Sometimes when the presenter is sharing the entire screen on a Windows computer, the participants can only see a part of the screen. The issue is caused by the high DPI of the computer. The presenter can refer to the steps below to resolve the issue.
Step 1. Right click on your desktop, go to Display Settings and check the resolution.
Step 2. If the resolution is 1920*1080 or higher, please stop sharing your screen, go to Display Settings again and change the Text Size of the Scale and Layout to 100% or 125%:
3. Then you can share your screen again and see if that works.
