5-2. Imaging Problems (For Both Digital and Analog)
Problem Possible cause and remedy
1. The screen is too bright or too dark. • Use “Brightness” or “Contrast” in the Setting menu to
adjust it (see “Color Adjustment” (page 18)). (The LCD
monitor backlight has a limited life span. If the screen
becomes dark or begins to icker, contact your local EIZO
representative.)
• If the screen is too bright, try changing the Auto EcoView
setting to “On”. The monitor detects the ambient
brightness to adjust the screen brightness automatically
(see “Auto EcoView” (page 14)).
2. “Brightness” cannot be adjusted When Auto EcoView is set to “On”, “Brightness” may not be
adjustable due to the advanced settings of Auto EcoView.
• Cannot increase/decrease setting value (“
”
or “
” is displayed in gray)
- “Brightness” adjustment menu via
operation switch

- “Brightness” adjustment menu in color

/
• The bright adjustment range of the Auto EcoView function
can be limited to ensure that the screen is neither too
bright nor too dark. When the adjustment range is limited,
values outside the range cannot be set. If you want to
set a value outside the range, try changing the following
settings.
- Change the maximum and minimum values for
“Brightness” in the Auto EcoView advanced settings.
- Set Auto EcoView to “Off”.
For details on Auto EcoView settings, see “Auto EcoView”
(page 14).
• Cannot increase/decrease setting value (“
”
and “
” are displayed in gray)
- “Brightness” adjustment menu via
operation switch
- “Brightness” adjustment menu in color
adjustment
• Brightness adjustment may not be possible when the
installation environment of the monitor is excessively
bright or dark. In this case, try changing the following
settings.
- Change the maximum and minimum values for “Ambient
Light” in the Auto EcoView advanced settings.
- Set Auto EcoView to “Off”.
For details on Auto EcoView settings, see “Auto EcoView”
(page 14).
3. Text is blurred
• Check whether the PC is congured to meet the resolution
and vertical scan frequency requirements of the monitor
(see “1-3. Supported Resolutions” (page 10)).
• When an image is displayed with a resolution other than
recommended, text or lines in the displayed image may
blur. In this case, try adjusting “Sharpness” in the Setting
menu (see “Sharpness” (page 21)).
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.
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.
5. Green / red / blue / white dots or dark 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.
• Leave the monitor with a white or black screen. The
symptom may disappear.
