IOS screen mirroring displays restrictions on selected applications

Question

Problem: iPhone screen mirroring and the highlighted appearance of my application show an inch of black border on all sides.

But: some views are displayed perfectly without black borders in full screen mode, for example, in the Apple TV menu and the photo application.

Tried it already - no effect:

• Disabled switching to 1080p HD TV ("Disable 16: 9 overscan") ( iPad Mirroring using 2 screens, does it support 1080 pixels? )
• set UIScreenOverscanCompensation - has no effect ( IOS - External (hdmi) output fills only half of the screen, except when the encoding is manually displayed )

Setup: iPhone 4S (5.0.1), 2nd Generation Apple TV (4.4.4)

Any suggestions I could try extra?

Answer 1

Go to the same problem, and it took some time to find a "solution". Turns out you can set overscanCompensation to "3" and it will remove the borders.

I think that Apple simply refused the documentation and listing for UIScreenOverscanCompensationNone, but this is in the code that they are checking.

Answer 2

If you also have black borders during AirPlay Mirroring, MobileVet's answer will not solve this. Try changing the following settings on your Apple TV: Settings> Audio & Video> Configure for AirPlay Overscan. Set to Off (enabled by default).

And btw: not 3 just means UIScreenOverscanCompensationInsetBounds | UIScreenOverscanCompensationApplicationFrame (1 + 2)?
