Problem
Possible cause and remedy
1. The screen is too bright or too dark.
•
Use “Brightness” or “Backlight” in the Setting menu to
adjust it.
2. Text is blurred
•
Check whether the PC is configured to meet the
resolution and vertical scan frequency requirements
of the monitor (see “Compatible Resolutions” in the
Instructions for Use).
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.
•
An afterimage may appear even after a short time
period has elapsed depending on the displayed image.
If this occurs, changing the image or leaving the power
off for a few hours may solve the problem.
4. Green, red, blue, white dots or dark dots
remain on the screen
•
This is due to LCD panel characteristics and not a
malfunction.

screen does not become brighter after
increasing the “Backlight” value in the
Settings menu.
•
This product is equipped with a heat dissipation fan. If
the fan is not operating properly, screen brightness can
