To adjust the tilt and height

To use the display comfortably

This display can be adjusted within the angles shown below.

This display is designed so that you can set it up at a comfortable viewing angle. Adjust the viewing angle of your display according to the height of the desk and chair, and so that light is not reflected from the screen to your eyes.

To enjoy clear sound from the builtin stereo speaker

To adjust the angles, grasp the lower sides of the LCD panel with both hands as shown below. Tilt the LCD panel adequately backward, then lift the LCD panel upward to the desired screen height, then adjust the screen tilt as desired. When adjusting the screen height and tilt, proceed slowly and carefully, being sure not to hit the LCD panel against the desk or the base of the display stand.

This monitor has a built-in stereo speaker in base of the display stand.

We recommend that you position the LCD panel slightly away from the display stand. High tones from the speaker may be muffled if the LCD panel is positioned immediately on top of the stand. Be careful not to drop any metal object into the speaker's vents as the speakers generate a magnetic field. Also, this magnetic field may affect data stored on magnetic tapes and discs. Be sure to keep magnetic recording equipment, tapes, and floppy discs away from the speaker’s opening. A duct is provided on the rear part of the display stand to boost the bass. Be sure not to block the duct with paper or other objects to ensure clear sound.

If the monitor is connected to a computer or video graphics board that is DPMS (Display Power Management Signaling) compliant, the monitor will automatically enter the power saving mode. It automatically enters the low power consumption mode when the user sensor detects the absence of a user. Power consumption state

1 low power consumption mode

green and orange alternate

1 Low power consumption mode (user sensor)

When the user sensor in the monitor detects the absence of a user, the monitor enters low power consumption mode after about 20 seconds. In low power consumption mode, the monitor is in a power saving state and shuts off power to all circuitry (except for that of the sensors) regardless of the setting of the computer.

The monitor returns to normal operation mode when the presence of a user is detected by the user sensor. When the monitor enters the power saving mode (as set according to the computer’s settings), the power saving mode takes precedence over the low power consumption mode. In this case, the monitor stays in the power saving mode regardless of the presence or absence of a user. To return the monitor to normal operation mode, reset the computer’s power saving mode.

DPMS defines three power saving states according to the state of the sync signals supplied from the computer. This monitor’s power consumption is input at approximately 3 W in all of these states if the power saving function is set to ON.

When your computer enters in the power saving mode, the input signal is cut and NO INPUT SIGNAL appears on the screen. After a few seconds, the monitor enters power saving mode.

The user sensor detects the presence/absence of a user up to a distance of approximately 60 cm from the screen surface. However, this distance may vary depending on the user’s clothes or the brightness of the surrounding area. If user detection fails due to the ambient conditions of the surrounding area, set the user sensor to OFF. If your monitor does not automatically return from low power consumption mode due to the failure of the user sensor to detect the presence of a user, press the 1 (power) switch twice to turn the monitor off and then on.

US Automatic brightness adjustment function (light sensor)

This monitor is provided with a feature to automatically adjust the screen brightness according to the brightness of the surroundings. The brightness of the backlight is set to the most appropriate level by setting the light sensor to ON. The default setting of the brightness of the backlight is set to its maximum. When the light sensor setting is set to ON, the monitor adjusts the brightness of the backlight linearly from its lower- to upper-limit values. When the user adjusts the backlight, the backlight brightness is automatically adjusted between the user adjustment value and the upper- and lower-limit values. Backlight brightness

Automatic picture quality adjustment function

When the monitor receives an input signal, it automatically matches the signal to one of the factory preset modes stored in the monitor’s memory to provide a high quality picture at the center of the screen. (See Appendix for a list of the factory preset modes.) For input signals that do not match one of the factory preset modes, the automatic picture quality adjustment function of this monitor automatically adjusts the picture position, phase, and pitch, and ensures that a clear picture appears on the screen for any timing within the monitor’s frequency range (horizontal: 30 – 61 kHz, vertical: 50 – 85 Hz). Consequently, the first time the monitor receives input signals that do not match one of the factory preset modes, the monitor may take a longer time than normal for displaying the picture on the screen. This adjustment data is automatically stored in memory so that next time, the monitor will function in the same way as when the monitor receives the signals that match one of the factory preset modes. In all modes as above, if the picture is adjusted, the adjustment data is stored as a user mode and automatically recalled whenever the same input signal is received. Note on the adjusting the phase If the automatic picture quality adjustment function is activated, the picture moves slightly whenever the monitor receives the input signal, regardless of the stored adjustment.

While the automatic picture quality adjustment function is activated, only the 1 (power) switch, and INPUT button will operate.
