Action's HDMI sync box is now on sale, offering an affordable way to enjoy an Ambilight-like experience on any TV. This week, the price dropped from €32.95 to €26.95, making it a budget-friendly alternative to expensive Philips TVs or camera-based systems.
The sync box analyzes the HDMI video signal to project matching colors onto the wall behind your TV, creating an immersive effect. Unlike traditional LED strips that show static colors, this kit provides real-time dynamic lighting that syncs with movies, games, and shows.
What Is an HDMI Sync Box and How Does It Work?
An HDMI sync box is a device that sits between your video source (like a console, streaming stick, or set-top box) and your TV. It reads the video signal and sends color data to an LED strip placed behind the TV. The strip then lights up with colors that match the on-screen action.

This creates a bias lighting effect that extends the image beyond the screen, similar to Philips' Ambilight technology. The key advantage is that it works with any TV, not just Philips models.
Action's Sync Box: Features and Pricing
The Action sync box comes with an HDMI sync unit and an LED strip. It supports HDMI pass-through, so you can connect multiple devices via a switcher if needed. The LED strip is adhesive and can be cut to fit your TV size.
At €26.95, it's a steal compared to dedicated Ambilight TVs, which can cost hundreds more. However, availability may be limited, as Action is a discount retailer with fluctuating stock.
Amazon Alternative: WiZ HDMI Sync Box
If you can't find the Action box or it's sold out, the WiZ HDMI Sync Box is a solid alternative. It's currently priced at €45.90 on Amazon, almost half off its regular price. This kit supports TVs from 55 to 65 inches and is compatible with Alexa, Google Home, and Apple Home.
The WiZ system also analyzes the HDMI signal in real time and can display multiple colors simultaneously across different zones of the LED strip. This allows for more dynamic effects that match the action on screen.

Why It Matters: The Appeal of Bias Lighting
Bias lighting isn't just a gimmick; it can reduce eye strain by softening the contrast between the bright screen and dark room. It also enhances perceived picture quality by making blacks look deeper and colors more vibrant.
For gamers and movie lovers, synced lighting adds a new dimension of immersion. Explosions in games or dramatic scenes in movies feel more impactful when the room is bathed in matching light.
Previously, achieving this effect required either a Philips Ambilight TV or a camera-based system like the Govee Immersion. Both options are more expensive and, in the case of cameras, can be intrusive.

Who Should Consider This?
If you have a standard TV and want to add Ambilight-like effects without breaking the bank, the Action sync box is a great entry point. It's also ideal for those who don't want to mount cameras on their TV.
For users with larger TVs (55-65 inches) and smart home setups, the WiZ box offers more features and integration. However, it costs nearly double the Action box.
