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 your 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.
Installing the HP Display LiteSaver Software
1. Insert the CD in the computer CD-ROM Drive. The CD menu
displays.
2. Select “Install HP Display LiteSaver Software.”
3. After installing the software, click the HP Display LiteSaver
icon in the Windows system tray or right-click the icon and
select Configure... from the pop-up menu.
