Possible cause and remedy
• Use "Brightness" or "Contrast" in the Setting menu to
adjust it (see "To perform advanced adjustments" (page
17)). (The LCD monitor backlight has a limited life
span. When the screen becomes dark or begins to flicker,
contact your local EIZO representative.)
• If the screen is too bright, turn on Auto EcoView and
EcoView Optimizer (see
Automatic Brightness Adjustment "Auto EcoView"" (page
37), "5-4. Reducing Glare "EcoView Optimizer"" (page
38)). The monitor detects the environmental brightness
to adjust the screen brightness automatically.
• Check whether the PC is configured to meet the resolution
and vertical scan frequency requirements of the monitor
(see "2-1. Compatible Resolutions/Formats" (page
• Use "Smoothing" in the Setting menu to adjust it (see
modify blurred characters/lines" (page
• Afterimages are particular to LCD monitors. Avoid
displaying the same image for a long time.
• Use the screen saver or power save function to avoid
displaying the same image for extended periods of time.
• This is due to LCD panel characteristics and is not a
failure.
• Leave the monitor with a white or black screen. The
symptom may disappear.
• In the Setting menu, set "Overdrive" to "Off" (see
overdrive intensity" (page
• When entering the HDCP signals, the normal images may
not be displayed immediately.
• Use "Black Level" (see "To Adjust Black Level "Black
Level"" (page 18)), and "Contrast" (see
contrast" (page 18)) in the Setting menu to adjust it.
• Change the color space of the video signal in "Screen" –
"Color Space" under the Setting menu.(see
the Color Space for the HDMI input signal" (page
• Transmittable signals differ on the category of the HDMI
cable. Check whether the cable support High Speed.
• Use "Screen" – "Color Space" under the Setting menu to
adjust it.(see "2-4. Setting the Color Space for the HDMI
input signal" (page 23))
