How to Share an Ultrawide Screen in Microsoft Teams
Sharing a full 21:9 or 32:9 desktop in Teams leaves viewers squinting at compressed content. ZoneShare mirrors a clean, focused portion of your ultrawide display — and keeps the rest private.
Ultrawide Screens Don't Fit Teams the Way You'd Hope
The same monitor that powers your workday can derail a meeting.
Microsoft Teams scales shared content to fit the viewer's window. A 21:9 or 32:9 desktop becomes a thin strip across the screen, with your actual work compressed into a hard-to-read band.
Sharing a single app helps, but on an ultrawide display even one window is often much wider than a standard 16:9 frame. And switching between apps during a call means ending one share and starting another, which breaks the flow.
- Content scaled down. Viewers see a shrunken, letterboxed version of your desktop instead of the content that matters.
- App switching is clunky. Ending one share to show another app makes presentations feel disjointed.
- Private stuff on display. Chat windows, personal tabs, and notifications are visible to everyone.
- Distracted audience. Viewers try to decode tiny windows instead of listening to what you're saying.
Share a Clean, Focused Area Instead
ZoneShare turns any part of your ultrawide display into a neat, shareable region.
With ZoneShare you place a frame over the part of your screen you want to present — a slide deck, an editor, a spreadsheet — and that region is mirrored into a Zone Share window. In Teams you simply share that window.
Prefer to look like a webcam? Switch to the Zone Share Camera virtual camera and select it in Teams' camera menu. Your desktop stays clean, and the region always matches the ratio you picked. The same approach works in Zoom and Google Meet.
- Focused sharing. Present exactly the window or area you need — nothing more, nothing less.
- Clean 16:9 output. Standard ratios keep your share looking right in every viewer's window.
- Easy switching. Jump between saved regions with hotkeys, so moving from code to slides takes a second.
- Privacy by design. Everything outside your region stays off the call.
