How to Share Screen on Zoom: Full 2026 Guide
To share screen on Zoom: click the green Share Screen button in the meeting toolbar, pick a monitor or an open window, tick Share sound if your content has audio, then click Share. Four clicks, five seconds.
The clicks are easy. Choosing between the nine or so things in that share window, and working out why nobody can hear your video, is what eats the first two minutes. Here's the rest, in the order you'll need it.
Share your screen on Zoom, step by step
- Open what you plan to show. Zoom only lists windows that are already running. Launch the deck or tab first and the picker will find it.
- Click Share Screen. The green button in the middle of the meeting toolbar. Alt+Shift+S on Windows, Command+Shift+S on Mac, both rebindable under Settings → Keyboard Shortcuts.
- Choose what to share. The Basic tab lists each monitor separately, every open window and the whiteboard. Advanced and Files sit alongside it.
- Check the bottom-left corner. Two checkboxes live down there: Share sound and Optimize for video clip. Both are off until you tick them.
- Click Share. A green border outlines what's live, the toolbar jumps to the top of your screen, and Stop Share sits at its right end.
Screen, Window, Portion, Whiteboard: what you're actually picking
Zoom splits the picker into three tabs and most people never leave the first. Basic holds monitors, open windows and the whiteboard. Advanced hides the useful stuff: Portion of Screen shares a resizable frame instead of a whole display, Computer Audio sends sound with no picture, Content from 2nd Camera pipes in a document camera, and Slides as Virtual Background puts your deck behind your face. Files pulls documents from Box, Drive, OneDrive or SharePoint.
| What you're doing | Pick this | Why |
|---|---|---|
| Walking through one app | Window (Basic) | Alerts and other apps stay private. |
| Jumping between several apps | Screen (Basic) | No gaps when you alt-tab. |
| One panel of a huge monitor | Portion of Screen (Advanced) | A readable crop, not a whole ultrawide. |
| A video or clip with sound | Window + Share sound + Optimize | Higher frame rate, audio arrives. |
| Sketching with the room | Whiteboard (Basic) | Everyone draws, board outlives the call. |
| Music with nothing on screen | Computer Audio (Advanced) | Sound only. Desktop stays yours. |
| A physical object or document | Content from 2nd Camera (Advanced) | A real camera feed, not a window. |
| Slides with your face on them | Slides as Virtual Background (Advanced) | You stay visible, not a corner tile. |
The checkbox that decides whether anyone hears anything
This is the most common Zoom share failure, and it isn't your fault: Zoom sends your microphone by default and your computer's own audio only on request. That's why a shared clip arrives silent, or as a tinny echo picked up by your mic.
The fix is the Share sound checkbox at the bottom-left of the share window. The arrow beside it offers Mono or Stereo (high fidelity) — stereo for music, mono on a weak connection. Forgot? The More menu on the share toolbar carries the same toggle mid-share.
Mac gotcha worth 30 seconds: the first time you share sound on macOS, Zoom asks to install a small audio driver. Dismiss that prompt and the checkbox still ticks and still sends nothing. Test with a two-second clip before the meeting starts.
Playing a video without turning it into a slideshow
Screen sharing is tuned for still content — slides, code, spreadsheets — so it favours sharpness over motion. Play a 30-frame-per-second video through it and viewers get a stuttery flipbook.
Optimize for video clip flips that: more frames, softer detail. Tick it only for actual footage and untick it after, or shared text stays permanently soft. Two things help more than the checkbox does: full-screen the video in its own window first, and share that window, not the desktop.
Sharing from a phone or an iPad
On iPhone and iPad, tap Share Content, choose Screen, then Start Broadcast. iOS asks for broadcast permission the first time and counts down from three. Return to Zoom and tap Stop Broadcasting to finish. Android is the same path with a Start Now confirmation.
Often the better move is not to broadcast at all: the same menu shares a photo, document, cloud file, whiteboard or web page directly. While broadcasting you can't see the gallery, so you're presenting blind. From the desktop app, the Basic tab's iPhone/iPad entry mirrors a device over AirPlay.
Annotation, and handing over the mouse
Once a share is live, the presenter gets Annotate on the share toolbar; viewers find it under View Options → Annotate. Hosts can disable participant annotation, or show the name of whoever is drawing, from the More menu — handy the moment someone doodles on your pricing slide.
Remote control is a bigger step. While sharing, click Remote Control and pick a person; from the other side it's View Options → Request Remote Control. That hands over real keyboard and mouse input, not a pointer. One person at a time, desktop app only, and your admin has to have enabled it in the web portal. Click your own screen to take it back.
Two people sharing at once
Zoom allows simultaneous shares. Click the arrow beside Share Screen, open Advanced Sharing Options, and set How many participants can share at the same time to multiple. The same panel sets who can share at all, and who can start one while someone else is presenting. Everyone needs the desktop client, and single-monitor viewers have to toggle between shares by hand.
When the Share Screen button isn't there
The cause is almost always one of these, in roughly that order of likelihood.
- Sharing is host-only. Ask the host to open Security and tick Allow participants to Share Screen. Being made co-host also restores it instantly.
- An admin locked it. On a managed account the screen sharing toggle in the Zoom web portal can be locked at group or account level, and nothing in the meeting overrides it.
- Your own setting. Disable desktop/screen share for meetings you host removes the advanced options from your in-meeting menu.
- macOS permission. System Settings → Privacy & Security → Screen & System Audio Recording, enable Zoom, restart the app. Usual cause of a black share on a Mac.
- You joined from a browser. The web client shares in Chromium-based browsers, but the Advanced tab and remote control are desktop-app features.
Sharing one window without showing the rest of your life
Everyone has seen a Slack DM land in the middle of a client demo. A few habits prevent it.
Pre-share checklist: share a window, not a screen, whenever you can. Turn on Silence system notifications when sharing desktop under Zoom Settings → Share Screen, and add macOS Focus or Windows Do Not Disturb on top, because a few stubborn apps push through anyway.
Close spare tabs before you share, not after — your bookmarks bar is visible too. And Pause Share (Alt+T, or Command+Shift+T on Mac) freezes the picture while you go hunting for a file.
One thing worth being clear about: sharing isn't recording. Nothing is saved when a share ends. For the file, that's the record button in the same toolbar — see recording a Zoom meeting, or, for a local macOS capture, screen record on Mac with audio. Doing the same demo in Microsoft Teams? Here's how to share your screen on Teams.
The other thing that ends with the share is everyone's memory of what was decided. That's the gap an AI meeting assistant that writes up the call fills, without anyone typing while you present.

The bottom line
Almost every awkward Zoom share traces back to two habits: sharing a whole screen when a window would do, and forgetting that computer audio is opt-in. Fix those and you've fixed the ninety seconds of apologising that opens too many calls. The rest is there when you need it.
Frequently asked questions
How do I share my screen on Zoom?
Click the green Share Screen button in the meeting toolbar, choose a monitor or an open window, then click Share. Tick Share sound in the bottom-left corner first if the content has audio, and tick Optimize for video clip if you are playing a video. A green border marks what is live, and Stop Share ends it.
Why can nobody hear the audio when I share my screen on Zoom?
Zoom sends your microphone by default and your computer sound only if you ask for it. Tick Share sound in the bottom-left of the share window before you click Share, or switch it on from the More menu on the share toolbar mid-share. On a Mac, Zoom installs a small audio driver the first time, so approve that prompt.
What is the difference between sharing a screen and sharing a window on Zoom?
Sharing a screen shows everything on that monitor, including notifications, other apps and anything you open next. Sharing a window shows only that one application, and viewers see a blank or frozen area if you move something else over it. Window sharing is the safer default. Portion of Screen, on the Advanced tab, shares a resizable rectangle instead.
Can two people share their screen at the same time on Zoom?
Yes, if the host turns it on. Click the arrow beside Share Screen, open Advanced Sharing Options, and set how many participants can share at the same time to multiple. Everyone needs the desktop app, and a second monitor helps, because viewers on one screen have to switch between the two shares manually.
How do I share my screen on Zoom from an iPhone or iPad?
Tap Share Content in the meeting controls, choose Screen, then tap Start Broadcast and wait for the three-second countdown. iOS asks for broadcast permission the first time. Return to Zoom and tap Stop Broadcasting when you are done. If you only need one file or photo, share that directly from the same menu instead.
Why is the Share Screen button greyed out on Zoom?
Usually the host has limited sharing to hosts only. Ask them to open Security and tick Allow participants to Share Screen. On managed work accounts, an admin can lock screen sharing off in the Zoom web portal, and no in-meeting setting will override that. On macOS, a missing Screen and System Audio Recording permission produces the same result.
