Possible cause and remedy
1. The screen is too bright or too dark.

monitor backlight has a limited life span. If the screen
becomes dark or begins to flicker, 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
).
2. Brightness changes on its own.
•
Try changing the Auto EcoView setting to “Off” (see

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”.

4. Text is blurred.
•
Check whether the PC is configured to meet the resolution
and vertical scan frequency requirements of the monitor
(see
“1-2. Supported Resolutions” (page 8)
•
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
5. 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.
6. Green / red / blue / white / dark dots remain
on the screen.
•
This is due to LCD panel characteristics and not a
malfunction.
7. Interference patterns or pressure marks
remain on the LCD panel.
•
Leave the monitor with a white or black screen. The
symptom may disappear.
