ERROR: Missing Images or Invalid Source Rect Error when Tobii Pro Lab display is not properly defined [30941]

This article applies to:

E-Prime Extensions for Tobii Pro 3.2

Detail

Users may not see images in Tobii Pro Lab if multiple monitors are used and the monitor used for Tobii Pro Lab is not defined.

In addition, users may get an "Invalid Source Rect" error if the Tobii Pro Lab monitor is not properly defined. This error is likely to occur when using two or more Display Devices set to different resolutions.

Like the TET PackageFile, the TobiiProLab PackageFile defaults to the first Display Device listed in the Experiment Object's Devices list. Similar to TET, a default monitor should be specified for Tobii Pro Lab-enabled experiments that have multiple displays.

Users can define the default Tobii Pro Lab monitor by calling the following script in an Inline object at the beginning of the Session Procedure:

'Replace "Display" with the name of the monitor that should be displayed in Tobii Pro Lab.

TobiiProLab_SetMonitorDefault "Display", True
