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: 1920 x 1080
• 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 6,220,800.  When cleaning the monitor and the panel outside, please apply a small amount
of  water 

to a soft cloth. Rub softly when cleaning the LCD area.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 ap-
peared  as  window  termination  button  is  pressed.  If  there's  still  noise  after  the
automatic adjustment, use the  Fine/Coarse adjustment function.  When viewing a fixed screen for an extended period of time, a residual image
or  blurriness 

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)
What is Image Retention ?
Image retention may not occur when a LCD panel is operated under normal con-
ditions.
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. 
						

							Power Off, Screen Saver, or Power Save Mode
• Turn the power off for 4 hours after 20 hours in use
• Turn the power off for 2 hours after 12 hours in use
• Set the Monitor to power off with the PC Display Properties Power Scheme.
• Use a Screen saver if possible - Screen saver in one color or a moving imageis recommended.
Change the Color Information periodically  Note
Use Two different colors
Rotate the Color Information with 2 different colors every 30 minutes. Information 
						

							• Avoid 
using a combination of characters and background color with large dif-
ference in luminance.
Avoid using Grey colors, which can cause Image retention easily.
Avoid: Colors with big difference in luminance (Black & White, Grey)Change the characters color periodically
• Use Bright colors with little difference in luminance.
- Cycle : Change the characters color and background color every 30 minutes • Every 30 minutes, change the characters with movement.
• Have the images and logo cycle periodically.
- Cycle: 

Display moving image together with Logo for 60 seconds after 4 hours
in use.
• The best way to protect your monitor from Image retention is to turn the Power off, or set your PC or System to operate a Screen Saver program when you are
not using it. If these guidelines are not followed, it may affect your warranty.

Terms Dot Pitch The image 
on a monitor is composed of red, green and blue
dots. The closer the dots, the higher the resolution. The dis-
tance between two dots of the same color is called the 'Dot
Pitch'. Unit: mm Appendix 
						

							Vertical Frequency
The 
screen  must  be  redrawn  several  times  per  second  in
order to create and display an image for the user. The fre-
quency  of  this  repetition  per  second  is  called  the  Vertical
Frequency or Refresh Rate. Unit: Hz
Example:  If  the  same  light  repeats  itself  60  times  per  sec-
ond, this is regarded as 60 Hz.
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. The inverse number of the Horizontal Cycle is called
Horizontal Frequency. Unit: kHz
Interlace  and  Non-Interlace
Methods Showing  the  horizontal  lines  of  the  screen  from  the  top  to
the bottom sequentially is called the Non-Interlace method
while showing odd lines and then even lines in turn is called
the Interlace method. The Non-Interlace method is used for
the majority of monitors to ensure a clear image. The Inter-
lace method is the same as that used in TVs.
Plug & Play This  is  a  function  that  provides  the  best  quality  screen  for
the  user  by  allowing  the  computer  and  the  monitor  to  ex-
change information automatically. This monitor follows the
international standard VESA DDC for the Plug & Play func-
tion.
Resolution The number of horizontal and vertical dots used to compose
the  screen  image  is  called  the  'resolution'.  This  number
shows the accuracy of the display. A high resolution is good
for performing multiple tasks as more image information can
be shown on the screen.
Example:  If  the  resolution  is  1920  x  1080,  this  means  the
screen is composed of 1920 horizontal dots (horizontal res-
olution) and 1080 vertical lines (vertical resolution).
