The “user entry” feature is helpful for storing non-standard timing
information, or special applications where a preset timing parameter

Quadra performs its timing functions in the following way:

When you connect a display to one of Quadra’s outputs, Quadra
automatically measures the display’s timing parameters.

OUTPUT TIMING
The Output Timing procedure enables you to match a channel’s output signal
to the graphic display device that is attached to that channel. Quadra generates
a wide range of preset VESA-compliant output formats, and also enables users
to define custom values.

If you choose to manually enter timing parameters, the
output timing procedure should be performed first,
followed by the input timing procedure. This sequence
should be repeated for each of Quadra’s four channels.
