During a call or meeting, click Share content .

Select the Advanced tab.

Choose one of the options from the optimization drop-down list:

• Automatically optimize—Chooses the best optimization for your content type.
• Optimize for text and images—Displays text and images in your shared content at the highest resolution and clarity possible.
• Optimize for motion and video—The video plays back in a lower resolution to reduce lag and increase fluidity in your shared video, animation, or dynamic content.

  This option may not improve the frame rate in meetings with over 25 attendees. If you choose this option, Share computer audio is automatically turned on for you.

  Mac only: Webex App needs an extension to share your computer audio. If you don't have the extension, then Webex App downloads it when you click Optimize for motion and video or Share computer audio. You must have administrator permission on your computer to install the extension and share audio.

When you share content with audio, select the Share computer audio check box to allow others to hear your computer audio in addition to your microphone audio.

Select Portion of screen, and then click Next.

Move the frame to the portion of the screen that you want to share. If you have multiple screens, move it to the screen that you want to share.

Drag the resize handle on any of the four corners or sides to make the frame larger or smaller. The portion that the frame covers is the portion that you'll share in the meeting.

Click Share.
