EDID Control
EDID (Extended Display Identification Data) is a data structure that is used between a display and a source. This data
is used by the source to find out what audio and video resolutions are supported by the display. By pre-determining
the video resolution and audio format of the source and display device you can reduce the time needed for EDID hand
shaking thus making switching quicker and more reliable.
Configuration of the EDID settings for each input can be achieved either via DIP switches on the rear of the matrix or by
using the micro-USB connector and Blustream EDID API commands.

Smart Scale Control
The SP18CS has a smart scale feature on each output allowing a display only capable of supporting lower video
resolutions (4K 60Hz 4:2:0 or 1080p) to receive 4K 60Hz 4:4:4 video content while still showing maximum original 4K
UHD resolution on remaining video outputs.
The SP18CS default smart scale mode is AUTO which will automatically negotiate the best output resolution suitable
for the connected display. If the scaler mode is set to bypass the video output will match the source input signal.
The SP18CS has the ability to force the down-scaling to output 1080p on all outputs which replaces the BYPASS scaling
option. To change the scaling mode either change the mode via API command or aer power cycle complete the
following sequence of changes to dip switch ‘1’
0000 > 1000 > 0000 > 1000 > 0000 > 1000 > 0000
When the smart scale dipswitch is ‘DOWN’ the video output will now be fixed to 1080p
