16:9 - Design Setting

I have 35 anroid tvs, but since android is unlicensed, I cannot adjust the screen rotation settings. The screen is in the form of a horizontal tv, and in the fixed settings, there are no vertical settings malasef, my goal is to use this TV vertically, how can I make a 16:9 design. I will use the TV vertically for movie posters and movie theater session operations.
