Using Duplicate Displays vs. Multiple Displays
Click here to watch a demonstration video for using this feature
When presenting in the classroom, it is useful to know the different ways your computer can interact with the classroom projector. There are two main ways of interacting with your projector; Multiple Displays and Duplicate Displays.
Duplicate Displays, which in many cases may be the default mode you use, shows an exact copy of what you see on your laptop on the projector screen.
Multiple Displays, on the other hand, will extend your laptop’s screen to a second window on the projector. This allows you to have different programs or windows showing to your student.
This may be especially useful when trying to view both your virtual students on Zoom, as well as you’re in-class activities.
Switching to Multiple (Extended) Displays
Start by making sure that your laptop is connected to your classroom projector and is showing on the projector screen.
- Right-click anywhere on the desktop and select "Display Settings"
- You will now see the Display settings screen.
If 1&2 both show up in the same box that means your screens are set to "Duplicate". - Scroll down until you see "Multiple Displays"
- Select the pulldown menu and choose "Extend These Displays"
Your displays will now change to extended mode. If you scroll back up to the top, you will now see two separate rectangles for 1 (your laptop) and 2 (the projector).
The side that Number 2 is on decides which direction you move your mouse to get to the program you are using onto the projector. You can move the box to the side the projector is on you in the room to make this process easier.
Now you are able to project your classwork while keeping Zoom open on your laptop.
When screen sharing on Zoom, just select the projector screen (2) when you are prompted after clicking the screen share button.
