TROUBLESHOOTING

Nothing is displayed on the screen.

Is the monitor’s power cord plugged in?| Ÿ  Check if the power cord is correctly plugged into the power outlet.
Is the power LED on?| Ÿ  Check the power cable connection and press the power button.
Is the power on and the power LED displaying white?| Ÿ  Check that the connected input is enabled (Menu > Input > Input list).
Is the OUT OF RANGE message being displayed?| Ÿ  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.
Is the No Signal message being displayed?| Ÿ  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 lock message is being displayed.
Are some functions not available when you press the Menu button?| Ÿ  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?| Ÿ  Displaying a still image for a prolonged time may cause damage to the screen, resulting in the retention of the image.
Ÿ  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?| Ÿ  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.y y LED can be lighted with Set OSD Menu.
• Menu – General – Power LED – On

NOTE

• 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 in Control Panel > Display > settings.
• 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.
