Internal 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 by the microprocessor, the picture size and position are automatically adjusted. All of the factory presets may be overwritten by adjusting the user controls. This monitor is capable of automatically storing up to 15 additional display standards (22" model) or 16 additional display standards (17" and 19" models). The new display information must differ from any of the existing display standards by at least 1kHz for the horizontal scan frequency or 1Hz for the vertical scan frequency or the sync signal polarities must be different.

Power Management Function

The monitor has a power management function which reduces the power consumption of the monitor when not in use.

The power saving mode is invoked by a VESA DPMS- compliant computer. Check your computer's manual for setting this function.

22" Model

Mode	Power Power-On Indicator
	(with no USB
	operation)
Normal	140 W	Green
Power Saving Mode	< or = 5 W	Amber

19" Model

Mode	Power Power-On Indicator
Normal	120 W	Green
Power Saving Mode	< or = 5 W	Amber

17" Model

Mode	Power Power-On Indicator
Normal	95 W	Green
Power Saving Mode	< or = 5 W	Amber

DDC

The monitor includes the VESA DDCTM1 and DDCTM2B feature. DDC (Display Data Channel) is a communication channel over which the monitor automatically informs the computer system about its capabilities (e.g. each sup- ported resolution with its corresponding timing). DDC is routed through previously unused pins of the 15-pin VGA connector. The system will “Plug and Play” if both monitor and computer implement the DDC protocol.
