the keyboard, to switch the display on.

• Check if the computer is turned on.

Is the [OUT OF RANGE] message being displayed?

Is the [No Signal] message being displayed?

The OSD Lock message is being displayed.

Are some functions not available when you press the Menu button?

• This occurs when signals transferred from the PC (graphics 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.

• This is displayed when the signal cable between the PC and the monitor

is missing or disconnected. Check the cable and reconnect it.

• The OSD is locked. Go to [Menu] > [General] 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.

• 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 3840 x 2160 resolution. If the resolution cannot be displayed, contact the

manufacturer of your graphics card.
