Beovision 11-55 and 3D

just bought a pair of 3D glasses for a bit of fun really, but do I simply go onto the sky 3D channel and start watching, or is there an adjustment necessary?  If there is, what do I need to do, and when I have finished watching 3D, do I then have to readjust the TV again?

 

thanks

I had to ask Sky to turn 3D on. It doesn't cost anything!

Sorry, Chris, I phrased the question badly.  I meant what, if any, adjustments are needed on the TV

You can have 3D as an option on the Beo4 in "list" if I remember rightly, or by pressing list/list/picture again on the Beo4. Memory vague as I didn't use it that often.
