5-2. Imaging Problems
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 19)). (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 16)).
2. Brightness cannot be changed or
it changes on its own.
• Try changing the Auto EcoView setting to “Off” (see “Auto EcoView”
(page 16)).
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)).
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 / 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.
7. Noise appears on the screen. • In the Setting menu, set “Overdrive” to “Off” (see “Overdrive” (page
21)).
• When inputting HDCP system signals, normal images may not be
displayed immediately.
8. The positions of windows and
icons are shifted when the
monitor is turned off / on or when
restored from power saving mode.
• Turn the setting “On” for “Compatibility Mode” on the “Administrator
Settings” menu (see “Compatibility Mode” (page 26)).
8. The color shown on the screen is
not correct.
• Try changing “Input Color Format” in the Setting menu (see “Input
Color Format” (page 22)).
9. Images are not displayed over the
entire area of the screen.
• Try changing “Picture Expansion” in the Setting menu (see “Picture
Expansion” (page 22)).
