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. If
the mode in use does not match one of the defaults, 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.
