Screen sharing is a feature of video-call and collaboration tools that sends a live view of your display, one window or one browser tab to other participants. Zoom, Teams, Google Meet and Slack Huddles all provide it. Unlike remote desktop, viewers normally watch only, unless you grant control.
Why it matters
It is the main way to present slides, demonstrate software, review documents and troubleshoot with colleagues remotely. The shared stream is often compressed to cope with limited bandwidth, so text can look blurry on a poor connection. Privacy is the main risk: anything visible on your screen, such as notifications, tabs or credentials, can be seen by everyone.
Example
Before a call, a presenter closes the email client, turns on Do Not Disturb and chooses to share a single window instead of the whole desktop. Mid-call, a participant asks to point at something, and the presenter allows "Request control" for that person. Many tools also share computer audio, which must be switched on separately to play a video with sound.
Common mistakes
- Sharing the entire screen when one window would do.
- Leaving notifications, password managers or private tabs visible.
- Forgetting to stop sharing at the end of the meeting.
