I love my new iPad and am still getting used to what it can do. I have loads of photos on it as its a great way to show to friends and family. I would also like to connect the iPad to the TV and do a slide show. How do I do this? I tried plugging it in using the USB but didn't work. Do I have to get the apple box for about Â£80 o r is there another way to do it? The TV is a HD Panasonic. Help?
