Troubleshooting
Possible cause and remedy

(page

If the screen becomes dark or begins to flicker, contact your
local EIZO representative.

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.

• Display a white or black image over the entire screen. The
symptom may disappear.
• When inputting HDCP system signals, normal images may not
