Microsoft Teams continues its Formula 1 race in the world of video conferencing apps. The company came ahead with Microsoft Teams with its new features and functionality. Among these, screen sharing is probably the most important feature, useful for showing content to other participants. If you are having trouble sharing your screen on Microsoft Teams, please read below to find out how to fix it.


Screen sharing is useful for administrators and educators who show their display configuration to other members during the call. You can also use the built-in whiteboard in Microsoft Teams to collect ideas and thoughts.



When screen sharing not working in Microsoft Teams on Windows 10, it could force you to find alternatives and reduce the productivity of your team. Thankfully, it's easy to fix screen sharing not working on Microsoft Teams. Read below to find out how.

1. USE A HIGH SPEED INTERNET CONNECTION

You are practically sharing your PC display with other members while video calling in screen sharing mode. This may sound simple in theory, but it requires high-speed internet speeds for flawless background results.


You can visit fast.com or use services like Speetest and make sure you have good internet speed numbers. If your Windows 10 PC or laptop is connected to the 2,4GHz Wi-Fi network, consider switching to 5,0GHz for a better connection and speed.

2. CLOSE / PAUSE IRRELEVANT APPS THAT CONSUME DATA

If a third-party app or web browser tab is downloading or streaming large files over the internet, you should consider stopping the download process while screen sharing in Microsoft Teams.



Make sure Microsoft Teams gets the maximum bandwidth to use during long video calls and you won't face any problems.


3. CLOSE BACKGROUND APP AND ACTIVITIES

This applies to PCs and laptops with low RAM numbers. When you have too many apps and task processes running in the background, it interferes with Microsoft Teams and its features, such as screen sharing.

Follow the steps below to close background apps and tasks.

Step 1: press the Windows key and type Task Manager.


Step 2: hit Enter and open the app.

Step 3: If you notice unnecessary CPU usage by a random app or process, click on it and hit End Task at the bottom.

If you often run into problems with Microsoft Teams, you should make it a routine and stick with it before an important meeting.

4. USES GOOGLE CHROME OR MICROSOFT EDGE

If you are using the web version of Microsoft Teams, you must use Google Chrome or Microsoft Edge on Windows 10.

Instead of using Firefox or Vivaldi, consider switching to Chrome or Edge for a seamless screen sharing experience in Microsoft Teams.

5. MAKE SURE YOU HAVE SCREEN SHARING AUTHORIZATION
