yy
Is the power LED on?
Check the power cable connection and press the power button.
yy
Check that the connected input is enabled (Settings > Input > Input
yy
list).
Is the power on and the power LED
displaying white?
Is the OUT OF RANGE message being

This occurs when signals transferred from the PC (graphics card) are out
yy
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
yy
missing or disconnected. Check the cable and reconnect it.

The OSD is locked. Go to Settings > General and set OSD Lock to Off.
yy
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
yy
screen, resulting in the retention of the image.
To extend the lifetime of the monitor, use a screensaver.
yy
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
yy
may be flickering. Change the resolution to 1080P or the recommended
resolution.
NOTE
yy 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.
yy 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.
yy LED can be lighted with Set OSD Menu.
