Hi Julian,
You will need to force the x3 into 3d mode somehow to turn the glasses on and get them to sync.
Do you know what sources are connected? If you have a 2d to 3d option in a source that should be ok.
Let me know how you get on with X3, was working on an X7 at the weekend, the offset controls were a bit ugly and corse and introduced visable colour shifts at low ire’s with jusy a single click. I remember on the THX course we ended up with areally blue 10ire.
