Specifications

• 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.

Therefore, a resolution other than the specied resolution may degrade the picture quality. To avoid this, it is recommended that you

select the optimum resolution specied for the screen size of your product.

• Check the frequency when you exchange a CDT monitor (connected to a PC) for an LED monitor. If the LED monitor does not support

85Hz, change the vertical frequency to 60Hz using the CDT monitor before you exchange it with the LED monitor.

If a signal that belongs to the following standard signal modes is transmitted from your PC, the screen will automatically be adjusted. If

the signal transmitted from the PC does not belong to the standard signal modes, the screen may be blank even though the power LED

turns 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

Repeating the same picture dozens of times per second allows you to view natural pictures. The repeat frequency is called “vertical

frequency” or “refresh rate” and is indicated in Hz.
