• 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 uorescent 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.

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.
