HP Display LiteSaver

HP Display LiteSaver is a software application, available on the CD, that increases monitor life and

saves energy. It allows you to place the monitor into its low power sleep mode at predefined times by

shutting down or reducing power to most internal circuits. This helps protect the LCD panel against

image retention. Image retention can occur when the monitor is left on while displaying the same

image for an extended period of time, leaving a shadow of the image on the screen.
