3-2. Imaging Problems
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.
5. 3D images are not shown
• Switch to 3D mode.
• Adjust 3D mode.
6. 3D images are strange
• Switch the displays of the left-eye signal and the right-
eye signal.
• In SIMUL mode, make sure that the left-eye image
signal and the right-eye image signal are input correctly.
