- 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. - 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. - Some resolutions listed in the table above may not be available depending on graphics card specifications.
