Setting up the Sync Box means connecting the HDMI chain, installing the Hue app, adding the box and creating an entertainment area. Connect each source, such as a console, streamer or player, to one of the four HDMI input ports and the Sync Box's HDMI output to the TV, using certified HDMI 2.1 cables for 4K 120 Hz and 8K 60 Hz; independent guides say an incorrectly ordered chain or a cable not rated 2.1 is the most common cause of no-signal states, and advise using short known-good cables.
The checks in more detail
Set the TV port to Enhanced format if it has such a setting. Power up in order: TV first, Sync Box second and source last. In the Hue app, add the Sync Box, follow the prompts to join wifi over Bluetooth 5 and link it to your Bridge, then create or choose an entertainment area, assigning up to ten Hue lights and positioning them relative to the screen. Pick a sync mode and intensity.
A separate entertainment area needs its own Sync Box. Do not use the TV's ARC or eARC port for the Sync Box input if you need that for soundbar audio. If setup stalls, restart the box and Bridge and try again. Update firmware after setup and test each source. Label each HDMI cable with the device name so you can retrace the chain later. If the picture is fine directly but not through the box, the chain or a cable is the cause.
Set up when you are not rushed. Test the chain at 1080p first, then step up to 4K and HDR one setting at a time, since that isolates the cable or port that cannot carry the higher mode. The box reads the HDMI signal and does not use a camera, so there is nothing to position in front of the screen, and the only positioning is where you place the lights in the entertainment area.

How to confirm Connect the source into the box and the box into the TV, not the other way round
- 2
A cable not rated for the mode
What separates it There is no picture at 4K 120 Hz because the cable cannot carry that mode
How to confirm Use a certified HDMI 2.1 cable for the highest video modes
- 3
The TV port not in Enhanced format
What separates it HDR does not work because the TV port used is not set to its Enhanced format
How to confirm Set the TV port to Enhanced format in the TV's settings, if the TV offers it

No entertainment area
What separates it Nothing syncs because no entertainment area has been created in the Hue app
How to confirm Create an entertainment area in the app and assign the lights to it

Using the ARC port
What separates it The soundbar has no audio because the box is connected to the TV's ARC port
How to confirm Use another HDMI port on the TV for the box, keeping ARC for the soundbar

Record this first — changing settings destroys the evidence
- How the HDMI chain is connected from source to TV
- The cables you are using and whether they are certified
- The settings of the TV port that the box is plugged into
- The entertainment area you have created

Exact questions
Common questions
Which port for the box output?+
Connect the box's output to a TV HDMI port, but not the ARC port if you use that port for audio.
How many lights per area?+
An entertainment area can have up to ten lights, so choose the ones that best surround the screen.
What order do I power up?+
The power up order is TV first, then the box, then the source, which helps the devices connect properly.
What cables?+
Use certified HDMI 2.1 cables, which carry the high bandwidth video that the box can pass through.
What if I get no signal?+
If you get no signal, test at 1080p first to rule out a cable or format problem.
Can one box do two areas?+
No, one box can do only one entertainment area, so a second area needs a second box.
Should I set Enhanced format?+
Yes, set Enhanced format on the TV port the box uses, if the TV has that option, so HDR modes can pass.
What is the operating temperature?+
The Sync Box operates between 0 and 40 degrees Celsius, so keep it out of hot cabinets.
What voltage is the adapter?+
The adapter supplies 12 volts, and you should use the adapter supplied with the box.
Does it support Dolby Atmos?+
Yes, it supports Dolby Atmos passthrough, so the audio reaches your soundbar or receiver unchanged.
Can I change intensity?+
Yes, you can change the intensity of the effect in the Hue app to suit the room.
What if the TV port lacks Enhanced format?+
If the TV port lacks Enhanced format, some 4K HDR modes will not pass through the Sync Box.
