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 indicator on?  Check your power cable connection and turn the power switch 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.
