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.

NOTE
Check if the graphics card's resolution or frequency is within the range allowed by the monitor and set it to the
y
recommended (optimal) resolution in Control Panel > Display > settings.
Not setting the graphics card to the recommended (optimal) resolution may result in blurred text, a dimmed
y
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
y
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 3840 x 2160 resolution. If the resolution cannot be displayed, contact the
y
manufacturer of your graphics card.
The display color is abnormal.
Does the display appear discolored (16

y
Panel > Display > Settings > Color Quality.
Check if the signal cable is connected properly. Reconnect the cable or
y
reinsert the PC's graphics card.
When using the monitor, pixilated spots (red, green, blue, white, or black)
y
may appear on the screen. This is normal for an LCD screen. It is not an
error, nor is it related to the monitor's performance.
Do you see an "Unrecognized monitor, Plug&Play (VESA DDC) monitor found" message?
Have you installed the display driver?
No sound from the headphone port or speaker.
Are images displayed using DisplayPort
or HDMI input without sound?
Be sure to install the display driver from our web site:
