The screen retains an image.
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.
• To 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?
• If the selected resolution is HDMI 1080i 60/50 Hz (interlaced), the screen 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
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.
