through the AC/DC adapter.

3. VGA Signal-Plug one end of the 15-pin signal cable to the video signal connector

at the rear of the PC system and the other end to the monitor. Secure the
connectors with the screws on the cable connector at both ends.

4. (Optional) DVI Signal-Plug one end of the DVI signal cable to the video signal

connector at the rear of the PC system and the other end to the monitor. Secure
the connectors with the screws on the cable connector at both ends.

5. (Optional) HDMI Signal-Plug one end of the HDMI signal cable to the video

signal connector at the rear of the PC system and the other end to the monitor.
Secure the connectors with the screws on the cable connector at both ends.

6. (Optional) RS232 Connection- Plug one end of RS232 cable to com-port

connector on your PC system and the other end to the monitor. Secure the
connectors with the screws on the cable connector at both ends.

Panel Specification

Note 1: Measurement method
The LCD module should be stabilized at given temperature for 30 minutes to avoid abrupt temperature

change during measuring (at surface 35

). In order to stabilize the luminance, the measurement should be

executed after lighting Backlight for 30 minutes in a stable, windless and dark room.

Note 2: Definition of viewing angle measured by ELDIM (EZContrast 88)
Viewing angle is the measurement of contrast ratio

10, at the screen center, over a 180° horizontal and

180° vertical range (off-normal viewing angles). The 180° viewing angle range is broken down as follows;
90° (θ) horizontal left and right and 90° (Φ) vertical, high (up) and low (down). The measurement direction is
typically perpendicular to the display surface with the screen rotated about its center to develop the desired
measurement viewing angle.

Note 3: Contrast ratio is measured by TOPCON SR-3
Note 4: Definition of Response time measured by Westar TRD-100A

The output signals of photo detector are measured when the input signals are changed from “Full
Black” to “Full White” (rising time, T

rR

), and from “Full White” to “Full Black” (falling time, TrF),
respectively. The response time is interval between the 10% and 90% (1 frame at 60 Hz) of
amplitudes.
