HDMI Extenders

The input may also be indirectly connected using an HDMI extender. By default, the SW1900-HD
keeps its display information (EDID) local to each input. There is very little delay from the time
an input device asks for the display information to the time the information is sent. A device
connected to an extender may “time-out” waiting for a response from the display device. If a
time-out occurs, the input device will not send its content. It is important to use high quality
extenders so any delay caused by the extender technology is minimized and time-outs are less
likely to occur.
The SW1900-HD has a “pass through” mode that passes all display information requests directly
to the display. If this feature is enabled and the system is configured with extenders on the input
and output ports of the SW1900-HD it is possible to have time-outs on certain input devices.
