Black bars with HDMI adapter on iPad 2

My application supports HDMI output.

I asked for a code for the resolution of the TV and got 1920 x 1080 px for

externalScreen.bounds

Ok, everything is fine. I adjusted my views and tried them on TV ...

BUT: There were black bars on the bottom / top / sides of the screen, although the TV was detected correctly, like 1920 x 1080, and my presentation is also set up correctly?

Why is the format wrong?

PS When I reflect the main screen, it also shows stripes, when I watch a video with the Youtube application, do the black bars disappear?

Thank you for your help!

Update:

OK, although I got this output in my console:

A new screen got connected: <UIScreen: 0x3439a0; bounds = {{0, 0}, {1920, 1080}}; mode = <UIScreenMode: 0x345240; size = 1920.000000 x 1080.000000>>

... I still get a black frame. I am starting to browse CGRectMake(0.0f,0.0f,1920.0f,1080.0f)for testing purposes.
