TV that moves with you, wherever you are in the home.
✔ Wirelessly connect Sky Q Mini Box to watch on an additional TV. No mess. No Fuss.
✔ Pause the action on one TV and pick it up exactly where you left it on another. Or on your mobile, tablet or laptop.
✔Take the TV you love wherever you go. If your shows are recorded on your Sky Q box, they’re in your Sky Go app too.
