When you're in a classroom and need to project, connect your PC (or laptop) using the provided cable connections in the room. Once everything is connected, press the Windows key + P, and then choose one of the four options:
PC screen only. You'll see everything on your PC.
Duplicate. You'll see the same things on both screens.
Extend. You'll see everything across both screens, and you can drag and move items between the two.
Second screen only. You'll see everything on the connected screen. The other screen will be blank.
If you are still unable to connect to the screen, please raise a support request with our team and we will be happy to help.
