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.
Is the power LED on?	Check the power cable connection and press the power button.
Is the power on and the power LED displaying white?	Check that the connected input is enabled (Menu - Input).
Is the power LED blinking?	If the monitor is in sleep mode, move the mouse, or press any key on the keyboard, to switch the display on.Check if the computer is turned on.
Is the OUT OF RANGE message being displayed?	This occurs when signals transferred from the PC (video card) are out of the 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 reconnect it.
The screen may not be displayed properly when configuring DisplayPort 1.2 in a Mac product.	DisplayPort 1.2 may not be supported depending upon the Mac product. Please contact the manufacturer.

The OSD Lock message is being displayed.
Are some functions not available when you press the Menu button?	• The OSD is locked. Go to Menu > Settings and set OSD Lock to Off.

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.

NOTE

• Check if the video card's resolution or frequency is within the range allowed by the monitor and set it to the recommended (optimal) resolution in Control Panel > Display > Settings.
• Not setting the video 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 video card. If this is the case, contact the manufacturer of the computer or video card for assistance.
• Some video cards may not support 3440 x 1440 resolution. If the resolution cannot be displayed, contact the manufacturer of your video card.

The display color is abnormal.
Does the display appear discolored (16 colors)?	Set the color to 24 bit (true color) or higher. In Windows, go to Control Panel > Display > Settings > Color Quality.
Does the display color appear unstable or monochrome?	Check if the signal cable is connected properly. Reconnect the cable or reinsert the PC's video 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.Set the audio output of the PC to the monitor you are using. On Microsoft Windows, go to Control Panel > Hardware and Sound >Sound > set the monitor as default device.
