1.2Internal Preset Memory Capability
To minimize adjustment needs, the factory has preset popular display standards into the monitor, as shown in Table 1. If any of these display standards are detected, the picture size and center- ing are automatically adjusted. All of the factory presets may be overwritten by adjusting the user controls. The monitor is capable of automatically storing up to 6 additional display standards. The new display information must differ from any of the existing display standards by at least 1kHz for the horizontal scan frequency or 5Hz for the vertical scan frequency or the sync signal polarities must be different.

1.3Power Management Function
The monitor has the power management function which reduces the power consumption of the monitor when not in use. There are three reduced power level modes.
Stand-by mode
When the horizontal sync signal is off after about 10 seconds, the monitor is switched to a
After the horizontal sync signal is restored, picture will be displayed immediately.
Suspend mode
When the vertical sync signal is off, after about 10 seconds the monitor is switched to a suspend mode which reduces the monitor power consumption to less than 15W.
When the monitor is in suspend mode, the screen is off and the power indicator will change to amber. After the vertical sync signal is restored, picture will be displayed within a few sec- onds.
Power-off mode
When the horizontal sync signal and vertical sync signal are off, after about 10 seconds the monitor is switched to a
When the monitor is in
After both the sync signals are restored, picture will be displayed within several seconds.
