SP-HD-4C

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.
6. Per Output Downscaling from 4K to 1080p
If you have a mix of 4K and 1080p TVs, you can still use the splitter and maintain 4K resolution
from the source to all the 4K TVs while downscale the 4K to 1080p so it can be displayed on
the 1080p TVs.
The front panel has a 4 position Dip Switch for downscaling 4K video. Each switch position
corresponds to each output. Make sure to connect your 4K TV to output #1 (so the EDID for
video source uses 4K native), then for each of the TVs that do not support 4K, set the Dip
Switch to 1080p max.
