Questions about PI3d PictureFrame

I'm trying to learn about PI3D PictureFrame capabilities. Is this a good place to ask? If not, where?

Questions include:

1) Does it handle a mixture of portrait and landscape photos and autorotate them?

2) What does it do if the picture doesn't fill the screen? Is there some sort of a blurred matt that I see other picture frames do? Or is it just black?

3) Does it ever put two portrait photos side by side?

Thank you in advance.
