Problem Possible cause and remedy
1. The screen is too bright or too dark. • Use "Brightness" in the Setting menu to adjust it. (see
“Color” (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.
2. 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.
3. Green/red/blue/white dots or defective dots
remain on the screen.
• This is due to LCD panel characteristics and not a
malfunction.
4. Interference patterns or pressure marks
remain on the screen.
• Display a white or black image over the entire screen.
The symptom may disappear.
5. Noise appears on the screen. • When inputting HDCP system signals, normal images
may not be displayed immediately.

return from power save mode, windows or
icons may have shifted position.
• In the Setting menu, set "DP Power Save" to "Off" (see
“DP Power Save” (page 28)).

the Setting menu (see “Signal Format” (page 28)).
