Display recreates visual signals received from the computer. Therefore, if there is a
problem  with  the  computer  or  the  video  card,  this  can  cause  the  LCD  Display  to  become
blank, have poor coloring, become noisy, etc. In this case, first check the source of the prob-
lem, and then contact a Service Center or your dealer.
1. Check if the power cord and the video cables are properly connected to the computer.
2. Check if the computer beeps more than 3 times when booting.
(If it does, request service.)
3. If you installed a new video card or if you assembled the PC, check if you installed the Adaptor(video).
4. Check if the scanning ratio of the video screen is set to between 50 Hz ~ 85 Hz. (Do not exceed 60Hz when using the maximum resolution.)
5. If you have problems in installing the Adaptor (video) driver, boot the computer in Safe Mode, remove the Display Adaptor in the "Control Panel −> System −> Device Admin-
istrator" and then reboot the computer to reinstall the Adaptor (video) driver.

							Plug and Play Capability
This  LCD  Display  can  be  installed  on  any  Plug  &  Play  compatible  system.  The
interaction 
of 
the LCD Display and the computer systems will provide the best op-
erating  conditions  and  LCD  Display  settings.  In  most  cases,  the  LCD  Display
installation  will  proceed  automatically,  unless  the  user  wishes  to  select  alternate
settings.
Dot Acceptable TFT-LCD panels manufactured by using advanced semiconductor technology with
precision 
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
6,220,800.  Note
Design and specifications are subject to change without prior notice.  Note

PowerSaver This LCD Display has a built-in power management system called PowerSaver. This system
saves energy by switching your LCD Display to low-power mode when it has not been used
for a certain amount of time. The LCD Display automatically returns to normal operation when
you press a key on the keyboard. For energy conservation, turn your LCD Display 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.

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 Hor-
izontal  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 Specifications
