I am using iPad 3 and I try to use 30-pin Digital AV adaptor for mirroring on my Samsung HD TV. Unfortunately it is not a full screen projection. Anyone can help?

What are you mirroring?

If it is just the iPad screen then, since the proprtions of the iPad screen are not the same as the Samsung TV, the image cannot fill the screen.

Have you used Netflix or some other App which can use the Samsung proportions In HD movies, etc?

It may be due to the different aspect ratio. The iPad is 4:3 and the Samsung is 16:9

The iPad Screen is almost square, HD TVs are rectangular so will never be full screen. When watching movies, the movies native aspect ratio will be used rather than the iPads screen aspect ratio so will look full screen if the movie is full screen, but most likely will be seen in wide screen letter box format. with black bars across the top and bottom as that what most movies from iTunes are in, format wise

Did anyone read my post? 😉

I did and I liked it.

If u can alter the screen aspect on your tv then this is the only option you have to increase the size.
