When sharing an application or screen in Collaborate Ultra, you may experience a tunnel view, or infinite-window effect. This will occur when you share the screen or browser that is displaying the active Collaborate session.

How to avoid the tunnel effect:

  • Do you have more than one monitor or screen? If so, share the screen that is not currently hosting your Collaborate session. 
  • Share an Application Window or an individual Chrome Tab rather than the entire screen.
  • Share a PowerPoint by uploading it into Collaborate and sharing the file.

The following video tutorial will walk you through avoiding the tunnel view in Blackboard Collaborate Ultra.
