Notice for This Monitor
Notice for This Monitor
This product may not be covered by warranty for uses other than those described in the Setup Manual.
The specications noted in this manual are only applicable when using power cords and signal cables
specied by us.
Only use optional products manufactured or specied by us with this product.
It takes about 30 minutes for the performance of electrical parts to stabilize. Please wait 30 minutes or more
after the monitor power has been turned on, and then adjust the monitor.
Monitors should be used with “Backlight” set to relatively low brightness to minimize degradation of
luminosity caused by long-term use, and to maintain a stable display.
When the screen image is changed after displaying the same image for extended periods of time, an
afterimage may appear. Use the screen saver or power save function to avoid displaying the same image for
extended periods of time. Depending on the image, an afterimage may appear even if it was displayed for
a short period of time. To remove such a phenomenon, change the image or keep the power turned off for
several hours.
If the monitor displays continuously over a long period of time, dark smudges or burn-in may appear. To
maximize the life of the monitor, we recommend the monitor be turned off periodically.
Do not splash detergent or hot water on the surface of the LCD panel, or bring any open ames close to it.
Doing so may cause the coating on the monitor surface to peel off and leave distinguishing traces.
Periodic cleaning is recommended to keep the monitor looking new and to prolong its operation lifetime (refer
to “Cleaning” (page 4)).
The LCD panel is manufactured using high-precision technology. Although, missing pixels or lit pixels may
appear on the LCD panel, this is not a malfunction. Percentage of effective dots: 99.9994 % or higher.
The backlight of the LCD panel has a xed lifetime. Depending on the usage pattern, such as usage for
long continuous periods, the lifespan of the backlight may run out sooner, requiring replacement. When the
screen becomes dark or begins to icker, please contact your local EIZO representative.
Do not scratch or press on the surface of the LCD panel with any sharp objects, as this may result in surface
damage. Rubbing the surface using tissues may also scratch the surface.
When the monitor is cold and brought into a room or the room temperature goes up quickly, dew
condensation may occur on the interior and exterior surfaces of the monitor. In that case, do not turn the
monitor on. Instead wait until the dew condensation disappears, otherwise it may cause some damage to the
monitor.
(Cautions for the Use of the Touch Panel)
Be sure to note the following points. Otherwise, damage or a malfunction may result.
• Do not place any objects on the touch panel.
• Do not apply excessive pressure to, scratch, or poke the touch panel.
• Do not touch the touch panel with hard objects such as ball point pens or metals.

4Notice for This Monitor
Cleaning
The stains on the cabinet and panel surface can be removed by using the provided cleaning cloth.
Attention
• If water or other kinds of liquid are on the surface of the LCD panel, promptly wipe it off as it may disrupt touch
operations.
• Chemicals such as alcohol and antiseptic solution may cause gloss variation, tarnishing, and fading of the cabinet
or LCD panel, and also quality deterioration of the image.
• Never use thinner, benzine, wax, or abrasive cleaner as they may damage the cabinet or LCD panel surface.
To Use the Monitor Comfortably
• An excessively dark or bright screen may affect your eyes. Adjust the brightness of the monitor
according to the environmental conditions.
• Staring at the monitor for a long time tires your eyes. Take a 10-minute rest every hour.

Chapter 3 Troubleshooting
3-2. Imaging Problems (for Both Digital and Analog)
Problem Possible cause and remedy
1. The screen is too bright or too dark. • Use "Backlight" in the Adjustment menu to adjust it. (The
LCD monitor backlight has a limited life span. If the screen
becomes dark or begins to icker, contact your local EIZO
representative.)
2. The screen suddenly became dark.
/ It cannot be made brighter even by
increasing the "Backlight" value in the
Adjustment menu.
• The product always monitors its internal temperature.
If the internal temperature becomes high and exceeds
a certain level, brightness may be reduced to bring the
temperature down. In this case, the brightness level cannot
be set to be higher than a controlled level. This state will
return to the original when the internal temperature falls.
If the internal temperature becomes even higher, the power to
the monitor is automatically turned off.
3. Characters are blurred. • Check whether the PC is congured to meet the resolution
and vertical scan frequency requirements of the monitor (see
“5-3. Compatible Resolutions / Signal Formats” (page 27)).
4. Afterimages appear • Afterimages are particular to LCD monitors. Avoid displaying
the same image for a long time.
• Use the screen saver or power saving function to avoid
displaying the same image for extended periods of time. An
afterimage may appear even after a short time period has
elapsed depending on the displayed image. If this occurs,
changing the image or leaving the power off for a few hours
may solve the problem.
5. Green/red/blue/white dots or defective
dots remain on the screen.
• This is due to LCD panel characteristics and not a
malfunction.
6. Interference patterns or pressure marks
remain on the screen.
• Display a white or black image over the entire screen. The
symptom may disappear.
7. Cloudiness cannot be removed even
after wiping the screen. / There is dew
on the interior side of the glass.
• When cloudiness cannot be removed even after wiping the
screen, dew may have formed on the interior side of the glass
that protects the LCD panel. In this case, turn on the monitor
and display something on screen. The dew will disappear
after a while. Also, warming the glass using a hair dryer may
make the dew disappear more quickly. Dew appearing like
this on the interior side of the glass will not lead to product
failure or degradation.
