Poor Results With ColorMunki Photo On PC
Customers can create a display profile that produces poor results (color cast, low contrast, high contrast, low luminance, etc...).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.
- Consider turning off all anti-virus and/or firewall software when profiling if you are using them.
Please do the following in exactly this order:
First, make the Windows OS settings that are explained in the following web article. Although this was written for Windows 7, everything will apply except for Aero Mode…Windows 8 & 10 dropped that visual theme.

Please try the following:
- Reset your monitor to factory settings using the monitor’s menu if possible.
- Download and save the attached “XRite_LinearProfile.icc” to your desktop. Right-click on the downloaded file and select “Install Profile”.
- In File Explorer, go to: C:\Program Files (x86)\X-Rite\ColorMunki Photo\Tools\Profiles. Right click on “XRite_LinearProfile.icc” and then left click on “Install Profile”. Close File Explorer.
- Select the “DisplayProfile_Linear.icc” profile and click “Set as Default Profile”. If the “DisplayProfile_Linear.icc” profile is not in the list, select “Add…” to select it from a larger list and then set it as the default.
Profile your display while turning off “ADC” and not using the video LUTs to adjust brightness by opening the ColorMunki Photo “Preferences” window with the ColorMunki plugged in. Follow these instructions to turn these functions off:
- On PC…go to “File” and click on “Preferences”.
- Uncheck “Achieve display luminance value using video LUTs” and uncheck “Enable ADC”. Click “OK” to save these settings and close the “Preferences” window.
- Select “Profile My Display”.
- When profiling, select the “Advanced” method and use D65 for the white point and select the bottom radio button to choose a target luminance of 120 cd/m2.
- Make sure that the shutter is open on the bottom of the zippered pouch and the optics (small glass bulb roughly ¾ inch inside the Munki) is visible thru the open shutter when the rotary dial is pointed to the down (measure) position.
- When saving the profile, use a unique name. CM Photo 1.2.2 will insert a date/time stamp to make it unique. The profile name MUST end with “.icm”.
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 ColorMunki’s Preference menu found in “File” > “Preferences” from the home screen. We would recommend using the Advanced method and select the bottom option to set luminance to a specific level and then select “120”. If your prints are darker than your display, feel free to try a lower display luminance setting of 100, 90, or even 80.
