Showing everyone the same thing, live
Instead of emailing a file and hoping everyone opens it, screen sharing puts exactly what you're looking at in front of every participant in real time, which keeps a presentation or a walkthrough moving without back-and-forth.
Picking the right sharing mode for the moment
Sharing a single tab keeps other windows, notifications, and messages private, which is the safer default for most presentations. Sharing your entire screen only makes sense when you need to switch between several apps live -- just remember to close anything sensitive first.
Frequently Asked Questions
Can I share audio too, like a video or music?
Yes -- when you choose to share a tab, turn on the "Share tab audio" checkbox that appears, and sound playing in that tab will be sent to participants along with the video.
Will others know I'm sharing my screen?
Yes, once sharing starts, an icon appears in the meeting view and in the participant list to indicate that your screen is currently being shared.
