I want to display the vertically long camera image on the monitor in full screen.

I want to display the vertically long camera image on the monitor in full screen.

How should I set it?

Here's what I've tried:

I rotated the zoom camera setting of the image sending side by 90 degrees.
The monitor on the side receiving the image was set to portrait display.

However, due to the influence of the margin part, it was not possible to display it in full screen.

By the way, Android can display vertically well.

But I want it to succeed between windows.

thank you.
