Issues with black screen when using Zoom

[BMV1]

My screen screen will sometimes go black when in Zoom.  Everyone else in the meeting can still see and hear me, but I cannot see them and lose control of my screen.  The last time this question was asked in this forum (in June '20), the HP rep. incorrectly addressed the problem as though it were an issue with that persons camera but it's our screen not working in Zoom.  Apparently my camera is still working as others can see and hear me.  Please help.

@BMV1 The black screen during screen sharing could be caused by a graphics card with automatic-graphics switching (such as an Nvidia card).

1. Open the Nvidia Control Panel in the Windows Control Panel.
2. Click Manage 3D Settings.
3. Click on Program Settings under I would like to use the following 3D settings.
4. Under Select a program to customize, add Cpthost.exe from the Zoom bin directory.
5. Click Add.
6. Find Cpthost.exe from the Zoom bin directory (located at C:/>Users>YOURUSERNAME>AppData>Roaming>Zoom>bin).
7. Click Add Selected Program.
8. Under Preferred Graphics Processor, select Integrated graphics
9. Click Apply.
10. Try screen sharing again with Zoom.

If the issue persists, try another app or refer to Zoom support.
