Share Desktop in Virtual Classroom


Explains how to share your screen in the Virtual Classroom meeting space when using Chrome.  Users completely new to Virtual Classroom may want to read the general overview here. Also, please be sure to review our Basic System Requirements, Bandwidth Requirements and  Common Troubleshooting Solutions.

Pro Tip

The required bandwidth to use or watch the desktop share feature can be higher or lower depending on the content being shared. If you are experiencing network issues or poor performance, you can disable this feature within the Virtual Classroom Settings. Please note that changing this setting will only affect your view of the session, not others.

In Virtual Classroom meetings, you may want to share your screen with other participants*.


  • When using a 4K display, some users have found they need to disable their HDR settings to share their screen successfully. Experiment with these settings if you experience issues when sharing a 4K screen.

If your computer currently uses Mac OSX 10.15 “Catalina” or a newer version, you need to explicitly allow your browsers to record your screen. This permission will only need to be accepted once.

  • When you open screensharing in Virtual Classroom, you will see a dialog like this one:
  • Select “Open System Preferences"
  • In the menu on the left, scroll down and click on Screen Recording.
  • In the window on the right, make sure the box next to your browser is checked.
  • Quit and re-open your browser to apply the changes, and your system will now allow screenshare in Virtual Classroom.
Sharing from a Browser Window
Instructions for how to share your screen from a browser window.

To share a browser window and allow for tab switching, select window. To share only one tab, select Tab (may appear as Chrome tab, Firefox tab, or other depending on browser). 

Click Share to begin sharing your screen. Other participants will now see the Browser window or tab that you have selected. 
Sharing from a Desktop App

Instructions for how to share a screen from an application.

Click the Share Desktop icon.


You can share Your Entire Screen (recommended*) or Application Window. Select your preferred option and Share.

*Certain applications may not refresh quickly enough to display your actions. 



When you share your entire screen (if you're sharing the same screen where you're using the Virtual Classroom meeting), you may see an "infinity effect" where the screen repeats itself within the presentation space. This is normal and will not affect the performance of other Virtual Classroom features.

Other Virtual Classroom participants will now see what you're sharing. 

Sharing videos with sound in Virtual Classroom

To send audio with your screenshare, make sure you're using Chrome (or Edge, version 80 or higher), and select the browser tab that contains the video you'd like to share. Then, click the checkbox in the lower left corner of the dialog box to enable audio.


Switching between screen-share and uploaded presentations

After uploading your presentation, you are able to share your desktop at the same time and switch between the two screens by clicking on the View Presentation/View Screenshare button. 


When you’re done sharing, click the Exit desktop icon.
