Troubleshooting
5-2. Imaging problems
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 21)
). (The LCD monitor backlight has a limited life
span. When the screen becomes dark or begins to flicker, 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.
•
Depending on the graphics board, the 4096 × 2160 signal may not be output normally, and noise may appear.
Check the graphics board specification.
6. (DisplayPort or HDMI input)
The screen looks strange.
•
Try changing “Input Color Format” in the Setting menu (see
“Input Color Format” (page 31)
).
•
For HDMI signal input, try changing “Signal Format” in the Setting menu (see
“Signal Format” (page 40)
).
7. The image does not display on the entire
screen.
•
Try changing “Picture Expansion” in the Setting menu (see
“Picture Expansion” (page 31)
).
•
Try changing “Signal Format” in the Setting menu (see
“Signal Format” (page 40)
).
•
Check if the resolution is set to 4096 × 2160. Refer to the User's Manual of the graphics board for details on the settings.
•
Depending on the graphics board, the 4096 × 2160 resolution may not be output. Check the graphics board specification.
