Also there are currently (2014-05-20) five instruments (or rather, packages) under the Color Munki brand, two of which are spectrometers, and three are colorimeters (not all of them being recent offerings, but you should be able to find them used in case they are no longer sold new): When using a spectrometer that is supported by the unattended feature (see below), having to take the instrument off the screen to do a sensor self-calibration again after display calibration before starting the measurements for profiling may be avoided if the menu item “Allow skipping of spectrometer self-calibration” under the “Advanced” sub-menu in the “Options” menu is checked (colorimeter measurements are always unattended because they generally do not require a sensor calibration away from the screen, with the exception of the i1 Display 1).
Unattended calibration and profiling currently supports the following spectrometers in addition to most colorimeters: to create the version file so you don't see the update popup at launch.
Please note that if your contribution should be put towards adding a certain feature in Argyll CMS, like support for a specific instrument, it will be more appropriate and efficient to contribute to Argyll CMS only, and directly. Display CAL (formerly known as dispcal GUI) is a display calibration and profiling solution with a focus on accuracy and versatility (in fact, the author is of the honest opinion it may be the most accurate and versatile ICC compatible display profiling solution available anywhere).
If you'd like to measure color on the go, you may also be interested in Argyll PRO Color Meter by Graeme Gill, author of Argyll CMS. At its core it relies on Argyll CMS, an open source color management system, to take measurements, create calibrations and profiles, and for a variety of other advanced color related tasks.
If the pre-compiled extension module that is included in the sources does not work for you (in that case you'll notice that the movable measurement window's size does not closely match the size of the borderless window generated by Argyll CMS during display measurements) or you want to re-build it unconditionally, run You only need to install the Argyll-specific driver if your measurement device is not a Color Munki Display, i1 Display Pro, Huey, Color Hug, specbos, spectraval or K-10 (the latter two may require the FTDI virtual COM port driver instead).
To automatically install the Argyll-specific driver that is needed to use some instruments, launch Display CAL and select “Install Argyll CMS instrument drivers...” from the “Tools” menu. Refer to your mainboard or firmware manual how to go about this.
For light personal non-commercial use, a one-time contribution may be appropriate.
If you're using Display CAL professionally, an annual or monthly contribution would make a great deal of difference in ensuring that both projects continue to be available. ), but you'd like to give to Argyll CMS directly on your own behalf (visit and scroll down a bit to get to its contribution links), please leave a message on your Display CAL contribution if contributing to both projects.
Method 1: Disable driver signature enforcement temporarily To install the Argyll-specific driver that is needed to use some instruments, launch Windows' Device Manager and locate the instrument in the device list. Right click on the instrument and select “Update Driver Software...”, then choose “Browse my computer for driver software”, “Let me pick from a list of device drivers on my computer”, “Have Disk...”, browse to the Argyll_VX. X\usb folder, open the Argyll file, click OK, and finally confirm the Argyll driver for your instrument from the list.Update Star includes support for many languages such as English, German, French, Italian, Hungarian, Russian and many more.You can choose your language settings from within the program.If you would like to support the development of, technical assistance with, and continued availability of Display CAL and Argyll CMS, please consider a financial contribution.As Display CAL wouldn't be useful without Argyll CMS, all contributions received for Display CAL will be split between both projects.Display CAL is written in Python and uses the 3rd-party packages Num Py, demjson ( toolkit), as well as Python extensions for Windows and the Python WMI module to provide Windows-specific functionality.
