Updating to 10.5.6 has broken DDC/CI monitor communications
this is my first posting.
I have several systems running 10.5.5 and in conjunction with ddc/ci compliant monitors from Lacie, NEC and Samsung. All with their respective monitor calibration software.
Ive updated all machines to 10.5.6. Intel and PPC boxes. All the PPC boxes no longer communicate with their respective calibration software applcations once this update has been installed. The ddc/ci handshake is no failing to initialize in all these packages.
It looks like apple has broken something in the video driver communication at a low level.
This is a rather large problem to those of us relying on color management.
any comment on an update?
thanks.
PPC boxes, Mac OS X (10.5.6)
