A method and system is provided to extend operational life of a mirror array of an image generating system, wherein the image generating system further includes a high intensity power light source to cause light to impinge on the mirror array, sufficient to cause deleterious plastic deformation of associated hinges of the mirror array, and an image output generating section configured to receive light from the mirror array. Image date is received by the image generating system image data to control mirrors of the mirror array and to generate an output image. A required level of illumination is provided from the mirror array to the image output generating section over a predetermined time period, in accordance with the received image data. Then during at least a portion of the same predetermined time period of providing the required level of illumination from the mirror array to the image output generating section, de-stress switching operations are performed for selected ones of the mirrors of the mirror array to reduce the plastic deformation of the associated hinges. Next, an output image is generated based on the received image data, wherein the de-stress switching operations occurring during at least a portion of the providing of the desired level of illumination is undetected.
