Power Management System
This monitor incorporates new circuitry for lowering energy usage
during idle time, following the Display Power Management Signalling
(DPMS) guide-lines of the Video Electronics Standards Association
(VESA), and is certified as exceeding the EPA's Energy Star program
for reduced power usage.
For the power saving feature to operate, the monitor must be used
with either a PC having power saving circuitry or a PC running screen
blanking software. The monitor has three power-saving states, and
the power saving operation is indicated by the power indicator on the
front panel.
When the power indicator is green, operation is normal. When the
power indicator is orange, the monitor is in a power saving mode. If
the power indicator is dark or blinks orange, press the power button to
turn on the monitor. If the power indicator is orange and you wish to
use the PC again, move your mouse pointer or touch a keyboard
button. When the monitor is not in use, save energy by turning it off.
Image Adjustment
This monitor has a microprocessor-based On Screen Display (OSD)
control system for adjusting the following items: Contrast, Brightness,
Horizontal width, horizontal position, vertical height and position, side
pincushion and trapezoid, zoom, Rotation, and color levels. When you
make adjustments to any of the above items, the microprocessor will
automatically memorize the adjustments you made. Your settings will be
maintained even if you turn off the monitor and turn it on again.
NOTE: The only time you may need to adjust the image settings again
is in the event you change video modes (for example, you may go from
a 640x480 video mode in DOS to an 800x600 video mode for windows).
In this event, you may need to adjust the image controls again to meet
the image display you desire. Now, the microprocessor will memorize
the new image settings you made in the 800x600 video mode, having
already stored your 640x480 image settings. From now on, when you
switch between a 640x480 mode and a 800x600 mode, the monitor will
recall each of the specific image settings you made in each of these
modes. More on image memory modes in the video memory modes
section.
10

Video Memory Modes
This multi-synchronous auto-scanning monitor can automatically
detect and display several video modes falling within the monitor's
scanning range of 30-65KHz Horizontal and 50-110Hz Vertical. In the
PC area, this relates to a maximum flicker free usable resolution of
1024x768 at a non-interlaced refresh rate of 75Hz Vertical.
For convenience, the monitor has a 35 mode memory, of which 7
modes come from the factory preset to popular video modes as
described below.
Modes15-35 are empty and can accept new video data.
If the monitor detects one of the above signals from your computer's
video card, it will recall that mode and any stored image adjustments
you may have made before. If the monitor detects a new video mode
that had not been present before or is not one of the above listed
factory presets, it will store a new mode automatically in one of the
blank (empty) memory modes (in this example, mode 15). When you
now adjust the OSD controls to your preference, these image settings
will also be stored in mode 15. Whenever your video card or PC
switches to the mode that the monitor recognizes as mode 15, your
personal image settings will also be recalled.

Polarity

A note about the video memory modes:
There is a total of 35 video memory modes, generally more modes than
you will use at any one time. Of these 35 modes, 7 are permanent,
factory fixed modes that cannot be changed, and another 7 are set at the
factory, but may be overwritten to make more room. The remaining 21
modes are left blank (empty). If you use up the 21 blank modes and still
have more new video modes, the monitor will store information in the
other 7 soft preset modes for the new mode storage. If additional new
modes are encountered, the monitor will delete the lowest memory mode
and add the new mode.
If you use a video card that has a number of resolutions and frequencies
that do not correspond to any of the monitor video modes set at the
factory, here's what will happen:
1) As the monitor encounters new video data, if you adjust the image
control icons, the monitor will save the new information in the next
available empty mode (mode 15 if this is the first new data
encountered).
2) If you have used up modes 15-35 with 21 new video modes, and the
monitor encounters another mode (36th mode), it will store the new
data in mode 15 and the old data of mode 15 is deleted.
In addition, If the monitor encounters 27th new video data, the old
data of mode 16 is deleted and 27th data will replace the mode 16,
with above method, when this monitor encounters new mode, it can
update from mode 15 to mode 35 sequentially and continuously.
Because the monitor is designed this way, you will always have the
most common 28 video modes generated by your graphics card
available with your own image settings recalled automatically.

Low Radiation Compliance (MPR II)
This monitor meets one of the strictest guidelines available today for
low radiation emissions, offering the user extra shielding and an anti-
static screen coating. These guidelines, set forth by a government
agency in Sweden, limit the amount of emission allowed in the
Extremely Low Frequency (ELF) and Very Low Frequency (VLF)
electromagnetic range.
Self Diagnostics
This monitor can sense when there is a possible problem present,
and informs you of this condition by presenting you with a Self
Diagnostics OSD. This OSD may pop up when it is On but no signal
is detected. In this case the message CHECK S/CABLE will be high
lighted, alerting you to check the signal cable connections.
DDC (Display Data Channel)
DDC is a communication channel over which the monitor
automatically informs the host system(PC) about its capabilities.This
monitor has three DDC functions; DDC1, DDC2B, DDC2AB. DDC1
and DDC2 carry out uni-directional communication between the PC
and the monitor. Under these situations, the PC sends display data to
the monitor but not commands to control the monitor servings.
DDC2AB has the function of bi-directional communication. For
example, the PC can fetch screen data from monitor and adjust the
screen with the PC keyboard.
NOTE: PC must support DDC functions to do this.
HELP Menu
The help menu, activated by selecting HELP Menu, gives you some
operating information about the monitor:
It is composed of the three sequential menus:
The first menu shows the total number of the preset, user mode and
current mode information, the second one shows the preset mode
data stored, and third one shows the user mode data stored.
Pressing the + key displays the next page.
Pressing the - key displays the preceding page.
