Smart Edid Management - Hall Technologies SP-HD-4C User Manual

Smart EDID Management

When the unit powers up or when it first detects that a video source is connected the device, it creates
an EDID for the source based on the first display found scanned from #1 to #4, in order.
If you have a mix of 4K and 1080p displays, make sure to connect the 4K display to output #1. That way
the EDID generated for the source will have 4K native causing the source to output a 4K image. Then
for the displays that do not support 4K, set the max resolution Dip Switch on the front panel to 1080p
(see next section).
If no displays are connected, the splitter uses an internal "default" Hall Research EDID so the HDMI
source will always send a signal. This internal EDID will be used until an external display is connected to
one of the output ports.
Once an external EDID is found, it is retained until power is cycled, even if the output display is
exchanged for another.
The SP-HD-4C maintains the audio extraction feature even if there are no active displays connected to
the outputs.
*Note: Only use the regulated 12 vDC supply (center positive) supplied with the unit. Never substitute
any other power supply as this can destroy the unit.
