NOTE
- Vertical frequency: In order to display an image, the screen must be refreshed dozens of times per second like a fluorescent lamp. The number of times the screen is refreshed per second is called vertical frequency or refresh rate and is represented by Hz.
- Horizontal frequency: The time it takes to display one horizontal line is called the horizontal cycle. The number of horizontal lines displayed in one second can be calculated by dividing one by the horizontal cycle. This is called horizontal frequency and is represented by kHz.
NOTE
- Check if the video card’s resolution or frequency is within the range allowed by the monitor and set to the recommended (optimal) resolution in the Control panel > Display > Settings.
- Failing to set the video card to the recommended (optimal) resolution may result in blurred text, a dimmed screen, a truncated display area, or misalignment of the display.
- The configuration procedure may differ depending on your computer and/or operating system. also, some video cards may not support certain resolutions. If this is the case, contact the computer or video card manufacturer for assistance.
- The auTO option is only available for D-SuB (analog) signals.
