How to increase screen sharing in skype on debian?

Question

Skype

When Windows was on, when demonstrating the screen, Skype somehow very beautifully adjusted the broadcast, depending on the monitor of another person, that everything was very clearly visible.
When I installed Debian, Skype shows the area 2 times smaller than on Windows, so almost nothing can be seen.
I did not find any such settings.
Can you please tell me how to fix this?

Answer 1

Try " Hold ctrl and press +

Answer 2

How to understand 2 times less? Does the capture area occur in the center? Post a screenshot so it's not clear how you describe the situation.
