What happens if people in a meeting have different sized monitors or resolutions?

In a WebEx meeting, all of the attendees can automatically view all of the meeting content, even if they have different display resolutions. No matter what resolution the attendees have, the audience's view will follow the mouse pointer automatically. So, the presenter should always have the mouse pointer near what they are talking about. Setting the host's monitor to 800 x 600 pixels usually produces the best results, since this is the most common resolution. You can change the display resolution setting for Windows in the Settings tab in the Display Control Panel, and for Mac OS, in the Monitors Control Panel.
