Chapter 7 Troubleshooting
7-2. Imaging problems (for both digital and analog)
Problem Possible cause and remedy
1. The screen is too bright or too dark. • Use “Brightness” in the Adjustment menu to adjust it. (The
LCD monitor backlight has a limited life span.) When the
screen becomes dark or begins to icker, contact your
local EIZO representative.)
2. Characters are blurred. • Check whether the PC is congured to meet the resolution
and vertical scan frequency requirements of the monitor
(see “2-1. Setting Resolution” (page 15)).
3. 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.
4. Green/red/blue/white dots or defective
dots remain on the screen.
• This is due to LCD panel characteristics and is not a
failure.
5. Interference patterns or pressure marks
remain on the screen.
• Leave the monitor with a white or black screen. The
symptom may disappear.
6. Noise appears on the screen. • In the Adjustment menu, set “Overdrive” to “Off” (see “2-5.
Conguring Moving Image Performance” (page 30)).
• When entering the signals of HDCP, the normal images
may not be displayed immediately.
7. The auto adjustment function does not
work.
• This function does not work during digital signal input.
• This function is intended for use on the Macintosh and
on AT-compatible PC running Windows. It does not work
properly when an image is displayed only on a part of the
screen (command prompt window, for example) or when a
black background (wallpaper, etc.) is in use.
• This function does not work correctly with some graphics
boards.
7-3. Imaging problems (for digital only)
Problem Possible cause and remedy
1. (DisplayPort input)
Display position of the windows changes.
• When the signal is switched, the position of the window
may be changed. In the Adjustment menu, set “DP Power
Save” to “Off” (see “6-5. Setting DisplayPort Power Save”
(page 44)).
2. (DisplayPort or HDMI input) The color
shown on the display is not correct.
• Use “Screen” - “Color Space” under the Adjustment menu
to adjust it. (see “2-6. Specifying Color Space” (page
30)).
• For HDMI signal input, change the “Signal Format” setting
(see “To switch signal formats (Only for HDMI signal
input)” (page 16)).
3. An image does not display on the entire
screen.
• Change the “Screen Size” setting (see “To select screen
size” (page 17)).
