9.2 Input Signal Automatic Detection
The MSD continuously monitors its input signals. If a particular signal has previously been connected to the
MSD’s input, the output signal will be presented in the same format as it was during the most recent session.
If an input signal does not match any signal previously presented to the MSD, only the input timing settings
are automatically negotiated. Other settings are not affected. The output image size and format settings can
be adjusted if required.

[Fig. 9.3] How signals are recognized
The MSD retains data for up to 50 input devices for each input connector. The data is used to determine if a
signal has been presented to that connector previously by a particular device. The input signal have been
input before or not. If input data storage exceeds 50 memory locations, the oldest data that have not been
input recently will be deleted, instead.
