+Poor Results With i1Display Pro On Mac
If a display profile produces poor results (color cast, low contrast, high contrast, low luminance, etc...), try reprofiling after making sure to check the following:
- Connect the measurement device to a properly powered USB port. Typically, a tower will have rear ports that more reliably and consistently deliver the required power to the device.
- Avoid using USB ports on keyboards and monitors. Also avoid unpowered USB hubs as well as USB extensions.
- An acceptable extension is the use of a powered USB hub. Some laptop computers will require a powered USB hub to deliver the necessary power.
- PLACE THE MEASUREMENT DEVICE FLUSH ON THE SCREEN WHEN PROFILING! This will more easily be accomplished tipping the display back and carefully place the device on the screen while viewing from the side. An instrument that is not flush on the screen’s surface will result in bad measurement data and then poor results when using the profile. Do not push on the device while measuring as pressure can change color on LCD screens.
- Consider turning off all anti-virus and/or firewall software when profiling.
- Laptops must have the power supply connected when profiling.
- Go to System Preferences > Displays and uncheck “Automatically adjust brightness” if it is available.
If the aforementioned suggestions fail to correct the issue, please do the following in exactly this order:
- Go to the Apple icon in the menu bar > System Preferences > Desktop & Screen Saver. Uncheck the “Translucent menu bar”.
- Go to System Preferences > Accessibility and select the “Display” option on the left. Make sure that the “Enhance Contrast” slider is set all the way to the left at “Normal”.
- Now go to the Applications folder and right-click (or control-click) on the i1Profiler application icon and click on “Show Package Contents”
- Navigate to Contents > MacOS > Profiles and then copy and paste the “XRite_LinearProfile.icc” profile to the Mac HD\Library\ColorSync\Profiles folder. Close Finder.
- Open “Displays” in System Preferences and select the “Color” tab. Click on the profile named “DisplayProfile_Linear.icc” to reset your display’s RGB channels to a linear fashion. The onscreen color should change and will likely look bad.
- Close Displays and System Preferences.
- Connect the i1Display Pro and open the i1Profiler software application.
Profile the display using this workflow:
Turn off “ADC” (Automatic Display Calibration) when profiling in the Advanced Mode of i1Profiler. Automatic Display Control (ADC) can sometimes produce unsatisfactory results. Follow these instructions to turn “ADC” off:
- Typically, users should select a white point of “D65”, a luminance setting of “120”, and “Native” for contrast ratio. If you have an Apple monitor manufactured after 2009, select “White LED” for the display technology type.
- In the “Measurement” step, select the “Adjust brightness, contrast, and RGB gains manually”. This will unselect "Automatic Display Control (ADC)"
- Uncheck the contrast and RGB options as those controls are not manually adjustable on an Apple monitor. DO NOT unselect the option to adjust brightness manually…this must remain selected. When adjusting brightness on an Apple display (iMac, MacBook, or Apple displays), you may need to open System Preferences > Displays to fine tune the brightness to more closely match the target.
- Click “Next” to save these settings and begin the profiling process.
- Create a new display profile. When you create and save the profile, save it with a unique name. Perhaps you can add the month and year to the name (i.e., iMac_Feb2014.icc). You will need to retain the “.icc” extension.
The recommended display profiling settings of a D65 white point, 2.2 gamma, and 120cd/m2 has been set by the industry experts. The photographers and graphic designers of the world have determined that a monitor profiled to these parameters will most closely match a print that is viewed in a 5000K light booth (Graphic arts standard). The default gamma (aka; tone response) is set at 2.2 in the Profile Settings step. We recommend using the Advanced method and select a luminance of “120”. If your prints are darker than your display, feel free to try a lower display luminance setting of 100, 90, or even 80.
