The AmbiMotion 2.1 Pro is the step up from the 2.1. Three HDMI 2.1 inputs instead of one, with an upgraded sync box and LED strip behind it. The 2.1 is the single-source kit; the Pro is built for a full living room setup.
Both are genuinely good. This guide is about which one fits what you actually run, and answering the questions people ask us before they buy.
What both kits give you
Every AmbiMotion 2.1 kit is full HDMI 2.1, and passes everything through untouched:
- 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 unchanged
- VRR — no screen tearing when frame rates fluctuate
- ALLM — your TV drops into game mode on its own when the console starts
Both cover 27 to 120 inches across three size variants, run on the Smart Life app, and work with Alexa and Google Assistant.
Where the Pro pulls ahead
Three HDMI 2.1 inputs, not one
This is the difference you'll feel every day. A sync box reads the video signal on its way to your TV, so whatever you want the lighting to follow has to be plugged into the box.
With one input, you choose. Your console gets the lighting and the set-top box doesn't, or the other way round. The other device still works on your TV — it just won't drive the lights. Most people discover this after installation, when they switch from gaming to a film and the wall goes static.
The AmbiMotion 2.1 Pro takes console, set-top box and streaming stick together, all at full 2.1 spec on every port — not one 2.1 port and two older ones, which is what most multi-input boxes actually give you. Everything stays plugged in, and the lighting follows whichever input your TV is showing.
An upgraded box and strip
The Pro isn't the 2.1 with extra sockets. It's built on a different sync box and a different LED strip, specified for larger screens and brighter rooms. On a 65-inch panel and up, that's where you see it — colour that reads as a lit wall rather than a glow around the edges.
When the 2.1 is the right call
If everything you watch comes through a single device — one Fire TV Stick, or just a console — the AmbiMotion 2.1 covers it for less money, and we'd rather you bought that than paid for ports you'll never use.
It's also the sensible choice on a smaller screen, where the Pro's extra output isn't doing much work.
Two devices is the genuine grey area. If you rarely switch, plug the main one in and the 2.1 is fine. If you game three evenings a week and stream the other four, you'll be reaching behind the TV unit constantly, and the Pro pays for itself in convenience alone.
Questions we get before people buy
Will it reduce my picture quality?
No. The signal passes through untouched on both boxes — same resolution, same refresh rate, same HDR format reaching your TV. Dolby Vision and Dolby Atmos survive the trip on every port.
Does it add input lag for gaming?
No. An HDMI 2.1 box passing the signal through adds no meaningful latency, and ALLM means your TV switches into game mode automatically. The lag complaints you read about almost always come from camera-based systems or boxes that force a console down to a lower mode.
Will it work with my TV?
Any TV with a spare HDMI input works, smart or not — the box handles the signal, so the television doesn't need to do anything clever. For full 4K 120Hz you also need an HDMI 2.1 port on the TV itself; many mid-range sets have 2.1 on only one or two ports, so check which one you're using.
Do I need an external device plugged in?
Yes, and this is the one people most often get wrong. Apps built into your smart TV don't pass through the sync box, so they can't drive the lighting. Netflix, Prime Video and Hotstar all sync normally — but only when played from a Fire TV Stick, console or set-top box connected to the box. Do I need a Fire TV Stick for a TV backlight? covers this properly.
Which size do I order?
Measure the back panel of your TV around all four edges, not the diagonal on the box. Screen size and back panel size aren't the same number, and this is the most common ordering mistake. Three variants cover up to 65 inches, 65 to 90, and 90 to 120.
Is installation difficult?
Peel and stick around the back panel, plug your devices into the box, run one cable to the TV, pair it in the app. Clean the back of the TV first — dust is the difference between a strip that stays up for years and one that peels in a month. Our team in Amritsar sends a setup video if you want one.
Can I upgrade later?
The Pro uses a different sync box and strip, so moving up means a new kit rather than swapping the box. If three devices is where you'll end up, it's cheaper to start there.
