This product can be set to only one resolution for each screen size to obtain the optimum picture quality due to the nature of the panel. Using a resolution other than
the specified resolution may degrade the picture quality. To avoid this, it is recommended that you select the optimum resolution specified for your product.
Check the frequency when you exchange a CDT product (connected to a PC) for an LCD product. If the LCD product does not support 85Hz, change the vertical
frequency to 60Hz using the CDT product before you exchange it with the LCD product.
The screen will automatically be adjusted if a signal that belongs to the following standard signal modes is transmitted from your PC. If the signal transmitted from the PC
does not belong to the standard signal modes, the screen may be blank with the power LED on. In such a case, change the settings according to the following table by
referring to the graphics card user manual.

Horizontal Frequency
The time required to scan a single line
from the left to the right side of the
screen is called a horizontal cycle. The
reciprocal number of a horizontal cycle
is called horizontal frequency. Horizontal
frequency is measured in kHz.
-
Vertical Frequency
The product displays a single image
multiple times per second (like a
fluorescent light) to display what the
viewer sees. The rate of a single image
being displayed repeatedly per second is
called vertical frequency or refresh rate.
Vertical frequency is measured in Hz.
