the "Product Specification" section of this manual to set the appropri-
ate frequency.
Is the "CHECK SIGNAL CABLE"

yThis is displayed when the signal cable between the PC and the moni-
tor is missing or disconnected. Check the cable and reconnect.

Is the "OSD LOCKED" message

The screen retains an image.
Does image sticking occur even
when the monitor is turned off?
yDisplaying a still image for a prolonged time may cause damage to the
screen, resulting in the retention of the image.
yUse a screen saver to protect the screen when using the monitor for a
prolonged period of time.
yVertical 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.
yHorizontal frequency: The time it takes to display one horizontal line is called the horizontal cycle.
The number of horizontal lines displayed in one second
can be calculated by dividing one by the horizontal cycle. This is called horizontal frequency and is
represented by kHz.
