Tyco 1939L Computer Monitor User Manual


 
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. If any of these display modes are detected, the
monitor automatically adjusts the picture size and centering. When no mode is matched, the user can
store their preferred modes in the user modes. The monitor is capable of storing up to 7 user modes.
The only condition to store as a user mode is the new display information must have 1 KHz differ-
ence for horizontal frequency or 1 Hz for vertical frequency or the sync signal polarities are differ-
ent from the default modes.
