3.1 About Fast Switching
Older display devices required a longer time between the loss of one digital signal
and the introduction of another, as well as a physical disconnection of the
interconnecting cable in order to be able to detect and adjust to the new video
attributes and parameters. Normal switching, therefore, introduced a 5V signal
disconnection along with a delay in switching. Many newer display devices,
however, are now capable of “on-the-fly” switching.
Depending on the display device in use, the VS-42HDCP allows for fast switching
(minor reset and the connection kept alive) and extra fast switching (no reset and
the connection kept alive). Using the fast and extra fast switching modes allows for
fraction-of-a-second switching times when using high performance display devices
or when using a scaler on the video output.
