SETUP
PRODUCT FEATURES
CONNECTING THE D-SUB SIGNAL CABLE
• The convenient and user-friendly on-screen display allows for
easy and accurate adjustments of horizontal and vertical
screen size and position, geometry and screen color.
1. Turn off the computer and monitor.
2. Connect the 15 pin D-sub connector to the output port of the
video card in your computer and monitor.
• The monitor supports a safe working environment in strict
compliance with the MPR II standard for low emissions
(TCO optional).
3. Tighten the screws of connector.
• The monitor complies with the VESA Display Data Channel
(DDC) specification for Plug and Play compatibility.
Advanced microcircuitry makes setup and configuration fast
and effortless.
• The monitor features Advanced Color Controls for fine-tuning
to meet your own personal tastes or application requirements.
Use the on-screen controls to adjust the color temperature,
RGB gain value for the best possible screen color and
intensity.
• Press the menu button and activate the Self-Diagnosis menu to
determine whether your monitor is functioning normally, not
receiving a signal or is receiving a signal that is out of
scanning range.
• Activate the higher refresh rates of the monitor to stabilize the
screen and eliminate the annoying flicker that contributes to
eye-strain and headaches.
• The “borderless” full-screen display capability works under all
graphic modes and provides a larger viewing area than
conventional monitors, giving you a better picture with more
workspace.

CONNECTING THE BNC SIGNAL CABLE
CONNECTING THE POWER CORD
1. Plug the power cord into the AC receptacle located at the back
of the monitor.
1. Turn off the computer and monitor.
2. Connect the 5 BNC connectors from the signal cable to the
monitor.
2. Plug the other end of the power cord into the AC outlet.
3. Push in and turn the connectors clockwise until they are
locked in place.
If your power cord is PC-to-Monitor type, plug the other end
of the power cord into the AC receptacle in the computer.
POWER MANAGEMENT SYSTEM
If you use the monitor with a computer that complies with the
power-saving program, you can set the monitor to go blank when
the system has remained unused for a period of time. To specify
the period or to disable this feature, set the system timeout field
of the computer’s system setup program or use special software
for power-saving. See the computer user’s manual for the details
of using the system setup. While the monitor is in power-saving
mode (blank screen), it consumes less power than when it is in its
normal state. The color of the power LED will indicate the state.
To restore the screen image, press any key of your keyboard or
move your mouse. If the signal cable is connected loosely or
disconnected, the power-saving feature will not operate.

DISPLAY DATA CHANNEL FOR PLUG AND PLAY
BNC signal cable
(Optional Accessory)
If you use the monitor with a computer that complies with
DDC1/2B/CI of VESA, the host video card automatically
configures itself without your intervention in a way that best fits
the attached monitor. The Display Data Channel(DDC) allows
the monitor to inform the host system about configuration
information for optimum use of the monitor. Use of the video
card utility is not required to match the resolutions and refresh
rates of the monitor and video card.
