Software-generated calibration images may be presented on a display having two optics. One or more settings for presentation of the calibration image are adjusted. The settings are related to an inter-pupillary distance (IPD) of the user. An input is received from a user when the user perceives the calibration image to be acceptable at a particular value of the one or more settings. An IPD value that corresponds to the particular value of the one or more settings is then determined. The determined IPD value is used in presenting subsequent software-generated images with the stereoscopic display. ## Claims ### Claim 1 A method, comprising: presenting a calibration image on a display device having two fixed optics configured for a specific inter-pupillary distance;
