Chapter 7. Appendix

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

Synchronization

Horizontal frequency

30 - 80 kHz

Vertical frequency

60 - 75 Hz

Resolution

Optimum resolution

1920 x 1080 @ 60 Hz

Maximum resolution

1920 x 1080 @ 60 Hz

•  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.

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.
