PRESET MODES
To reduce the need for adjustment for different modes, the monitor has default setting
modes that are most commonly used as given in the table below. For optimum adjustment,
the user is suggested to perform the Auto Setup under Windows “Full Screen” pattern or
using the pattern in the floppy disk provided. When none of the mode is matched, the user
can store their preferred modes in the user modes. The monitor is capable of storing up to
9 user modes. The only condition to store as a user mode is the new display information
must have 1 KHz difference for horizontal frequency or 1 Hz for vertical frequency or the
sync signal polarities are different from the default modes.
