In the Nearo desktop app, be in a session. Click the Share Screen button in the controls bar, the dark gray strip along the bottom of the call window. It is next to the camera button, right after it. In the small floating window, it is in the row of buttons under the video tiles. In a Room, it becomes available once a guest has joined.

A window opens showing your screens, with your open windows below them.

Click the screen you want to share, or click a window to share only that window. The window closes and sharing begins immediately.

If only one screen appears, you still need to click it to start sharing.

Click Share Screen in the controls bar, then scroll down in the window that opens to the Windows group, which sits below the Screens group.

Click the window you want to share. Sharing begins immediately.

The other person sees only that window. Your other apps and notifications do not show.

If you move or resize the window, what the other person sees follows it.

If you minimize the window, move it to another desktop or hide it, the other person sees the last picture with a message that your shared window is minimized, on another desktop or hidden. The picture comes back on its own when the window is back on your screen.

If you close the shared window, sharing stops and Nearo shows "The window you were sharing was closed, so sharing stopped".

The other person can still control the window, with extra limits that protect it. See Using remote control during a Nearo session.

Nothing is hidden until you choose an app. Nearo remembers your choices on that computer.

Click Share Screen in the controls bar. At the bottom of the window that opens, just above Share system audio, click Hide apps…. If apps are already hidden, that spot shows a bar that starts "Hidden from this share" with a blue Change button, so click Change instead.

In the Hide apps from this share panel, click each app you want to hide. A hidden app turns blue with a check mark. Only apps with a window open are listed, so open the app first.

Click Done, then click the screen you want to share.

On a Mac, hidden apps are left out of the shared picture. On Windows, hidden apps are covered by a gray box, and a window that is moved quickly can show for a moment. For full privacy on Windows, share one window instead.

Hiding apps does not apply when you share one window, because a window share never shows other apps.

The Share Screen button changes to a monitor with a line through it and reads Stop Sharing. In the small floating window, it also turns blue.

Your call shrinks into the small floating window so you can see what you are sharing. Nearo returns you to the full window when you stop.

The floating window shows a blue Sharing label with a Stop button. In the full window, a banner across the top reads "You are sharing your screen" with a Stop sharing button.

Amber markers appear in all four corners of the screen you are sharing, or on the corners of the window if you share one window. Only you see them; they are not part of what the other person sees.

Click Share Screen to open the list of screens you can share.

At the bottom of that window, the box next to Share system audio is already checked.

Uncheck Share system audio before clicking the screen you want to share if you do not want your audio shared.

In the Nearo desktop app, click the three dots at the right end of the controls bar, next to the red End Call button. Choose Cursor Names, then check Hide names on cursors. In the small floating window, the three dots at the right of the top row are called Options, and they hold the same choice.

In the web app, while you are watching a shared screen, click the three dots at the right end of the controls bar, next to the red End Call button, and choose Hide Names on Cursors. If the video tiles are at the left or right of the shared screen, the controls are in a panel under the tiles, and the three dots come just before End Call.

Click Share Screen to stop sharing.

Click Share Screen again to reopen the list of screens and windows.

Click the screen or window you want to share.

Click Share Screen again, click Stop sharing on the banner across the top of the full window, or click Stop on the blue Sharing label in the floating window.

Sharing also stops when the call ends.

Stopping the share also turns off remote control and drawing.

Guests who joined from the web cannot share their own screen.

Guests who joined from the Nearo desktop app can share their screen using the same steps above.
