Share Specific Screen Areas in Zoom, Teams, and Google Meet

Stop sharing your entire desktop in video calls. Conjuly lets you select exactly which parts of your screen your audience sees — protecting your privacy, keeping the focus on what matters, and making your presentations look professional.

The Problem with Full-Screen Sharing

Every video call platform offers screen sharing, but the options are limited: share your entire screen, or share a single application window. Both approaches have significant drawbacks.

Full-screen sharing exposes everything on your display. Notification banners pop up mid-presentation. Private messages appear in the corner. Browser tabs with unrelated content are visible to everyone. On ultrawide monitors, the problem is even worse — your audience sees a compressed, nearly unreadable image squeezed into their standard-sized video frame.

Single-window sharing is better for privacy, but it is inflexible. You can only show one application at a time, and switching between apps means repeatedly stopping and restarting the screen share. If you need to show content from two applications side by side — a code editor and a browser, for example — single-window sharing cannot do it.

Conjuly solves both problems. Draw capture regions around the exact areas you want to share, and your audience sees only those areas — clean, focused, and at a readable size.

Two Approaches: Mirror Window vs. Virtual Camera

Conjuly gives you two methods for sharing screen regions in video calls. Choose the one that best fits your workflow and your platform.

Mirror Window Sharing

The mirror window approach uses your platform's native window sharing. Draw a capture region around the area you want to share. Conjuly creates a clean mirror window that displays only that content. In your video call, use the "Share Window" option and select the Conjuly mirror window. Your audience sees the content of your capture region, nothing else.

This approach works with every video call platform and requires no special configuration. It is the simplest way to share a specific screen area and is available in Conjuly's free tier.

Virtual Camera Sharing

The virtual camera approach embeds your screen regions directly into your camera feed. Select "Conjuly Camera" from the camera picker in your video call app, and your audience sees your screen content as if it were your webcam output. With Grid Mirror, you can compose multiple regions — and your webcam overlay — into a single, polished feed.

The virtual camera is ideal when you want to show screen content and your face simultaneously without toggling between screen share and camera modes. It also works in environments where screen sharing is restricted by IT policies, since it operates through the standard camera input.

Step-by-Step: Sharing Screen Regions in Zoom

  1. Open Conjuly and create a capture region around the area you want to share. The mirror window will appear automatically.
  2. In Zoom, click the Share Screen button in the meeting toolbar.
  3. In the sharing picker, switch to the Window tab.
  4. Select the Conjuly mirror window from the list of available windows.
  5. Click Share. Your audience now sees only the content inside your capture region.
  6. To adjust what you are sharing, move or resize the capture region on your screen. The mirror window — and therefore the shared content — updates in real time.

For the virtual camera approach in Zoom: go to Settings > Video and select "Conjuly Camera" as your camera source. Your screen regions will appear as your video feed. You can also switch cameras mid-call from the arrow next to the camera button.

Step-by-Step: Sharing Screen Regions in Microsoft Teams

  1. Create your capture region in Conjuly. Position the mirror window where it is convenient on your display.
  2. In Teams, click the Share button (the upward arrow icon) in the meeting controls.
  3. Under the Window section, find and select the Conjuly mirror window.
  4. Teams will begin sharing the mirror window. Your audience sees only the content of your capture region.
  5. Resize or reposition the capture region at any time to change what is being shared.

For the virtual camera approach in Teams: go to Settings > Devices > Camera and select "Conjuly Camera." Your Grid Mirror composite or single-region output will appear as your camera feed, allowing you to share screen content without using the screen share feature.

Step-by-Step: Sharing Screen Regions in Google Meet

  1. Set up your capture region and mirror window in Conjuly.
  2. In Google Meet, click the Present now button at the bottom of the meeting.
  3. Select A window from the sharing options.
  4. Choose the Conjuly mirror window from the window picker.
  5. Click Share. Your region content is now visible to all meeting participants.

For the virtual camera approach in Google Meet: click the three-dot menu, go to Settings > Video, and select "Conjuly Camera." This is particularly useful in Google Meet since it allows you to show screen content and your face in one feed, avoiding the layout shift that happens when toggling between camera and screen share.

Tips for Ultrawide Monitors in Video Calls

If you use a 34-inch or 49-inch ultrawide monitor, sharing your full screen in a video call results in a tiny, compressed image that your audience cannot read. Conjuly is built to solve this problem.

  • Capture only what matters. Draw regions around the specific areas your audience needs to see. A code editor, a terminal, a browser tab — whatever is relevant to the discussion.
  • Use Grid Mirror for multi-area sharing. If you need to show two areas from your ultrawide display, use Grid Mirror to compose them into a 16:9 window. Your audience gets a clean, readable layout instead of a stretched panoramic view.
  • Use size presets. Set your capture region to 1920x1080 (1080p) to ensure the shared output matches standard video dimensions. This prevents scaling artifacts and keeps text sharp.
  • Use the virtual camera for maximum flexibility. The virtual camera approach lets you compose regions, add your webcam overlay, and deliver everything as a single camera feed — perfect for presentations on ultrawide setups.

Privacy Features for Video Calls

Sharing your screen in a video call always carries privacy risks. Conjuly includes several features designed to protect sensitive information during calls.

  • Region-based sharing. The most effective privacy feature is also the most fundamental: share only the screen areas you choose. Everything outside your capture regions is invisible to your audience.
  • Real-time blur. Apply blur to sensitive areas within a capture region. If your IDE shows environment variables or your browser has a password manager visible, blur those areas while keeping the rest of the region sharp and visible. (Pro feature.)
  • Blocked Apps. Automatically hide specific applications from your capture regions. If Slack, Messages, or your email client overlaps with a capture region, Blocked Apps will prevent that content from appearing in the mirror window. (Pro feature.)
  • No cloud processing. All capture and compositing happens locally on your Mac. Nothing is uploaded to Conjuly's servers, and no data leaves your machine beyond what you intentionally share through your video call.
