Does image sticking occur even
when the monitor is turned off?
Displaying a still image for a prolonged time may cause damage to
the screen, resulting in the retention of the image.

Screen display is unstable and shaky / Images displayed on the monitor leave shadow trails.
Did you select the appropriate
resolution?
If the selected resolution is HDMI 1080i 60/50 Hz (interlaced),
the screen may be flickering. Therefore, change the resolution to
1080p or the recommended resolution.
Vertical 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.
Horizontal 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.
