TV Backlight Buying Guide: Light Sync for Consoles, TVs and Monitors (2026)

A light strip behind your TV that extends the colours of the picture onto the wall makes the screen feel bigger. Philips builds this into its own TVs as "Ambilight". For every other TV and monitor there are retrofit kits. The key question when buying is not brightness but how the kit reads the on-screen colours: with a camera, an HDMI sync box or software on your PC. That decides whether TV apps work and whether your console keeps running at 4K 120 Hz with VRR.

Transparency: We have not tested these kits ourselves. Technical data comes from Philips Hue, Govee, Nanoleaf and the Amazon.de product pages we checked (October 2026). We deliberately leave out prices because they change all the time.

Three ways to read the picture

1. A camera on the TV

A small camera sits at the top centre of the TV, films the picture and passes the colours to the LED strip. The big advantage: it works with any source, including Netflix, YouTube and other apps running on the TV itself. You don't have to change your HDMI setup.

The downsides: the camera needs calibrating and can be affected by light in the room. Govee recommends mounting it on top so a ceiling light isn't reflected on the screen and doesn't throw off colour detection. According to Govee, its kit does not support curved TVs.

2. An HDMI sync box

Your console, PC or streaming box no longer plugs straight into the TV but into a box. It reads the colours directly from the HDMI signal and passes the picture on to the TV. That is precise and unaffected by room lighting. The catch: apps running on the TV itself are not detected. Philips states clearly that the sync box only works with HDMI devices.

For gamers, what the box passes through is what counts. A box with HDMI 2.0 becomes a bottleneck for a PS5 or Xbox Series X. Look for HDMI 2.1, 4K at 120 Hz, VRR and ALLM. The gaming TV buying guide explains what these terms mean.

3. Software on the PC or TV

On a PC, an app does the colour detection: the light strip connects to the computer over USB (Nanoleaf), or the app controls existing smart lights (the Philips Hue Sync desktop app for Windows and Mac). Some TVs don't need any extra device: according to Philips, the Hue Sync TV app runs on Samsung QLED TVs from 2022 onwards (Q60 or higher) and on LG TVs from 2024 with webOS 24.

What to look for

Strip size and length

Kits are sold by screen size. According to the Amazon listing, Govee offers the TV Backlight 3 Lite with 1.8 m for 32 inches, 2.4 m for 40–50 inches, 3.6 m for 55–65 inches and 5 m for 75–85 inches. Pick the version that matches your TV, not the longest one.

Distance to the wall

The light effect needs a surface. Govee names 10 to 20 cm between TV and wall as ideal. A TV on a flat wall mount or standing in the middle of the room gives a weaker effect. According to Hueblog, the light also shows up more strongly on light-coloured walls than on dark ones.

Control and ecosystem

Govee kits run through the Govee Home app, Philips Hue through the Hue app, and the Nanoleaf strip only through the Nanoleaf Desktop App. The systems don't mix: Govee says its AI Sync Box only works with Govee lights, and the Hue sync box only syncs Hue lights. If you already own lights from one brand, it's best to stick with it.

Wi-Fi

According to Govee, its camera kit needs 2.4 GHz Wi-Fi; 5 GHz is not supported. Hue lights communicate via Zigbee or Bluetooth, according to Philips.

Five example kits

The following kits are available on Amazon.de. They are not test winners but examples of the three approaches. All were in stock when we checked (October 2026); seller and shipping are noted for each.

Example model

Camera kit for TV apps: Govee TV Backlight 3 Lite (55–65 inches)

A camera with fish-eye correction and a 3.6 m RGBICW strip, meaning colour LEDs plus an extra warm-white chip. Govee says the kit fits TVs that are 4 to 35 mm thick, but not curved TVs. When the camera detects a blank or static picture, the lights switch off automatically, according to Govee. With DreamView you can sync up to seven more Govee lights. Sold by Govee EU, shipped by Amazon.

TV size: 55–65 in (3.6 m)

Govee quotes up to 8K at 60 Hz and 4K at 144 Hz, plus VRR and ALLM.

How to decide

Do you watch a lot through apps on the TV itself? Then a camera kit or, on Samsung/LG, the Hue Sync TV app. An HDMI box can't see that content.
Do you mainly play on a console or PC over HDMI? Then an HDMI 2.1 box that passes through 4K at 120 Hz and VRR. You'll need suitable HDMI 2.1 cables for the connection.
Do you play on a PC monitor? Then a USB strip with a desktop app is the easiest option.
Do you already own smart lights? Stick with the same brand, because the systems don't mix.

If what you really want at your desk is better lighting rather than effects, a monitor light bar is the better choice.

FAQ

Does an HDMI sync box work with Netflix on the TV?

No. The box only sees what comes in over HDMI. Philips points out that apps running on the TV are not supported. For TV apps you need a camera kit or an app on the TV, such as the Hue Sync TV app on compatible Samsung and LG models.

Will a sync box cost me 4K 120 Hz on my PS5?

Not with an HDMI 2.1 box. Philips says the Hue Sync Box 8K passes through 4K at 120 Hz, VRR and ALLM. The older Hue Sync Box 4K only handles 4K at 60 Hz and 1440p at 120 Hz, according to Philips.

Do I need a Bridge for Philips Hue?

Not for the Sync Box 8K with a single supported light such as the Play Gradient Lightstrip, according to Philips. If you want to sync several Hue lights, Philips recommends a Bridge.

Does a camera kit work on a curved monitor or TV?

Govee says the TV Backlight 3 Lite does not support curved TVs. For curved monitors up to 32 inches, Nanoleaf lists the PC Screen Mirror Lightstrip as suitable.

How far should the TV be from the wall?

Govee names 10 to 20 cm as the ideal distance. Too close and the glow stays small; in the middle of the room there's no surface for the effect.
