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