Fix 3 – Check Internet Connectivity

What we mean by checking your internet connection is to ensure you are using a stable internet connection. This is important because Zoom cannot work on a connection with a speed less than 800kbps and for screen sharing, you need 150kbps minimum. In case your internet speed is not even this much or the connection drops, you need to boost your internet connection speed. 

To boost speed, switch off your Wi-Fi connection for a minute and then turn it on. Also, we suggest moving the Wi-Fi router closer. Both these steps will help boost speed and will also prevent packet loss thereby enhancing internet connection stability. 

Mobile users can enable Airplane for a minute and disable it later to see if this helps. 

Fix 4 – Turn off the video before sharing the screen

As explained above Zoom depends on internet bandwidth. Moreover, video conferencing consumes more bandwidth hence if the Zoom share screen is not working try stopping the video and then try to share the screen. This should work.

Fix 5 – Enable all necessary permissions

If the Zoom app doesn’t have the necessary permissions you might face Zoom screen sharing not working issues. Hence, to avoid facing the Zoom screen share problem and to take share screen control you need to enable all permissions.

Windows users need to type Privacy Settings in the Windows search bar. Next, they need to click App permissions > select permission > and make sure Zoom Meetings is enabled under Allow Desktop Apps. 

Repeat the same steps for other Zoom settings. 

Mac users need to click the Apple icon > System Preferences > Security & Privacy > Privacy > Screen Recording > click the lock icon > enter admin password > check the box next to Zoom.

Android users need to head to Settings > Apps & notifications > select Zoom > Permission > under Denied tap permission > here either select Allow or Allow only while using the app. 

Repeat the steps for all the other permissions.

iOS users Settings > Zoom > toggle on all the permissions 

That’s it, now try sharing the screen when using Zoom on either of the devices, you should not face any problem. 

Fix 6 – Turn off automatic switching between GPUs

Generally, to extend battery life this feature is disabled but if it is enabled Zoom screen sharing problem occurs and you also see the black screen. To fix this, we need to disable automatic switching between GPUs.

To do so, here’s how to turn off switching between GPUs
