• Check if the computer is turned on.
Is the "The screen is not currently set
to the recommended resolution. If you
have no video or the screen flickers,
see the troubleshooting guide in the
product owner’s manual." message
being displayed?
• This occurs when signals transferred from the PC (graphics card) are out of the recommended horizontal or vertical frequency
range of the monitor. Please see the Product Specification section of this manual to set the appropriate frequency.
Is the "No Signal" message being
displayed?
• This is displayed when the signal cable between the PC and the monitor is missing or disconnected. Check the cable and

ENGLISH
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.
32
ENGLISH
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 >
Settings 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 2560 x 1440 (180 Hz or Higher) resolution. If the resolution cannot be displayed, contact the manufacturer of your graphics card.

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.
No sound from the headphone port.
Are images displayed using DP
(DisplayPort) or HDMI input without
sound?
• Make sure that the headphone port connections are made properly.
• Try increasing the volume with the joystick.
