Attention! If you use the TV DVT tuner or play Netflix & Co. directly via an app on the TV, you will be left out in the cold. In this case, colour synchronisation is NOT possible. Because the signal must go through the Hue HDMI Sync Box, i.e. a Set-Top Box is also necessary - this is nonsense with new TVs! I find this really very weak and Philips does not make this clear at all.
