Chapter 5 Troubleshooting
Possible cause and remedy
• Use "Brightness" or "Contrast" in the Setting menu to adjust it (see
"Color Adjustment" (page
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
• Try changing the Auto EcoView setting to "Off" (see
(page
14)).
• Check whether the PC is configured to meet the resolution and
vertical scan frequency requirements of the monitor. For the method
for changing PC settings, refer to our website (www.eizoglobal.com).
• Try setting the magnification of display on the OS to "100%". When
using multiple monitors, try setting the magnification of display to
"100%" on all monitors.
• 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.
• This is due to LCD panel characteristics and not a malfunction.
• Leave the monitor with a white or black screen. The symptom may
disappear.
• In the Setting menu, set "Overdrive" to "Off" (see
19)).
• When inputting HDCP system signals, normal images may not be
displayed immediately.
• Turn the setting "On" for "Compatibility Mode" on the "Administrator
Settings" menu (see
"Compatibility Mode" (page
• Try changing "Input Color Format" in the Setting menu (see
Color Format" (page
21)).
• Try changing "Picture Expansion" in the Setting menu (see
Expansion" (page
20)).
• Check whether the setting for the resolution of the PC matches the
resolution of the monitor.
