A system and method for improving stereoscopic images produced by a projecting device containing a single chip DMD, seen through an eye-switching device, such as a pair of liquid crystal (LC) shutter glasses. The system and method are used with a video projector designed to be used with a multiple-color, color switching device, such as a color wheel. The color wheel includes at least three critical color segments. The color wheel may also physically include or be electronically re-defined to include at least one non-critical segment. A color sequencing firmware resident in the video projector is used to align a non-critical segment in front of the projector's main light source during the eye-switching device's unstable transition phase. If the non-critical segment is transmissive, the firmware controls the DMD so that light is discontinued. If the non-critical segment is non-transmissive, the light is physically blocked. If the non-critical segment is electronically defined, the firmware directly controls the DMD to discontinue the transmission of light for at least the duration of the eye-switching device's unstable transition phase.
