3-4 Standard Signal Mode Table The LCD monitor has one optimal resolution for the best visual quality depending on the screen size due to the inherent characteristics of the panel, unlike for a CDT monitor. Therefore, the visual quality will be degraded if the optimal resolution is not set for the panel size. It is recommended setting the resolution to the optimal resolution of the product. If the signal from the PC is one of the following standard signal modes, the screen is set automatically. However, if the signal from the PC is not one of the following signal modes, a blank screen may be displayed or only the Power LED may be turned on. Therefore, configure it as follows referring to the User Manual of the graphics card.

The horizontal frequency is represented in kHz. Vertical Frequency A panel must display the same picture on the screen tens of times every second so that humans can see the picture. This frequency is called the vertical frequency. The vertical frequency is represented in Hz. Using the product 3-4

Horizontal Frequency
The time taken to scan one line from the left-most position to the right-most position on the screen is called the horizontal cycle
and the reciprocal of the horizontal cycle is called the horizontal frequency. The horizontal frequency is represented in kHz.
Vertical Frequency
A panel must display the same picture on the screen tens of times every second so that humans can see the picture. This
frequency is called the vertical frequency. The vertical frequency is represented in Hz.
