The screen retains an image.
Does image sticking occur even
when the monitor is turned off?
yDisplaying a still image for a prolonged time may cause damage to
the screen, resulting in the retention of the image.
yTo extend the lifetime of the monitor, use a screensaver.
Screen display is unstable and shaky / Images displayed on the monitor leave shadow trails.
Did you select the appropriate
resolution?
yIf the selected resolution is HDMI 1080i 60/50 Hz (interlaced), the
screen may be flickering. Change the resolution to 1080P or the
recommended resolution.
yVertical Frequency In order to display an image, the screen must be refreshed dozens of times per
second, like a fluorescent lamp. The number of times the screen is refreshed per second is called
vertical frequency, or refresh rate, and is represented by Hz.
yHorizontal Frequency The time it takes to display one horizontal line is called the horizontal cycle. If
1 is divided by the horizontal interval, the result is the number of horizontal lines displayed per second.
This is called horizontal frequency and is represented by kHz.

yCheck if the graphics card's resolution or frequency is within the range allowed by the monitor and set it
to the recommended (optimal) resolution in Control Panel > Display > Settings.

dimmed screen, a truncated display area, or misalignment of the display.
yThe setting methods may be different depending on the computer or operating system, and some
resolutions may not be available depending on the performance of the graphics card. If this is the case,
contact the manufacturer of the computer or graphics card for assistance.
