Wireless Screen Sharing

Why be limited to a small monitor when you can use a big screen? View your computer, your meetings, all from your Smart TV. 


Want to allow a screen share of your student’s phone or device screen to the big screen in a classroom? Start a Zoom meeting on a device (desktop, laptop, phone) connected to the classroom projector.

  • On the second device (PC, Mac, or mobile device) that you wish to mirror, open a browser and go to share.zoom.us 
  • Enter the meeting ID or personal link into the prompt. 
  • Select the desktop or application to screen share. 
  • Click the Share Screen button. (Note: check the Share Computer Sound checkbox if you want the mirrored screen audio to also play audio. 
  • Your screen will be shared with the members of the Zoom meeting. 

Using Chrome (COMPUTER) 

Consider using the Google Chrome browser CAST feature to share the screen of a different device.

Casting and Airplay (MOBILE) 

Depending on the mobile device you are using, you may run into some issues for doing screen mirroring. 

If you are using an iPhone, your options are more limited when it comes to casting your device. Unlike Android devices, you may not be able to use the function of screen mirroring the phone. Using an Apple TV, you can utilize Airplay to fully mirror your screen including FaceTime calls, movies, music, and more. Without an Apple TV device, you are limited about what you can share. Instead, there are certain apps that allow for casting capability. This means that when you open up the app and start to play music or video, there will be a Cast option that will let you share the media with a much wider variety of devices, such as Chromecasts and Smart TVs. These apps include: 

  • YouTube 
  • Spotify 
  • Pandora 
  • Most streaming services (Netflix, Hulu, HBO, etc.) 

If you are using an Android, full screen mirroring is easy and compatible with most smart devices, including Smart TVs. To perform the operation, the steps are as easy as one, two, three! 

  • Drag open your quick settings panel from the top of the screen. 
  • Tap the Screen Cast button; you may have to swipe to a different page. 
  • Tap the device you want to cast to. Mirroring should begin! 

Mirroring can be stopped from the same place. 

With Android, you also have the option to directly cast video from a multitude of apps. This list includes everything from the iPhone list as well as more.
