Notice for this monitor

In order to suppress the luminosity change by long-term use and to maintain the stable luminosity, use of a monitor in
lower brightness is recommended.

The LCD panel is manufactured using high-precision technology. However, note that the appearance of any missing
pixels or lit pixels does not indicate damage to the LCD monitor.
Percentage of effective pixels: 99.9994% or higher.

The backlight of the LCD panel has a fixed life span. When the screen becomes dark or begins to flicker, please contact
your dealer.

Do not press on the panel or edge of the frame strongly, as this may result in the display malfunction, such as the
interference patterns, etc. If pressure is continually applied to the LCD panel, it may deteriorate or damage your LCD
panel. (If the pressure marks remain on the LCD panel, leave the monitor with a white or black screen. The symptom
may disappear.)

Do not scratch or press on the panel with any sharp objects, such as a pencil or pen as this may result in damage to the
panel. Do not attempt to brush with tissues as this may scratch the LCD panel.

When the monitor is cold and brought into a room or the room temperature goes up quickly, dew condensation
may occur inside and outside the monitor. In that case, do not turn the monitor on and wait until dew condensation
disappears, otherwise it may cause damage to the monitor.

When the screen image is changed after displaying the same image for extended periods of time, an afterimage may
appear. Use the screen saver or timer to avoid displaying the same image for extended periods of time.

To use the monitor comfortably

An excessively dark or bright screen may affect your eyes. Adjust the brightness of the monitor according to the
environmental conditions.

Staring at the monitor for a long time tires your eyes. Take a 10-minute rest every hour.

5-4 Glossary

Clock

The analog input monitor needs to reproduce a clock of the same frequency as the dot clock of the graphics system in
use, when the analog input signal is converted to a digital signal for image display.
This is called clock adjustment. If the clock pulse is not set correctly, some vertical bars appear on the screen.

DDC/CI (Display Data Channel/Command Interface)

VESA provides the standardization for the interactive communication of the setting information, etc. between a PC
and the monitor.

DVI (Digital Visual Interface)

DVI is a digital interface standard. DVI allows direct transmission of the PC’s digital data without loss.
This adopts the TMDS transmission system and DVI connectors. There are two types of DVI connectors. One is
a DVI-D connector for digital signal input only. The other is a DVI-I connector for both digital and analog signal
inputs.

DVI DMPM (DVI Digital Monitor Power Management)

DVI DMPM is a digital interface power-saving function. The “Monitor ON (operating mode)” and “Active Off
(power-saving mode)” are indispensable for DVI DMPM as the monitor’s power mode.

Gain

This is used to adjust each color parameter for red, green and blue. An LCD monitor displays the color by the light
passing through the panel color filter. Red, green and blue are the three primary colors. All the colors on the screen
are displayed by combining these three colors. The color tone can be changed by adjusting the light intensity (volume)
passing through each color’s filter.

Gamma

Generally, the monitor brightness varies nonlinearly with the input signal level, which is called “Gamma
Characteristic”. A small gamma value produces a low-contrast image, while a large gamma value produces a high­contrast image.

HDCP (High-bandwidth Digital Contents Protection)

Digital signal coding system developed to copy-protect the digital contents, such as video, music, etc. This helps
to transmit the digital contents safely by coding the digital contents sent via DVI terminal on the output side and
decoding them on the input side.
Any digital contents cannot be reproduced if both of the equipments on the output and input sides are not applicable
to HDCP system.

Phase

Phase means the sampling timing to convert the analog input signal to a digital signal. Phase adjustment is made to
adjust the timing. It is recommended that phase adjustment be made after the clock is adjusted correctly.

Range Adjustment

Range adjustment controls the signal output levels to display every color gradation. It is recommended that range
adjustment be made before color adjustment.

Resolution

The LCD panel consists of numerous pixels of specified size, which are illuminated to form images. This monitor
consists of 1680 (S2031W) / 1920 (S2431W) horizontal pixels and 1050 (S2031W) / 1200 (S2431W) vertical pixels.
At a resolution of 1680 x 1050 (S2031W) / 1920 x 1200 (S2431W), all pixels are illuminated as a full screen (1:1).

sRGB (Standard RGB)

International standard for “color reproduction and color space” among peripheral devices (such as monitors, printers,
digital cameras, scanners). sRGB allows Internet users to closely match colors as a simple color matching means for
the Internet use.

Temperature

Color temperature is a method to measure the white color tone, generally indicated in degrees Kelvin. The screen
becomes reddish at a low temperature, and bluish at a high temperature, like the flame temperature.
5000K: Slightly reddish white
6500K: Warm white like paper white
9300K: Slightly bluish white

TMDS (Transition Minimized Differential Signaling)

A signal transmission system for digital interface.

VESA DPMS (Video Electronics Standards Association - Display Power Management Signaling)

VESA provides the standardization of signals from PC (graphics board) for power saving of PC monitors. DPMS
defines the signal status between PC and monitor.

Hinweis zur Ergonomie :

Dieser Monitor erfüllt die Anforderungen an die Ergonomie nach EK1-ITB2000 mit dem Videosignal, 1680 ×
1050 (S2031W)/1920 × 1200 (S2431W), Digital Eingang und mindestens 60,0 Hz Bildwiederholfrequenz, non
interlaced. Weiterhin wird aus ergonomischen Gründen empfohlen, die Grundfarbe Blau nicht auf dunklem
Untergrund zu verwenden (schlechte Erkennbarkeit, Augenbelastung bei zu geringem Zeichenkontrast.)

Übermäßiger Schalldruck von Ohrhörern bzw. Kopfhörern kann einen Hörverlust bewirken.
Eine Einstellung des Equalizers auf Maximalwerte erhöht die Ausgangsspannung am Ohrhörer- bzw.
Kopfhörerausgang und damit auch den Schalldruckpegel.

„Maschinenlärminformations-Verordnung 3. GPSGV:
Der höchste Schalldruckpegel beträgt 70 dB(A) oder weniger gemäss EN ISO 7779“

[Begrenzung des maximalen Schalldruckpegels am Ohr]
