When sending the EDID setting command, the binary bits in the above table will need
to be converted to their hexadecimal form as sent as two ASCII characters, for
example:
To set the EDID for input 1 to
4K2K@60 (YC444), HDR, 48 bit colour, 7.1ch audio &
3D
the binary bit pattern from the above table would be:
11001001
, which is
C9
in
hexadecimal.
Also,
XX
=
05
for Input 1 and
AA
=
03
for 4K2K@60 (YC444).
The completed EDID command is:
@W 05 03 C9 #
