I have the little Apple TV box to mirror my iPad onto the TV. However I've not used it for nigh two years now and, for the life of me, I can't remember how to make the icon appear on my iPad. I've googled it but advice is very sketchy and vague.

Anybody got any tips please? It's switched on, screensaver showing, password fed etc but the vital connection between the iPad and TV via this contraption cannot be made until they are linked up. Thanks.

Do you mean so you can view your ipad on the tv? Swipe up from the bottom and then transfer to your tv

Hope this helps

App Store and download the Remote app.

As above, you use AirPlay on your iPad, which can be accessed by swiping up from the bottom, or you should see the icon (which looks like a TV) at the bottom of the screen when playing a video.

You have to be signed in using the same ID, and I think Home Sharing needs to be turned on.
