Calibrating monitor with Argyll+dispcalGUI

mercredi 15 avril 2015

Argyll+dispcalGUI is free and the results are better

than what you can get from X-rite or Datasoft software...




-Download and install Argyll + dispcalGUI

DispcalGUI have a new “Zero Install”, I do not like and prefer the manual way...

Both versions are available to download.



-I installed argyll to c:/argyll and dispcalGUI to c:/Argyll/dispcalGUI

(better *not* to use version number for directory name)



-For some instruments Argyll driver must be installed, ColorMunki Display/i1 Display Pro do not need,

Huey maybe not, Spyder 3 need and Spyder 4 I do not know.

To install argyll driver into Windows check here.



How Can I Install Hardware with Unsigned Drivers in Windows 8?

-dispcalGUI should run as administrator (Windows vista/7/8)

Click with the right mouse button over C:/Argyll/dispcalGUI/dispcalGUI.exe go to

Properties>Compatibility> and enable “Run this Program as an administrator”





-First time you run dispcalGUI.exe, go to Menu>File>Locate Argyll CMS executables

point to c:/Argyll/bin (remember, I used NO version in directory name)





-Go to menu>Options and enable Show advanced calibration options

set dispcalGUI like this



Calibration Speed deals with the quality of the readings, LOW is the highest setting, but

may take a LOT of time… If everything is right, LOW gives better results.



Click in “Calibrate & profile”

OBS, Single Curve + Matrix profiles may get better neutrals and Curves + Matrix better colors.



A correction matrix is needed for each type of panel back light like

White LED, CCFL, WCCFL, GB-LED and etc... See here.

For Spyder4 or i1Display/Munki go to menu>tools>Import colormeter corrections>AUTO, then select the proper one in the Correction, also can

try to use the ones from dispcalGUI database, just click in the small Earth icon.

(For the AUTO to work, first you must install the default calibration software from Datacolor or X-rite)





-Put the calibration device over the spot and click in "Start measurement"





-Click in “Whitepoint/White level”



Wait 5 seconds and Click in “Start measurement”

Using the monitor RGB channels, try to make 6500 with the smallest delta(all 3 colored bars with the same size) and

adjust the monitor brightness to +- 120 to 160 cd/m2, as I work into a dim environment I prefer 120 cd/m2, when you

have the desired values, click in “Stop measurement” and “Continue on to calibration”

Notebook users probably will not have the option to change the RGB channels, so just adjust the brightness and

change the Whitepoint to Color Temperature 6500K Daylight.





When the process finish, install the profile...





To verify the result, go to menu Tools>Measurement report

For reference, print some targets in Fine Art quality, check http://ift.tt/1OClGdT

The gradient(view in Photoshop) should be smooth with no clipping in the blacks and no color casts.



The gradient with noise is more forgiving...





Consider reading the quickstart http://ift.tt/1OClGe2

Also look at the review sites like http://ift.tt/1FTcKzA

or http://ift.tt/1OClI5C

to see how they calibrated their units for optimum results.
