POWER ON DELAY y Adjusts the delay time from "standby" to "power on" mode. y "POWER ON DELAY" time is selectable from OFF, 2sec, 4sec, 6sec, 8sec, 10sec, 20sec, 30sec, 40sec and 50sec.

ADVANCED OPTION RESET y Selecting ADVANCED OPTION reset allows you to reset all OSD settings from ADVANCED OPTION settings, except for DATE & TIME. y Select "YES" and press "SET" button to restore the factory preset data. y Press "EXIT" button to cancel and then return the previous menu. 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 31
