The problem

Full-screen Webex shares can be hard to read

In Webex meetings, sharing a full ultrawide or high-resolution display can make the content difficult for viewers to read. Sometimes you only want to show a specific section of your screen, not your entire desktop or a full app window.

  • Full-screen sharing can make text and details too small
  • A single app window may not show the exact region you need
  • Switching between windows when sharing more than one app becomes a hassle
  • Changing display settings before a meeting is disruptive
  • Private or unrelated desktop content may be visible
  • Presentations and support calls work better with a focused view
The solution

Share a focused region in Webex instead

RegionMirror creates a separate Mac window that mirrors the selected region of your screen. In Webex, share the RegionMirror window to give viewers a focused, readable view.

How it works

Three steps to sharing part of your screen in Webex
