TROUBLESHOOTING
Nothing is displayed on the screen.
Is the monitor's power cord plugged in?
•
•
•
Check if the power cord is correctly plugged into the power outlet.
Check your power cable connection and turn the power switch on.
Is the power indicator on?
Is the power indicator displaying as green?
Check if the input setting is correct when the PC and the product are
connected. (MENU > Quick Settings > Input)
Is the "Out of Range" message
displayed?
•
This occurs when the signals transferred from your PC (graphics card)
are outside the horizontal or vertical frequency range of your monitor.
Please see the "Product Specification" section of this manual to set the
appropriate frequency.
Is the 'No Signal' message displayed?
•
This is displayed when the signal cable between the PC and the monitor
is missing or disconnected. Check the cable and reconnect it.
The screen may not be displayed
properly when configuring DisplayPort
(DisplayPort) 1.2 in a Mac product.
•
DisplayPort 1.2 may not be supported depending on the Mac product.
Please contact the manufacturer.
The screen retains an image.
Does image sticking occur even when the
monitor is turned off?
•
•
Displaying a still image for a prolonged period may damage the screen,
resulting in image sticking.
To extend the lifetime of the monitor, use a screensaver.
The 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.
29
NOTE
•
Check if your graphics card's resolution or frequency is within the range supported by your monitor and set your
graphics card to the recommended (optimal) resolution in Control Panel > Display > Settings in Windows. (The
settings may differ depending on your operating system)
•
•
Not setting your 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 method may differ depending on the computer and operating system. Some resolutions may not be
available depending on your graphics card's performance. If this is the case, contact the manufacturer of your
computer or graphics card for help.
•
Some graphics cards may not support the 3840 x 2160 resolution. If the resolution cannot be displayed, contact the

Transmission/Reception Protocol
Transmission
[Command1][Command2][ ][Set ID][ ][Data][Cr]
[Command 1]: j, k, m, x
[Command 2]: This command is used to control the monitor.
[Set ID]: Used to identify the monitor being controlled. [Set ID] can be assigned to each monitor under GENERAL in the
Settings Menu.
A value from 1 to 10 can be assigned. By selecting '0' for the [Set ID] value in the protocol format, you can
control all connected monitors.
* The value is displayed as base 10 on the OSD menu and used as base 16 (0x00 - 0x63) in the
transmission/reception protocol for remote control.
[Data]: Transmits a setting value (Data) required for the command described previously. (base 16)
When the Data ‘FF’ is sent, the setting value corresponding to the specific command is read (Data read mode).
[Cr]: Carriage return, which is ‘0x0D’ in ASCII code.
[
]: Space, which is ‘0x20’ in ASCII code.
OK Acknowledgment
[Command2][ ][Set ID][ ][OK][Data][x]
When the Data has been successfully received, the monitor sends an ACK response signal in the above format. The
Data showing the current state is received in the Data read mode. The Data from the PC is simply returned in the Data
write mode.

Error Acknowledgment
[Command2][ ][Set ID][ ][NG][Data][x]
When the set receives an abnormal piece of Data for an unsupported function or there is a communication error, it
returns ACK in the format above.
