Samsung Odyssey G60SD - How to get RGB leds to follow on screen picture?

Im really fond of the infinity core lighting feature.
But no matter what I do, the "core sync" feature is greyed out. How do I get it to work? I think its supposed to be able to follow the screen image, like on the Philips monitors? - No info in the user manual as far as I can see.

Does the USB-hub have to be connected for this to work? Or some software installation from samsung?

Im on latest firmware.
