One problem with the use of computer graphics monitors in vision experiments is spatial inhomogeneity: phosphor output intensity can vary between screen locations. This feature complicates accurate display of stimuli—either output must be confined to a small portion of the screen or variability must be accepted. We have developed a platform-independent spatial compensation algorithm to correct for variance in output luminances over the surface of the screen. We have implemented and tested this algorithm on our own graphics system. © 1993 John Wiley & Sons, Inc.
