Sony GDM-W900 operating instructions Plug & Play

Plug & Play

This monitor complies with the DDC™1, DDC2B and DDC2AB which are the Display Data Channel (DDC) standards of VESA.

When a DDC1 host system is connected, the monitor synchronizes with the V. CLK in accordance with the VESA standards and outputs the EDID (Extended Display Identification Data) to the data line.

When a DDC2B or DDC2AB host system is connected, the monitor automatically switches to each communication.

DDC™ is a trademark of Video Electronics Standard Association.

Damper Wire

Using a white background, very thin horizontal lines on the screen are visible as shown below. These lines are damper wires.

The Trinitron tube has a vertically striped Aperture Grill inside. The Aperture Grille allows more light to pass through to the screen giving the Trinitron CRT more color and brightness.

These damper wires are attached to the Aperture Grille to prevent vibration of the Aperture Grille wire so that the screen image is constantly stable.

Power Saving

Function

This monitor is capable of three states of reduced power consumption. By sensing the absence of video signals and one or both sync signals coming from the host computer, it will reduce power consumption as follows.

	Power	Power	Recovery	POWER	u (power)
	consumption	consump-	time	SAVING	indicator
	state	tion		indicator
1	Normal	≤ 200 W	—	Off	Green on
	operation
2	Standby	≤ 140 W	Approx.	Orange on	Green on
	(1st state)		3 sec.
3	Suspend	≤ 15 W	Approx.	Orange on	Green on
	(2nd state)		3 sec.
4	Active-off	≤ 8 W	Approx.	Orange on	Off
	(3rd state)		10 sec.
5	Power-off	0 W	—	Off	Off

Power saving operation

∙ The H-sync is not present.
	EN
/The unit goes into standby state.
∙ The V-sync is not present.	F
/The unit goes into suspend state.	D
∙ Both the H-sync and V-sync are not present.
/The unit goes into active-off state.	ES
The monitor requires a video card or screen saver software	I
which switches off one or both sync signals to activate the
power saving function.	J
Caution
If no video signal is input to the monitor, or if the INPUT
switch is set to the connector to which no signal is input
when you turn on the monitor, the input signal warning
indicator (page 18) appears. After 30 seconds, the Power
Saving function automatically puts the monitor into the
Active-off state and the POWER SAVING indicator lights
up. Once the horizontal and vertical syncs are sensed, the
monitor will automatically return to its Normal operation
state.
