TROUBLESHOOTING
Is your monitor connected to your
Mac?
•• Connect your monitor to your Mac. The monitor will turn on automatically if the PC
is operating normally.
Is the monitor's power cord plugged
in?
•• Check if the power cord is correctly plugged into the power outlet.
The screen retains an image.
Does image sticking occur even when •• Displaying a still image for a prolonged time may cause damage to the screen,
the monitor is turned off?
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?
•• Set your monitor to the recommended (optimal) resolution.
•• Update your Mac OS or driver to the latest version.
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.
•• 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 4096 × 2304 resolution. If the resolution cannot be displayed, contact the
manufacturer of your graphics card or Mac, please update your OS or driver to the latest version.
The display color is abnormal.
Does the display color appear
unstable or monochrome?
•• Check if the signal cable is connected properly. Reconnect the cable or reinsert the
PC's graphics card.
Are there spots on the screen?
•• When using the monitor, pixilated spots (red, green, blue, white, or black) 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.
The brightness cannot be adjusted. The ALS(Ambient Light Sensor) does not work.
Have you updated Mac OS or Host
for this operation?
•• The ambient light sensor operates in accordance with Mac OS. Some Mac OS doesn't
support the display ALS (Ambient Light Sensor).
•• You can also adjust the monitor brightness by controlling the menu or hot key of a
host manually.
