The display settings control some aspects of the main page of the eyevec-control application. None of the display settings affect the actual eye-tracking.

These settings can be written to a settings file .eyevec-displayrc (in your home directory) using the eyevec-control application. This makes the display settings persistent across eye-tracking sessions. You can edit the settings file using any plain text editor.

Details

The names of all settings are in lowercase with dashes between the parts that make up the name. In the settings file however the dashes are removed. For instance the setting named show-pupil-center is called showpupilcenter in the settings file.
