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 23)). (The LCD
monitor backlight has a limited life span. When 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 18)).
2. “Brightness” cannot be adjusted When Auto EcoView is set to “On”, “Brightness” may not be adjustable due to the advanced settings of Auto EcoView.

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”.

dark. In this case, try changing the following settings.
- Change the maximum and minimum values for “Ambient Light” in the Auto EcoView advanced settings.
- Set Auto EcoView to “Off”.
For details on Auto EcoView settings, see “Auto EcoView” (page 18).
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 11)).
• 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 “Sharpness” (page 27)).
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.
