Updating to 10.5.6 has broken DDC/CI monitor communications
Hi,
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?
A New Mac Pro features: one Mini DisplayPort, and one dual-link DVI port.
Using the mini displayport to DVI-D Single Link Connection the computer was unable to properly calibrate the monitor.
Only the dual-link DVI port worked properly.
So my question is what are older imac and macbook users supposed to do given that they only have mini dvi.
Also, how is apple going to tell MacBook Pro users that because they got Mini DisplayPort that they will no longer be able to do pro color correction on a calibrated monitor?
I'm beyond angry. If you include the price of my new 15" MacBook Pro (aluminum unibody) with the $1300 I invested in a new NEC Display, I've just wasted close to $4000.
SpectraView II provides automatic display monitor color calibration and profiling functions for supported models of NEC display monitors.
The software uses a two way communications link with the display monitor via the video graphics adapter and normal video cable. No extra cables are necessary.
This communications link is called DDC/CI (Display Data Channel - Command Interface) and is an industry standard developed by VESA (Video Electronics Standards Association)
Support for the X-Rite iOne Display, iOne Pro, iOne Monitor, DTP94 / MonacoOPTIX-XR, ColorMunki, and Datacolor Spyder2 and Spyder3 color sensors is included and automatically installed with SpectraView.
Release Notes
Known issues:
Mac Pro with Nvidia graphics card and dual monitors may not detect monitors correctly (versions of Mac OS up to and including OS 10.5.1):
The Mac Pro with Nvidia graphics card may fail to correctly detect the connected monitors if dual monitors are being used. SpectraView may either incorrectly detect no supported display monitors, or detect two identical monitors. This issue has been fixed in Mac OS 10.5.2 and newer.
To workaround this issue, perform the following steps:
1. Disconnect the display monitor connected to the DISPLAY 1 connector on the rear of the Mac Pro.
2. Shutdown the Mac and then power on (do not just restart).
3. After the system has booted, connect the second monitor to the DISPLAY 1 connector.
4. The system will detect the display monitor correctly.
5. If the monitors are disconnected, reconfigured, or replaced, the above procedure may need to be repeated.
X-Rite/GretagMacbeth iOne Pro or iOne Monitor: If using the X-Rite/GretagMacbeth iOne Pro or iOne Monitor -
Be sure to allow the device at least 15 minutes to warm up before calibrating the display.
Measurements may drift slightly causing inaccurate measurements, especially when measuring colors close to black.
Selecting the Average low light measurements option in the SpectraView Preferences is highly recommended when using this device.
Be sure to carefully follow the instructions for zero calibrating the device.
X-Rite ColorMunki:
If the X-Rite ColorMunki software is installed it will prevent SpectraView from accessing the device even if the main application is not currently running. SpectraView will detect if the ColorMunki software is running and give the option of closing it automatically.
To use the ColorMunki software again after SpectraView has closed it, you must manually restart the colormunki service or restart your system.
Monitor Calibration Setting file format change:
The file format of the Monitor Calibration Setting (MCS) and Target files have been changed in order to order to include more detailed calibration information. As a result of this change, files generated by versions of SpectraView prior to v1.1.00 will no longer be readable.
NEC LCD2180WG-LED:
Be sure to allow the display monitor at least 30 minutes to warm up before calibrating the display. Failure to do so may result in a LUMINANCE LIMIT REACHED error being displayed as the monitor reaches operating temperature. If this happens, recalibrate the monitor and if necessary, choose a lower luminance value.
Due to the unique wide color gamut of this display, colorimeter based calibration sensors such as the GretagMacbeth iOne Display V1 and V2 are not able to accurately measure some aspects of the display's color characteristics. It is recommended to select the Factory Measurement option for the Primary Colors Chromaticity Coordinates source option in the SpectraView Preferences.
Calibration:
If calibrating to the DICOM tone response curve, selecting the Calibration Priority: Best greyscale color tracking option in the SpectraView Preferences may result in a slight decrease in the DICOM response curve accuracy. If the greatest possible DICOM curve accuracy is required, please select the Maximize Contrast Ratio option.
NEC LCD2690WUXi, LCD2180WG-LED displays and ColorVision Sypder2 color sensor:
The ColorVision Spyder2 color sensor has been tested with the the NEC LCD2690WUXi, LCD3090WQXi and LCD2180WG-LED displays and found to cause inaccurate measurements when measuring the color primaries. This is due to the wide color gamut aspect of these displays. This may result in an inaccurate calibration and ICC Profiles to be generated. At the moment using this color sensor is not recommended with these displays. The Datacolor Spyder 3 has improved measurement performance for these displays.
NEC LCD4020, LCD4620, LCD5220, LCD6520, M40 and M46:
The accuracy to which the Intensity can be calibrated when a relatively low value target Intensity is used (less than 150 cd/m2) will be lower than normal, which results in a large Delta-E value to be reported. This is due to the very large screen size, high brightness of the display, and the thermal effect of changing the screen brightness. The monitor may take several minutes after calibration to stabilize in Intensity. Selecting a Target Intensity value slightly higher than the desired value can be used to avoid this issue.
Some versions of these models do not support OSD Control Locking.
Direct color calibration is not available when using the HDMI video input on these models. To calibrate the monitor, use the DVI input, then when completed change to the HDMI input and change the GAMMA SELECTION setting to PROGRAMMABLE on the On Screen Display.
"No Communications" error:
Please see the following section for specific compatibility issues that may cause this error.
Make sure that "DDC/CI" is set to "Enabled" on the On Screen Display (if supported).
Calibrating an NEC LCD3090WQXi with a Mac that only has a miniDisplayPort video output (e.g. 13-inch MacBook, and 15-inch and 17-inch MacBook Pros):
It is necessary to use the Apple Mini DisplayPort to Dual-Link DVI Adapter in order to display the native 2560x1600 resolution of this display. However Mac OS does not currently have the necessary support for this adapter in order for SpectraView to communicate with the display for calibration.
A suggested workaround for this issue is to use the Apple Mini DisplayPort to (Single Link) DVI Adapter temporarily to calibrate the display since this adapter does support the necessary communications with the display monitor. Once the display has been calibrated, the adapter can be changed back to the Apple Mini DisplayPort to Dual-Link DVI Adapter in order to use the full native resolution of the display.
Mac OS 10.5.7 or higher is required in order to support the communications with the display using Apple Mini DisplayPort to (Single Link) DVI Adapter on some Macs.
The recommended steps are as follows:
1. Connect the display using the Apple Mini DisplayPort to (Single Link) DVI Adapter. The display will run at a resolution of 1600x1200 or 1920x1200.
2. Run SpectraView and calibrate the display.
3. Connect the display using the Apple Mini DisplayPort to Dual-Link DVI Adapter. The display should now switch to the native 2560x1600 resolution.
Supported Operating Systems and Macs
This version of SpectraView requires Mac OS X version 10.3.9 or higher.
Installing SpectraView requires an account with administrator privileges.
This version of SpectraView is a Universal Binary and supports both PowerPC and Intel based Macs.
The following Apple Macs require Mac OS 10.5.2 or higher in order to use SpectraView. SpectraView not compatible with these Macs using earlier versions of Mac OS due to issues with the video chipsets and drivers:
Intel based Macs using Intel graphics processors:
Intel Mac mini
13" MacBook with Intel GMA X3100 graphics processor
17" iMac with Intel GMA 950 graphics processor
Second generation MacBook Pro 15" and 17" that have NVIDIA GeForce 8600M GT graphics chipsets.
The following models of NEC display monitors are not compatible with SpectraView when using an Apple MacBook Air or MacBook 13" with Intel GMA X3100 graphics processor.
NEC LCD2490WUXi

NEC LCD3090WQXi
NEC LCD4020
NEC LCD4620
NEC LCD5220
NEC LCD6520
NEC Multeos M40
NEC Multeos M46
This issue is due to a hardware incompatibility with the Intel GMA X3100 graphics processor and can not be fixed by a future software update. Note that these monitors will otherwise function normally on these models of Apple Macs.
Mac OS 10.5.6 prevents SpectraView from being able to communicate with the display monitor on PPC based Macs and some Intel based Macs. Customers should update to Mac OS 10.5.7 to avoid this issue.
If upgrading to Mac OS 10.5.7 does not fix this issue, and you are using an Nvidia video card, please contact NEC Technical Support directly for assistance.
The 13-inch MacBook, and 15-inch and 17-inch MacBook Pros with Mini DisplayPort video outputs released by Apple in October 2008 and January 2009 require Mac OS 10.5.7 in order to work with SpectraView using the DisplayPort to SingleLink DVI adapter from Apple. SpectraView will not be able to calibrate NEC monitors when using Mac OS 10.5.6 and earlier on these machines.
The DisplayPort to DualLink DVI adapter required to run the LCD3090WQXi at native resolution (2560x1600) is not yet compatible with SpectraView. It is recommended to use the DisplayPort to SingleLink DVI adapter from Apple to calibrate the display, then switch back to the DisplayPort to DualLink DVI adapter in order to use the native resolution of the display.
