							Horizontal Frequency
The time to scan one line connecting the right edge to the
left 
edge 
of the screen horizontally is called the Horizontal
Cycle and the inverse number of the Horizontal Cycle is
called the Horizontal Frequency. Unit: kHz
Vertical Frequency
Like a fluorescent lamp, the screen has to repeat the same
image many 
 times per second to display an image to the
user. The frequency of this repetition is called the Vertical
Frequency or Refresh Rate. Unit: Hz

Plug and Play Capability This monitor can be installed on any Plug & Play compatible system. The interaction of the
monitor 
and 
the computer systems will provide the best operating conditions and monitor
settings. In most cases, the monitor installation will proceed automatically, unless the user
wishes to select alternate settings.
Dot Acceptable TFT-LCD panels manufactured by using advanced semiconductor technology with preci-

of 

1ppm  (one  millionth)  above  are  used  for  this  product.  But  the  pixels  of  RED,
GREEN, BLUE and WHITE color appear to be bright sometimes or some black pixels may
be seen. This is not from bad quality and you can use it without any problems.
For example, the number of TFT-LCD sub pixels contained in this product are 5,292,000.  Note
Design and specifications are subject to change without prior notice.  Class B Equipment (Information Communication equipment for residential use)
This  product 

complies with the Electromagnetic Compatibility Directives for residential use and can
be used in all areas including common residential areas. (Class B equipment emits less electromagnetic
waves than Class A equipment.)
PowerSaver This monitor has a built-in power management system called PowerSaver. This system saves energy
by switching your monitor to low-power mode when it has not been used for a certain amount of time.
The  monitor  automatically  returns  to  normal  operation  when  you  press  a  key  on  the  keyboard.  For
energy conservation, turn your monitor OFF when it is not needed, or when leaving it unattended for
long periods. The PowerSaver system operates with a VESA DPM compliant video card installed in
your computer. Use the software utility installed on your computer to set up this feature.

For Better Display
 Adjust the computer resolution and screen injection rate (refresh rate) on the computer
as  described 
below to enjoy the best picture quality. You can have an uneven picture quality
on screen if the best picture quality is not provided for TFT-LCD.
• Resolution: 1440 x 900
• Vertical frequency (refresh rate): 60 Hz  TFT-LCD panels manufactured by using advanced semiconductor technology with a
precision  of 

1ppm (one millionth) and above is used for this product. But the pixels of RED,
GREEN, BLUE and WHITE color seem to be bright sometimes or some of black pixels
could be seen. This is not from bad quality and you can use it without any problems.
• For  example,  the  number  of  TFT-LCD  sub  pixels  contained  in  this  product  are 3,888,000.  When cleaning the monitor and the panel outside, please apply the recommended small
amount  of 

cleaner by using a soft cloth to polish. Do not force the LCD area but rub softly.
If excessive force is applied, you may stain it.  If you are not satisfied with the picture quality, you can get better quality of picture by
performing  the 

"Auto Adjustment  function" in display screen that is appeared as window
termination button is pressed.
If there's still noise after the automatic adjustment, use the  Fine/Coarse adjustment func-
tion.  When viewing a fixed screen for an extended period of time, a residual image or blur-
riness may appear.
Change  the 

mode to energy save or set a screensaver to move the picture when you need
to be away from the monitor for an extended period of time.

PRODUCT INFORMATION (Image Retention Free) LCD Monitors 

and TVs may have image retention when switching from one image to another espe-
cially after displaying a stationary image for a long time.
This  guide  is  to  demonstrate  correct  usage  of  LCD  products  in  order  to  protect  them  from  Image
retention.  Warranty
Warranty does not cover any damage caused by image retention.
Burn-in is not covered by the warranty.  What is Image retention ?
84
 
						

							During normal operation of a LCD panel, pixel image retention doesn't occur. However, if
the 
same 
image is displayed for a long time, a slight difference in electric charge accumu-
lates between the two electrodes which encase the liquid crystal. This may cause the liquid
crystal  to  build  up  in  a  certain  areas  of  the  display.  Thus,  the  previous  image  is  retained
when switching to a new video image. All display products, including LCD, are subject to
image retention. This is not a product defect.
Please follow the suggestions below to protect your LCD from image retention.  Power Off, Screen Saver, or Power Save Mode
Ex)
• Turn the power off when using a stationary pattern.
•

Turn the power off for 4 hours after 20 hours in use
• Turn the power off for 2 hours after 12 hours in use
• Use a Screen saver if possible • Screen saver in one color or a moving image is recommended.
• Set the Monitor to power off with the PC Display Properties Power Scheme.  Suggestions for specific applications
Ex)  Airports, 

Transit Stations, Stock Markets, Banks, and Controlling Systems We recom-
mend that you follow set up of your display system program as below:  Display Information together with Logo or Moving image cycle.
Ex)  Cycle 

: Display Information for 1 hour followed by a Display Logo or moving image
for 1 minute.  Change the Color Information periodically (Use 2 different colors).
Ex) Rotate the Color Information with 2 colors every 30 minutes. Avoid  using  a  combination  of  characters  and  background  color  with  large  difference  in
luminance.
Avoid using Grey colors, which can cause Image retention easily.
•
Avoid: Colors with big difference in luminance (Black & White, Grey)
Ex) Information
85
 
						

							• Recommended settings: Bright colors with little difference in luminance
•Change the characters color and background color every 30 minutes
Ex) • Every 30 minutes, change the characters with movement.
Ex)  
The  best way to protect your monitor from Image retention is to set your PC or System
to operate a Screen Saver program when you are not using it.
Image retention may not occur when a LCD panel is operated under normal conditions.
Normal 
conditions  are  defined  as  continuously  changing  video  patterns.  When  the  LCD
panel is operated for a long time with a fixed pattern (-over 12 hours-), there may be slight
difference in voltage between electrodes that work the liquid crystal (LC) in a pixel. The
voltage difference between electrodes increases with time, forcing the liquid crystal to lean.
When this occurs, the previous image may be seen when the pattern is changed.
To prevent this, the accumulated voltage difference must be decreased. Information
