A greater than ¼ lambda waveplate is inserted in a light channel between a microdisplay and optics directing the light channel. The waveplate is rotated such that a main component of the retardation of the waveplate is along a skew ray axis of light from the optics, and a minor component of the retardation of the waveplate is perpendicular to a residual retardation axis of the microdisplay. The main component has a magnitude of ¼ lambda, and the minor component has a magnitude equivalent to a magnitude of residual retardation of the microdisplay.
