What the independent test changes
A successful DeviceOK screen-capture selection proves browser-level capture permission, not Zoom's own capture permission or meeting policy.
If the browser cannot open screen capture either, resolve browser/OS capture permission before focusing on Zoom.
Check these in order
- 1
Run DeviceOK Screen Share Test and confirm the browser can open a screen/window chooser.
- 2
If browser capture works, check Zoom's screen-share permission and the meeting host's restrictions.
- 3
On operating systems that gate screen recording, verify Zoom is allowed to capture the screen.
- 4
Restart Zoom after changing OS-level capture permission if the platform requires it.
Retest instead of guessing
After changing one setting, run the independent DeviceOK test again before moving to a more invasive step. This preserves evidence and avoids changing multiple variables at once.
