Operating Classroom AV
For most classroom AV setups, you can connect to the projector using the classroom iMac, the Laptop HDMI cable, or wirelessly using the Apple TV. Jump to the section that describes how you you wish to connect, and follow the step-by-step instructions.
Connecting using the iMac
2. Select iMac on the AV switch
3. Log in to iMac with your netID/password
- Troubleshooting tip: if you are using a Mac and getting an “extended desktop” on the projector screen, you may need to “mirror” your displays. To change your display settings in macOS Ventura, go to > System Preferences > Displays. Choose the Built-in display and under Use as, choose “Mirror for VP-XXX”
4. Please turn off the projector when you are finished. Note: Some of the projectors have separate On and Standby buttons instead of a single On/Off button.
