2. The screen is too bright or too dark.
• Adjust using “Brightness”, “Contrast” or “Backlight” (see page
15, page 16). (The LCD monitor backlight has a fixed life span.

your local EIZO representative.)

3. No sound
• Check whether the audio cable is connected properly.

4. Green/red/blue/white dots or
defective dots remain on the

marks remain on the screen.
• Leave the monitor with a white or black screen. The symptom
may disappear.
6. Afterimages appear.
• Afterimages are particular to LCD monitors. Avoid displaying
the same image for a long time.
• Use the screen saver or power save function to avoid
displaying the same image for extended periods of time.
