How does the Display Profiles work?

Hi,
I want to make a game in the Landscape format but I don’t know If It’s Landscape or Portrait.
When I debug the game It’s in the Portrait format I think because the screen is not full screened with my scene(black frames at the top and bottom).

How Can I fix this?

Debug builds work differently than release builds in relation to this I believe. Test a release build and see if it behaves how you want. You can also edit the manfiest / plist to force only allowing landscape orientations.

How does it look if the Display is in Landscape mode?
