4.3.6 Failover input

About failover input

This function allows the display to automatically switch to a failover (backup) source in case the main source (DisplayPort, HDMI or SDI 4K) is missing. The display will automatically restore the main source once the signal is back.

The available failover inputs for your display depend on the selected SDI configuration mode. See the following table for more details.

Note: The failover input can only be selected when both

1. the Auto search function is disabled (see “Auto search”), and

2. the PiP/PaP Modes function is disabled (see“Picture and Picture input” and “Picture in Picture input”).

If any of both functions are enabled then failover will be disabled and made unavailable. As soon as both functions are disabled again, failover will be enabled and made available again with the selected failover input.

Note: The failover input will be activated within about 7 seconds after the main source has been lost.
Note: The failover activation time from HDMI 1/2 (main input) to DVI (failover input) is about 8.8 seconds (average time).
Note: During the transition from main to failover input and vice versa, a text message is visible to inform the user.
Note: The main source can be changed while the failover input remains unchanged. During the selection and synchronization of a new main source the failover function is temporary (7 sec) disabled.
Note: (*1) SDI 3 is only available if the SDI configuration is Dual SDI.

(*2) The SDI configuration is Single SDI-1 / Single SDI-3.

(*3) The SDI configuration is Quad-SDI.
