What the independent test changes
If DeviceOK passes
DeviceOK screen capture working proves OS/browser capture is possible; OBS can still have source or permission issues of its own.
If DeviceOK fails
If DeviceOK capture is blocked too, resolve OS/browser capture permission first.
Check these in order
- 1
Run DeviceOK Screen Share Test as a basic OS/browser capture-permission check.
- 2
Confirm the intended display/window source exists in OBS.
- 3
Verify operating-system screen-recording permission where required.
- 4
Restart OBS after permission changes when the OS requires a restart of the app.
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.
