EEGer4 can be configured for use in a variety of display configurations. 


In single monitor mode, the user can begin a session and toggle between the therapist screen and the game screen by pressing the space bar on the keyboard. Single monitor mode does not allow for adjustments to be made to the session while the game screen is displayed. To make changes, the user must first switch to the therapist screen by pressing the space bar.

Dual monitor mode allows for the therapist screen to be displayed on one monitor and for the game screen to be displayed on a second monitor. This is the most common screen configuration, as it allows for changes to be made during the session without interupting the feedback. Dual display mode does this by removing the need to toggle between screens with the space bar.


For EEGer to display properly, Windows must be set to Extend displays. This can be done in the Settings App or can be quickly changed by pressing Win+P on your keyboard. This will display a Project menu on the right side of the screen. Here the user can select Extend to change WIndows to the appropriate mode for use with EEGer. Once Windows is configured properly, open EEGer. To use dual display mode, first ensure that an external display is connected to the computer. Commonly, users will connect their computer to a widescreen monitor, portable USB monitor, or via HDMI to a television. Once an external or secondary display is connected to the computer, we must change Windows display mode. 

From the top toolbar of EEGer's main screen, navigate to Options>EEGer Configuration Options. In the menu that appears, change 1 System Display Mode to Dual monitor. After you close the preferences window, EEGer will restart automatically and open itself in dual monitor mode. If you encounter problems, please be sure that the secondary monitor is fully connected to the computer and is powered on.
