A projector stacking stand for supporting at least one image projector comprises a frame and at least one mounting platform connected to the frame with ends supporting an image projector. Each mounting platform is connected to the frame for enabling adjustment of the pitch, roll and yaw thereof relative to the frame by means of a gimbal having three discrete pivot axes corresponding to pitch, roll and yaw axes. The gimbal is moved about the pitch and roll axes by two shafts, each mounted on the gimbal for independent rotation with the axis thereof disposed parallel to the pitch axis and a cable for each shaft having at least one turn therearound. Each cable is connected to the frame under tension with a portion above and below the turn around the shaft and each shaft is rotatable to effect vertical movement thereof along its cable, whereby pitch adjustment is obtained by rotating the two shafts simultaneously in the same direction and roll adjustment is obtained by rotating the shafts individually. The platform is rotatable about the yaw axis relative to the gimbal for yaw adjustment.
