• With this function, you can choose to let the LCD monitor display the input image in its original aspect 

ratio (when Original is selected), or force the LCD monitor to fill the input image on the entire display 

area (when Full is selected).

• Press the ENTER button on the remote control, or the Menu/Enter button on the control panel to 

change selection.

• Only available when HDMI is the input source.

• Turns on or off the over scan function when displaying HDMI input image.

• Press the ENTER button on the remote control, or the Menu/Enter button on the control panel to turn 

this function on or off.

• If turned on, the LCD monitor will go to power management mode when PC sync is lost, and will go to 

power management mode after about 10 minutes delay when DVD/HD and VIDEO input signal is lost.

• Press the ENTER button on the remote control, or the Menu/Enter button on the control panel to turn 

this function on or off.

• If turned on, the LCD monitor automatically displays swift moving patterns every 10 seconds to 

prevent the formation of image retention on the screen.

• Press the ENTER button on the remote control, or the Menu/Enter button on the control panel to turn 

this function on or off.

• 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.

• 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.

• 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.

• If turned on, when changing PC timing, the horizontal position, vertical position and clock-phase will 

adjust automatically.

• Press the ENTER button on the remote control, or the Menu/Enter button on the control panel to turn 

this function on or off.

• By connecting multiple CD4225 monitors to a PC using RS-232C cables, you can control any one 

monitor or all the monitors on the PC. Assign arbitrary ID number to each of multi-connected CD4225
