The level of detail available in an image is determined by the number of pixels which make up the displayed image. In a DLP system, this is a function of the number of mirrors on the DMD which can represent one or more pixels on the display. Resolution is the number of pixels that can be displayed. The level of detail displayed is not only dependent on the projector system but it is also dependent on the resolution of the source content. If the source content does not match the resolution of the projector system, then the source content is mapped by the controller to make maximum usage of the resolution displayed.
