2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
3) Click the Update button next to the video driver to automatically download the correct version of that driver, then you can manually install it.
Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version which comes with full support and a 30-day money-back guarantee. You’ll be prompted to upgrade when you click Update All.)

If you still have the problem, then try the next fix below.
Fix 4: Turn on/off Hardware Acceleration
When you run an application, it uses the standard CPU on your computer. If you run a heavy task, such as sharing your screen from Zoom, your app will use other hardware components on your PC to work more effectively.
If you have good hardware, enabling Hardware Acceleration will result in better performance of your application; however, if your hardware is weak, this feature may cause problems for you.
To see if this is the culprit for the black screen, try turning off/on Hardware Acceleration.
1) Open Zoom.
2) Go to Setting > Share screen > Advanced.
3) Uncheck Enable hardware acceleration to optimize video sharing.
Try screen sharing again with Zoom. If the black screen issue happens again, try the next fix.
Fix 5: Exit full-screen mode
If you’re running Zoom on the full-screen mode when the issue occurs, try exiting out of the full screen and then share your screen.
1) Open Zoom.
2) Go to Settings > General.
3) Uncheck Enter full screen automatically when starting or joining a meeting.
If the issue still exists, then move on to the next fix below.
Fix 6: Reinstall Zoom
If you still can’t get Zoom to work correctly, it could be an issue with Zoom installation files. In this case, uninstalling Zoom then reinstalling it could help.
1) On your keyboard, press the Windows logo key and R at the same time to open the Run command.
2) Type appwiz.cpl and click OK.
3) Right-click Zoom and click Uninstall.
4) Download and install Zoom.
