How to Mirror display in window 7 Pro

Hi guys!

I have a classroom with 25 desktops. I need to control the 24 pc, using the 25th which is the teacher’s pc. They are all networked.

I need to project my display to all of the 24 pc whenever I need to present something. The projector screen is helpful but not to the people seated at the back. So I was thinking just to project my display to all of their monitors.

I already come across with chromecast but this is casting using the browser. I need to cast my display to all monitors attached to the network. I dont have MS Miracast and I will not be casting wirelessly but wired.

All pc are wired connected to a cisco switch hub.

Any advise is much appreciated.

Thanks!
