In some cases a black screen can be observed over top of the game screen, or when toggling to the game in single-monitor mode. This is observed most commonly after a session has already been run on the system.
To resolve the issue exit the session and close out of EEGer. Even if the screen is appearing black, it may be possible to press esc to exit the session or spacebar to toggle back to the wave screen. Reopen EEGer once closed and attempt to run a session again, observing if the issue is resolved.
It is possible that the above steps can not be followed and the black screen persists. We will use the computer’s Task Manager to tell Windows to force the black screen to close:
If this issue occurs commonly, we suggest upgrading to the latest version of EEGer. This may help resolve the issue, or will make troubleshooting the issue easier when contacting support.
