There are two different options that can be used to set up a classroom display: Mirroring and Extending:
Mirroring means that whatever you see on your podium display is the exact same thing as what is shown on the front display of your classroom - when you move your mouse at the podium, the mouse moves on the front display screen as well in real-time.
Extending means that you essentially are using the second monitor as an extension of your desktop...in other words, it gives you more desktop to work with, and you can arrange what you want across the two screen the same way you can with one.
The video below demonstrates and explains how this works, and shows how to toggle between the two settings.
Here are written instructions for checking and changing the display:
 |
Click on the clock at the lower right corner of the screen and click the cog/wheel icon to enter the settings menu. |
 |
Click Device on the left side and then click Displays. |

Use the Mirror checkbox to toggle between Extended and Mirrored mode. |
