Using Power Management
The LCD monitor follows the VESA approved DPM Power Management function.
The power management function is an energy saving function that automatically reduces the power consumption of the
display when the keyboard or the mouse has not been used for a fixed period.
The power management feature on your new display has been set to the “ON” mode. This allows your display to enter a
Power Saving Mode when no signal is applied. This could potentially increase the life and decrease the power
consumption of the display.
Selecting a video source To view a video source:
Use the input button to set [VIDEO].
Use the COLOR SYSTEM menu to set [AUTO], [NTSC], [PAL], [SECAM], [PAL60], [4.43NTSC], according to your video

NOTE 1: IMAGE PERSISTENCE
y Please be aware that LCD Technology may experience a phenomena known as Image Persistence. Image Persistence
occurs when residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD
monitors’ image persistence is not permanent, but constant images being displayed for a long period of time should be
avoided.
y To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an
image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to
erase the image.
y As with all personal display devices, ViewSonic recommends displaying moving images and using a moving screen
saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.
Please set “POWER SAVE”, “SCREEN SAVER”, “DATE &TIME” and “SCHEDULE” functions to further reduce the risk
of Image persistence.
ViewSonic CD4220

For long life use of Public Display
< Image Sticking of LCD Panel >
When LCD panel is operated continuously for long hours, a trace of electric charge remains near the electrode inside
LCD, and residual or “ghost” image of previous image may be observed. (Image Persistence)
Image Persistence is not permanent, but when fixed image is displayed for long period, ionic impurities inside LCD are
accumulated along the displayed image, and it is observed permanently. (Image Sticking)
< Recommendations >
For preventing the fast transition to Image Sticking, and for longer life usage of LCD, following are recommended.
1. Fixed image should not be displayed for long period, and changed to another images with short cycle.
2. When no use, please turn off the monitor by remote control, or use Power Management Function of monitor or use
Schedule Function of monitor.
3. Reducing the environmental temperature is effective for long life use.
4. Please use "Screen Saver Mode" of monitor.
NOTE 2: HOW TO SETUP SCHEDULE
y Using the “SCHEDULE” function allows you to set up to seven different scheduled time intervals when the LCD Monitor
will be activated.
y You can select the time the monitor turns on and turns off, the day of week the monitor is activated, and which input
source the monitor will use for each scheduled activation period. A check mark in the box next to the number of the
schedule indicates that the selected schedule is in effect.
y To select which schedule to set, use the up/down arrows to move the number (1 to 7) of the schedule.
y Use the (+) and (-) buttons to move the cursor horizontally within the particular schedule. Use the (S) and (T) buttons
to increase time and select input port. The “SET” button is used to make a selection.
y If you create a schedule but do not want to use a power on time, select “--” in the “ON” time slot.
y If you do not want to use a power off time select “--” in the OFF time slot.
y If there is no input selected (“--” showing in the input spot) the input from the previous schedule will be used.
y The selection of EVERY DAY within a schedule takes priority over other schedules that are set up to operate weekly.
y When schedules are overlapping, scheduled Power ON time has priority over scheduled Power OFF time.
y If there are two schedules programmed for the same time, then the highest numbered schedule has priority.
When the “OFF TIMER” is set, the “SCHEDULE” function is disabled.
