POWER SAVING FUNCTION

This monitor meets the power-saving guidelines set by VESA, ENERGY STAR, and NUTEK. If the monitor is connected to a computer or video graphics board that is DPMS (Display Power Management Signaling) compliant, the monitor will automatically reduce power consumption in three stages as shown below.

Power mode	Power	1 (power)
	consumption*	indicator
normal	≤ 160 W	green
operation
1 standby	≤ 100 W	green and orange
		alternate
2 suspend	≤ 15 W	green and orange
		alternate
3 active off**	≤ 1 W	orange
power off	0 W	off

*Figures reflect power consumption when no USB compatible peripherals are connected to the monitor.

**When your computer enters the “active off” mode, the input signal is cut and NO INPUT SIGNAL appears on the screen. After the time set in “Changing the power saving delay time.” (page 1-6) has elapsed, the monitor enters the power saving mode.

DIAGNOSIS

This monitor is equipped with a self-diagnosis function. If there is a problem with your monitor or computer(s), the screen will go blank and the 1 (power) indicator will either light up green or flash orange. If the 1 (power) indicator is lit in orange, the computer is in power saving mode. Try pressing any key on the keyboard.

If all four color bars appear (white, red, green, blue), the monitor is working properly. Reconnect the video input cables and check the condition of your computer(s).

If the color bars do not appear, there is a potential monitor failure. Inform your authorized Sony dealer of the monitor’s condition.

If the 1 (power) indicator is flashing orange

Press the 1 (power) button to turn the monitor off and on.

If the 1(power) indicator lights up green, the monitor is working properly.
