Screen sharing for macOS

Presenting on an Ultrawide Monitor Without Sharing Your Entire Screen

Designers, developers, and presenters love ultrawide displays — until it's time to share. ZoneShare creates a focused presentation area on your 21:9 or 32:9 monitor while keeping the rest of your desktop private.

The Problem

The Wide Screen Presenter's Dilemma

Your monitor shows everything. Your presentation shouldn't.

Ultrawide monitors are built for multitasking: code on one side, browser on the other, notes in between. But when you present, all of that context becomes noise. Viewers don't want to watch you hunt for a window across 32 inches of desktop.

The bigger the monitor, the more visible your working desktop — and the harder it is to keep a presentation clean, focused, and professional.

  • Too much on screen. A busy desktop dilutes your message and makes presentations feel unfocused.
  • Scaling problems. A full 21:9 or 32:9 share shrinks your content to fit a 16:9 viewer.
  • Privacy exposure. Design files, code, messages, and notes are visible to everyone.
  • Awkward transitions. Moving between apps on a wide desktop is a slow, visible process for the audience.
The Solution

Create a Focused Presentation Area

ZoneShare turns part of your ultrawide screen into a clean presentation stage.

  • Frame your stage. Place a 16:9 or custom frame over the content you want to present.
  • Keep the rest private. Everything outside the frame stays off-screen — notes, code, messages, and all.
  • Present with tools. Add spotlights, drawings, zoom, and a timer directly inside the shared area.

With ZoneShare, your presentation area is whatever rectangle you choose — a Keynote window, a Figma artboard, a browser tab, a document. That region is mirrored into the Zone Share window or the Zone Share Camera, and the rest of your ultrawide desktop never appears.

Because the region is a standard ratio, it renders large and sharp for every viewer. Combined with drawing and annotation, it's a complete presentation workflow. If you often present standard-ratio content, our guide to sharing a 16:9 area is a good next read.

FAQ

Ultrawide Presentation Questions

Quick answers about presenting from an ultrawide monitor

Can I present from an ultrawide monitor without sharing my whole screen?

Yes. ZoneShare lets you frame the exact area you want to present — slides, a design, a document — and shares only that region. The rest of your desktop stays private.

Does ZoneShare work with Keynote and PowerPoint?

Yes. Keynote and PowerPoint are normal macOS windows, so you simply frame the window and share the Zone Share window or Zone Share Camera.

Can I annotate or draw during my presentation?

Yes. ZoneShare includes a drawing toolbar, spotlight, and zoom tools that work directly on the shared region.

Can I switch between presentation areas during a call?

Yes. You can move the frame at any time, and Pro users can set up hotkeys to jump between saved regions instantly.

Will my notes and other windows be visible?

No. Only the region you select is mirrored. Speaker notes, code, and other windows outside the frame are never shared.

Is ZoneShare free?

ZoneShare is free to download from the App Store and lets you mirror a portion of your screen. Pro adds custom frame size, blur, hotkeys, and more.
