description System and method for reducing failures due to hinge memory in a microdisplay display system. A preferred embodiment includes setting the state of each micromirror in a digital micromirror device based on an image being displayed, recording a usage history for the micromirrors, and providing a sequence of states to each micromirror when the display system is in an inactive mode. The sequence of states provided to a micromirror is based on the micromirror's usage history. The operation of the micromirrors while a display system containing the digital micromirror device is not in active use can help to reverse or eliminate hinge memory, thereby extending the lifetime of the digital micromirror device.
