Sync on a philips lightstrip tv when other gradient strip is connected

Hello
My installation is composed with 1 gradient strip light Philips I use for ambiant only and 1 strip light tv 75" Philips I want to use for tv sync.
I have tried the theater demo on my installation but this is the wrong strip which get the sync, the gradient strip , not the tv strip. First question : does the tv strip light is suitable ? (I suppose it’s the same type of light than gradient light strip ?)
Second, if first response is positive, where set up the good strip to sync with the one we want when we have many strip ?
thanks !
