What is the software for displaying images in different windows?

Question

Monitors

Hello. There is a problem, there is a media panel on which the laptop is connected via an HDMI cable. Everything is set up, everything works. But for people who will show presentations, videos on it, the win + p key combination is inconvenient, they want the person who sits at the laptop to see what is on the laptop monitor and what is on the media panel (since he is sitting behind the wall and this very does not see the media panel). Is there any software for this? I hope I didn't confuse)

Answer 1

Hope I didn't confuse

There are a few :)
The proposal is this: use not software, but hard. Such a thing: https://www.google.com/search?q=hdmi+splitter
With one tail in the laptop, the other in the panel, the third in the additional monitor (next to the laptop). And there will be the same picture on the monitor as on the panel.

Answer 2

Put a webcam in front of the panel and watch the regiment from the camera
