Sony GDM-2038 - Manual (Page 10)

Preset Mode
The GDM-2038 adjusts automatically the display size and position to the optimum in
accordance with the input signals of up to 24 different types.
It has factory-preset setting values for 9 different types of signals. When a
computer or a work station that issues such signal is connected, the optimum display
is obtained without any manual adjustment (preset mode).
The factory-preset values and corresponding computer/work station models (called
“preset-type models” in this manual) are as follows:

The buttons on the front panel allow manual adjustment when a signal from
equipment other than the preset-type models is input. Fifteen different manually
adjusted conditions are stored in memory, and called back when the same signal
is input again so that the optimum display for this signal is obtained automatically.
The type of input video signal is discriminated according to its signal specifications,
such as horizontal frequency or sync polarity. When the signal specifications of the
input signals are almost similar, however, these signals may not be discriminated
as different.
