Skeptical because of many complaints about switching sources when connected directly to the TV.
But works perfectly in combination with a receiver!
I use a separate receiver for the sound and the other connected equipment.
In my case, nothing is connected directly to the TV.
The sync box works perfectly this way.
You connect the sync box to the HDMI out of your receiver (output of the cable that runs to your TV) with the supplied cable.
Then you stop the hdmi cable that came from your TV (and you have now disconnected in hdmi 2 or 4 of the syncbox these port(s) support dolby vision etc)
Now you can switch sources with remote control on your receiver.
This works perfectly for me. Xbox one, PS4, Blu-ray player, and set-top box (ziggo) all work perfectly.
Via the sync app you indicate which lamps you want to play with. You can also choose movies or games etc. And control the strength and intensity in the app.
Dolby atmos / vision, hdr and hdr 10 plus work perfectly.
Do you want light effects with Netflix? Then start Netflix via, for example, the Xbox or PS4, then you also have light effects there.
In combination with the new Philips gradient LED strip, it is a pleasure. And certainly an extra experience, especially with movies and games.
