle:

• 4K at 120Hz — full spec for PS5, Xbox Series X and high-end PCs
• 8K at 60Hz — headroom for 8K sources
• Dolby Vision and Dolby Atmos — picture and sound pass through untouched
• VRR (variable refresh rate) — eliminates screen tearing in games with fluctuating frame rates
• ALLM (auto low latency mode) — your TV switches into game mode automatically the moment you start playing

ALLM is the one people notice day to day. No diving into TV settings before each session — the console tells the TV, the TV switches, and you play.

If you're buying for a console specifically, Best sync box for PS5 and Xbox Series X in India covers what a box has to pass through and why HDMI 2.0 kits fall short.

The brightest strip we make

60 LEDs and 28 chips per metre — around 50% more than a typical TV backlight. More chips means colour blends into a smooth wash instead of showing individual dots, and it holds up in a room that isn't pitch dark.

On a large screen, that density is the difference between a visible glow and a wall that actually looks lit.

How it works

The Hdmi sync box sits between your devices and your TV. Your console, set-top box and streaming stick plug into the three inputs, and one HDMI cable runs from the Hdmi sync box to the TV. Everything travels through the box, so it can read the picture and drive the lighting to match — with no transition delay.

You need an external HDMI device plugged in. Apps built into your smart TV don't pass through the sync box, so they can't sync. Run Netflix, Prime Video and Hotstar from a Fire TV Stick or console instead and everything syncs normally.

Smart sync algorithm

The Hdmi sync box lighting algorithm picks the dominant colours in each frame rather than averaging everything into mud. Fast-paced films and quick camera movement still read clearly on the wall instead of turning into a muddy brown wash.

Movie mode follows the picture smoothly. Gaming mode reacts faster for fast action. Music mode responds to audio instead of the screen.

Syncs your whole room, wirelessly

Fantasia wireless sync connects other Mitsuko lights to the AmbiMotion Hdmi sync box — light bars, floor lamps, ceiling lights and wall lights all take colour from the same screen. The room moves together instead of one glowing rectangle behind the TV.

Which size do I need?

Three variants cover 27 to 120 inches:

• Up to 65 inches — most living room and bedroom TVs
• 65 to 90 inches — large living room and home theatre screens
• 90 to 120 inches — projector screens and very large panels

Measure the back of your TV, not the screen diagonal. Run a tape along the back panel edge to edge and pick the variant that covers all four sides with a little slack at the corners. Screen size and back panel size aren't the same number, and this is the most common sizing mistake.

App and voice control

AmbiMotion 2.1 Pro runs on the Smart Life app, free on Android and iOS. Colours, brightness, scenes and sync modes are all controlled from your phone. It also works with Alexa and Google Assistant.

Installing it

1. Clean the back of your TV. The adhesive needs a dust-free surface — this is the difference between a strip that stays up for years and one that peels in a month.
2. Peel and stick the LED strip around the back panel edge, working one side at a time and using the corner clips at each turn.
3. Plug your console, set-top box and streaming device into the three HDMI inputs of the HDMI sync box.
4. Run one HDMI cable from the HDMI sync box to your TV. Use an HDMI 2.1 cable if you're running 4K 120Hz — an older cable will bottleneck it.
5. Power the box, pair it in the Smart Life app, and switch your TV to the HDMI input the box is on.

Common questions

Do I need three ports?

If you run a console, a set-top box and a streaming stick, yes — otherwise you're unplugging cables to move the lighting between them. For a single source, AmbiMotion 2.1 gives you the same 4K 120Hz performance with one input.

Will I lose Dolby Vision or Atmos?

No. Both pass through the sync box untouched on all three ports, so you keep full picture and sound quality.

Which app do I need?

Smart Life, free on the Play Store and App Store. Our monitor products use different software, so make sure you're downloading the right one.

Does Netflix sync?

Yes, as long as you play it from a device connected to the sync box rather than the TV's built-in app.

Will it work on a curved TV?

Yes. The strip flexes along the panel edge. Measure the back panel as you would with a flat screen.
