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.
• Check if the graphics card’s resolution or frequency is within the range allowed by the monitor and set it to the recommended (optimal) resolution Control Panel > Display >
Menu in Windows. (The settings may differ depending on the operating system (OS) you use.)
• Not setting the graphics card to the recommended (optimal) resolution may result in blurred text, a dimmed screen, a truncated display area or misalignment of the display.
• The 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.
• Some graphics cards may not support 1920 x 1080 resolution. If the resolution cannot be displayed, contact the manufacturer of your graphics card.
