  • Using the Win + I shortcut keys, go to Windows Settings.
  • Select Privacy and scroll to find the Camera setting under “App permissions.”
  • Make sure “Allow access to this device’s camera” and “Allow apps to access your camera” are both switched on.

  • After you’ve finished, go to the official Zoom download website to acquire a new copy of the app.
  • The Screen Sharing feature should work properly after you install Zoom.

6.  Connect To Stable Internet Connection

Zoom requires a solid internet connection with moderate speeds for screen sharing. As a result, if you’ve observed slight lags or crashes in your video conferencing, it could be due to a bad Internet connection.

For the best video conferencing experience, you’ll need download/upload rates of 800kbps to 1mbps. You’ll need roughly 150kbps for screen sharing. I recommend verifying your internet speeds, which you can do with Speedtest OR Fast

  • Ping timings are also measured by Speedtest.net, which reflects the stability of your internet connection.
  • To avoid network connectivity troubles and this screen sharing error, ping times of roughly 50ms to 100ms are ideal.

You’ve noticed that your internet rates are prolonged. In that scenario, we propose doing the following simple measures to improve your internet:

  • Turn off your WiFi router, wait a minute, and then turn it back on.
  • This will delete the cache in your router and allow it to cool down.
  • Bring your WiFi router closer to you.
  • This step can help you avoid packet loss and enhance the stability of your internet connection.
  • Turn on Airplane Mode from your phone’s status bar (Android) or Control Centre (IOS), wait 1 minute, then turn it off for Mobile Internet users.
  • You’ll be able to connect to a better cell tower, which will improve your phone reception.

7. Participant Screen Sharing For The Zoom Room

The host has disabled “screen sharing by participants” for that meeting. You may not be able to screen share. This option is typically deactivated, allowing just the host to share their screen. As a result, the host may have neglected this setting for “All Participants.”

  • To share a screen, press the Share Screen button.
  • If you obtain the message “Host disabled participant screen sharing,” this feature is turned off for all participants.
Host disabled participant screen sharing
  • In that instance, send a message to the host via the Chat function to remind or inform them to “On” the setting.
  • If you’re the host and people are complaining about not being able to screen share, you can enable it under the screen sharing settings:

Windows and Mac OS

  • To begin, pick “Advanced Sharing Options” from the arrow next to the Share Screen button.
  • Then, under “Who can Share?” check the box for All Participants.

iPad and Android Devices

  • To begin, go to the bottom right and select More.
  • On the Meeting Settings page, turn on Share Screen under “Allow Participants to.”

8. Exit And Reenter The Zoom Call

For a better effect, I recommend restarting the Zoom application as well. With the Zoom app, you’re starting a new session. This clears any temporary cache that might have gotten in the way of your screen share.

  • Click the End button to end the meeting.
End button
select Exit
  • For Mac: Click the Zoom icon in the top Menu Bar, then pick Quit Zoom from the drop-down menu.
  • For iOS and Android: Tap the home button to exit the Zoom app, then delete it from your Recent Apps list.
  • Finally, return to the conference room by reopening the Zoom application.

9. Enable The Share Computer Sound option

This is a must-do stop if you’re screen sharing on Zoom and the audio isn’t working. To eliminate interruptions from your computer, this setting is usually turned off.

  • Click the Share Screen icon in the bottom left, look for the “Share Computer Sound” setting.
  • To enable it, make sure the box next to it is checked.
"Share Computer Sound"
  • I recommend enabling the Optimize Screen Sharing for Video Clip setting, which is immediately next to it.
  • This option is usually disabled by default, although it can prevent Zoom screen sharing issues.

10. Stop Your Video Before Choosing To Share Screen

Zoom’s screen sharing is highly reliant on your internet connectivity. Furthermore, when using solely audio calling, video conferencing consumes much more bandwidth.

  • Before attempting to screen share, I recommend turning off your video. Simply select Share Screen from the bottom bar after selecting the Stop Video button.
  • Furthermore, if you entered the Zoom room with the video already turned on, the Zoom share screen option may not function.
  • By selecting End, you can exit the room. Then, when entering the Meeting ID, pick Turn off my video to return to the Zoom room.
  • Only your audio is streamed when this option is selected. Instead of streaming your video, you can use less bandwidth.

11. Allow All The Necessary Permissions For The Zoom App

Another reason the Zoom share screen feature isn’t working is that the app lacks the appropriate rights to access specific resources. Screen sharing on Zoom, of course, is a tool that relies on a variety of resources, primarily video, screen recording, and audio.

Check to see if activating all permissions fixes the Zoom screen sharing issue.


  • Search for and launch Privacy Settings from the Start Menu. Then, on the left pane, go to App permissions and make sure Zoom Meetings is listed under “Allow Desktop Apps.”
Allow All The Necessary Permissions For The Zoom App
  • Carry out the same processes for the other permits. I recommend checking the Camera and Microphone for Zoom.

Mac OS

  • Select System Preferences from the Apple Menu (click the Apple logo in the upper left). After that, go to Security & Privacy.
  • Select Screen Recording from the left menu and click the lock symbol in the bottom right corner to make adjustments.
  • You may need to enter your admin password. Finally, select Zoom from the drop-down menu.
  • IOS: Open the Settings app on your iOS device, scroll down, and pick Zoom. Make sure Zoom has all of its permissions turned on.


  • Open the Settings app, choose Apps & notifications, and then select Zoom from the list of apps.
  • Select Permissions and tap on permission under Denied.
  • Allow or Allow just when using the app is the option to select.
  • Finally, repeat this process to allow all of the other permissions.

12. Disable Switch Between GPUs

Enabling this setting is one of the most common causes of a black screen on your Zoom share for laptops with a dedicated GPU, such as an NVIDIA graphics card.

Mac OS

  • Select System Preferences from the Apple Menu (click the Apple logo in the upper left corner).
  • Next, go to Energy Saver and uncheck the box following Automatic graphics switching on the next screen.
  • Now, Check if the “zoom screen sharing not working” issue is fixed or not.
