Settings file Here, you can load a preset, or a calibration. Why has a default gamma of 2. Tabs The main user interface is divided into tabs, with each tab containing a sub-set of settings. Apart from those directly connected displays, a few additional options are also available: Web localhost Starts a standalone web server on your machine, which then allows a local or remote web browser to display the color test patches, e.
Prisma The Q, Inc. Resolve Allows you to use the built-in pattern generator of DaVinci Resolve video editing and grading software, which is accessible over the network or on the local machine.
Untethered See untethered display measurements. Choosing a measurement mode Some instruments may support different measurement modes for different types of display devices. Calibration settings Interactive display adjustment Turning this off skips straight to calibration or profiling measurements instead of giving you the opportunity to alter the display's controls first.
You will normally want to keep this checked, to be able to use the controls to get closer to the chosen target characteristics. Observer To see this setting, you need to have an instrument that supports spectral readings i. White point Allows setting the target white point locus to the equivalent of a daylight or black body spectrum of the given temperature in degrees Kelvin, or as chromaticity co-ordinates. Visual whitepoint editor The visual whitepoint editor allows visually adjusting the whitepoint on display devices that lack hardware controls as well as match several displays to one another or a reference.
For table based profiles LUT [7] , it sets the main lookup table size, and hence quality in the resulting profile. White point If your screen has RGB gain, colortemperature or other whitepoint controls, the first step should be adjusting the whitepoint. Look at the bars shown during the measurements to adjust RGB gains and minimize the delta E to the target whitepoint. White level Continue with the white level adjustment. If you have set a target white level, you may reduce or increase the brightness of your screen ideally using only the backlight until the desired value is reached i.
If you haven't set a target, simply adjust the screen to a visually pleasing brightness that doesn't cause eye strain. You may reduce or increase the brightness of your screen until the desired black level is reached i. White point The next step should be adjusting the whitepoint, using the display's RGB gain controls or other means of adjusting the whitepoint. If you have set a target white level, you may reduce or increase contrast until the desired value is reached i.
If you haven't set a target, simply adjust the screen to a visually pleasing level that doesn't cause eye strain. Black point If your display has RGB offset controls, you can adjust the black point as well, in much the same way that you adjusted the whitepoint.
Select one of the pre-baked testcharts to use as base and bring up the testchart editor. It should automatically select the previous profile you've chosen. Then place a check in the checkbox. Make sure adaptation is set to a high level e. Create the chart and save it. Start the profiling measurements e. Profile installation When installing a profile after creating or updating it, a startup item to load its calibration curves automatically on login will be created on Windows and Linux, Mac OS X does not need a loader.
Profile loader Windows Under Windows, the profile loader will stay in the taskbar tray and keep the calibration loaded unless started with the --oneshot argument, which will make the loader exit after loading calibration.
A right-click menu allows you to set the desired calibration state and a few other options: Load calibration from current display device profile s.
Reset video card gamma table. This periodically checks if the video card gamma tables match the desired calibration state. It may take up to three seconds until the selected calibration state is automatically re-applied. Fix profile associations automatically when only one display is active in a multi-display setup. This is a work-around for applications and Windows itself querying the display profile in a way that does not take into account the active display, which can lead to a wrong profile being used.
A pre-requisite for this working correctly is that the profile loader has to be running before you switch from a multi-display to a single-display configuration in Windows, and the profile associations have to be correct at this point.
Note that quitting the profile loader will restore profile associations to what they were honoring any changes to profile associations during its runtime. Also note that profile associations cannot be fixed and the respective option will be disabled in display configurations with three or more displays where some of them are deactivated.
Some graphics drivers may internally quantize the video card gamma table values to a lower bitdepth than the nominal 16 bits per channel that are encoded in the video card gamma table tag of DisplayCAL-generated profiles. If this quantization is done using integer truncating instead of rounding, this may pronounce banding. In that case, you can let the profile loader quantize to the target bitdepth by using rounding, which may produce a smoother result.
You can override the global profile loader state on a per application basis. Profile associations. Brings up a dialog where you can associate profiles to your display devices.
Open Windows display settings. If this box is unchecked, you can create a 3D LUT from an existing profile. Predefined settings are Rec. Black output offset To accomodate a non-zero black level of a real display, the tone response curve needs to be offset and scaled accordingly.
A split between input and output offset is also possible. Target peak luminance only available for SMPTE This allows you to adjust the clipping point when not using roll-off or roll-off to the desired target peak luminance.
A way to do this is to specify the mastering display black and peak luminance levels. This is achieved by taking into account the ambient luminance as per BT. Note that there is usually no need to change this from the default DCI P3 , and that this setting has most impact on non-colorimetric rendering intents. Normally, this should always be enabled if the profile contains a non-linear 1D LUT calibration, otherwise you have to make sure the 1D calibration is loaded whenever the 3D LUT is used.
Out of gamut colors will be clipped to the closest possible match. The destination whitepoint will be altered to match the source whitepoint if possible, which may get clipped if it is out of gamut. The destination whitepoint is not altered to match the source whitepoint. As much as possible, clipping is avoided, hues and the overall appearance is maintained. This intent is useful if the destination gamut is smaller than the source gamut.
The destination whitepoint is altered to match the source whitepoint. No contrast enhancement is used if the dynamic range is reduced.
This intent may be of use where preserving the tonal distinctions in images is more important than maintaining overall colorfulness or contrast. This intent is useful if you have calibrated a display to a custom whitepoint that you want to keep.
Note that in most cases, sensible defaults will be chosen depending on selected 3D LUT format, but may be application- or workflow-specific. Checking the accuracy of a display profile evaluating how well the profile characterizes the display In this case, you want to use a testchart with RGB device values and no simulation profile.
Whitepoint simulation. To explain the latter option: Let's assume a reference has a whitepoint that is slightly blueish compared to D50 , and a display profile has a whitepoint that is more blueish compared to D If you do not choose to simulate the reference white relative to the display profile whitepoint, and the display profile's gamut is large and accurate enough to accomodate the reference white, then that is exactly what you will get.
Depending on the adaptation state of your eyes though, it may be reasonable to assume that you are to a large extent adapted to the display profile whitepoint assuming it is valid for the device , and the simulated whitepoint will look a little yellowish compared to the display profile whitepoint.
In this case, choosing to simulate the whitepoint relative to that of the display profile may give you a better visual match e. Whitepoint simulation does not apply here because color management will not be used and the display device is expected to be in the state described by the simulation profile.
This may be accomplished in several ways, for example the display may be calibrated internally or externally, by a 3D LUT or device link profile. This allows you to check how well the 3D LUT transforms the simulation colorspace to the display colorspace.
Note this setting can not be used together with a DeviceLink profile. DeviceLink profile. This allows you to check how well the DeviceLink transforms the simulation colorspace to the display colorspace. Tone response curve. To check a display that does not have an associated profile e.
How were the nominal and recommended aim values chosen? How are the results of the profile verification report to be interpreted? Keep all that in mind when admiring or pulling your hair out over verification results : How are profiles evaluated against the measured values?
How is a testchart or reference file used? How is the assumed vs. Resolve Untethered display measurements Please note that the untethered mode should generally only be used if you've exhausted all other options.
The procedure is as follows: Select the desired testchart, then open the testchart editor. Burn the images to a DVD, copy them on an USB stick or use any other available means to get them to display onto the device that should be measured. Show the first image on the remote display, and attach the instrument. Choose testchart file Loads a testchart. Edit testchart Choose save path Create profile from measurement data Allows you to re- create a profile from existing measurement data existing profiles created with ArgyllCMS or DisplayCAL can also be selected as source with the current profiling settings.
Create profile from extended display identification data Allows you to create a profile from your display's EDID [10] if available. Install display device profile Install an existing profile for the currently selected display. Upload profile This will only work for profiles created from actual measurements by DisplayCAL 0. Profile information Show gamut plot, calibration and tone response curves, as well as header and tag information for the current profile. Locate ArgyllCMS executables Use fancy progress dialog Use a fancy progress dialog with animations and sound while doing measurements and intense processing.
Show advanced options Enabling this menu option will show some additional controls and menu options for advanced users. You may be able to calibrate one screen, and then share the calibration with another screen. Profiling can be done independently to calibration on each screen. Normally DisplayCAL will automatically detect if separate video card gamma table access is needed and appropriate controls need to be displayed , but you may force it by selecting this menu entry. This is not normally the best way to profile a calibrated display, since the frame buffer may have lower precision than the video card gamma table.
This is the way calibration should be applied if madVR is being used to display the test patches. If this option is checked, DisplayCAL will try to skip this sensor calibration. Note even if this option is checked, you may be forced to do a sensor calibration if the instrument requires it. Useful for debugging. Warning: Very verbose. This allows review of the used command line parameters by checking the log.
Allows you to set additional options for the ArgyllCMS dispcal, dispread, spotread, colprof, collink and targen tools in the same way you would specify them on the commandline. Restore defaults Restores all settings except language, selected display, instrument, measurement mode and profile name to default. Detect displays and instruments To detect changes in display setup or connected instruments, use this menu entry.
Linux: Install udev rules or hotplug scripts that configure instrument access you only need to install these if you cannot access your instrument. The Spyder2 instrument cannot function without the presence of the instrument vendors PLD firmware pattern for the device. The purchaser of a Spyder2 instrument should have received a copy of this firmware along with their instrument from the original vendor, as part of the instrument setup files.
On Microsoft Windows or Mac OS X, if the vendors software has been installed on the users machine, the firmware pattern can usually automatically be located from there. If the vendors software have not been installed, or the user does not wish to install it, or no vendors software are available for the users platform i. In case no firmware files are found, the necessary binary can be downloaded automatically.
You first need to measure the required test colors with a spectrometer, and in case you want to create a correction matrix instead of a spectral correction, also with the colorimeter.
Upload a colorimeter correction to the online Colorimeter Corrections Database to share it with other users or download it later on another machine. This will use the usual input parameters to establish the expected target characteristic. Note that if the initial calibration was modified due to it being out of gamut of the display, verify will show the resulting discrepancy. Measure the display at several points to evaluate evenness of illumination and color errors.
The results are shown after all patches are measured, and include the luminance differences as well as delta E color differences, which are computed in comparison to the reference center point. The evaluation is done according to ISO and , or by comparing the average luminance deviation and delta C, and you can switch between both criteria on-the-fly within the report itself. It's a handy way to get new or changed comparison features, updated layout and even bugfixes into old reports.
A backup copy of the old report with a date extension will automatically be created. Show actual calibration curves from video card When this is enabled in the curve viewer window, it will show the actual calibration curves from the video card gamma table instead of showing the curves of the currently active profile.
Show log window automatically Shows the log window automatically after actions like measurements or creating a profile.
This checks a measurement file for suspicious erroneous readings. An sRGB-like display is assumed, so this option will not work well if the display response is not so close to sRGB, and may report false positives. Non-UI functionality There is a bit of functionality that is not available via the UI and needs to be run from a command prompt or ternminal. Change display profile and calibration whitepoint Note that this reduces the profile gamut and accuracy.
The changed profile will be written to this file. Scripting DisplayCAL supports scripting locally and over the network the latter must be explicitly enabled by setting app. If a modal dialog is displayed, choose the OK option. Note that this is just an example and normally you should be very careful with this, as it could mean confirming a potentially destructive operation e. List of supported commands Below is a list of the currently supported commands the list contains all valid commands for the main application, the standalone tools will typically just support a smaller subset.
If it is minimized, restore it. If a file dialog is shown, using ok filename chooses that file. For non-virtual displays as well as pattern generators except madVR , call the measure command afterwards to commence measurements. Note that this tries to abort any running operations first, so you may want to check application state via the getstate command. Relative paths are possible e. Optionally, load filename. The returned format is classname ID name label state. Return value will be either idle , busy , dialogclassname ID dialogname [dialoglabel] state "messagetext" [path "path"] [buttons "buttonlabel" Most commands will not work if the UI is blocked—the only way to resolve the block is to non-programmatically interact with the actual UI elements of the application or closing it.
Note that a state of blocked should normally only occur if an actual file dialog is shown. If using the scripting interface exclusively, this should never happen because it uses a replacement file dialog that supports the same actions as a real file dialog, but doesn't block. Also note that a return value of blocked for any of the other commands just means that a modal dialog is currently waiting to be interacted with, only if getstate also returns blocked you cannot resolve the situation with scripting alone.
Each returned line represents an UI element and has the format classname ID name ["label"] state [checked] [value "value"] [items "item" It can help you determine what type of UI element it is, and which interactions it supports. ID is a numeric identifier. You can use the latter three with the interact command. There are two sections, ranges and values. Options not covered by ranges and values are limited to their data type you can't set a numeric option to a string and vice versa.
The returned format is a list of classname ID name label state. Otherwise, setup measurement to create the HTML report filename. Call refresh after changing the configuration to update the GUI. The special value null clears a configuration option. Also see getdefaults and getvalid. The default plain is a text format that is easy to read, but not necessarily the best for parsing programmatically.
The other possible formats are json , json. User data and configuration file locations DisplayCAL uses the following folders for configuration, logfiles and storage the storage directory is configurable.
Please rerun your monitor calibration software. If all colormanaged applications you use show swapped colors, you should create a matrix profile instead. USB 3. From all information that is known about these issues, they seem to be related to USB 3. The underlying issue seems to be that while USB 3. Solution: A potential solution to such USB 3. This issue is fixed in ArgyllCMS 1. To disable UAC [9] not recommended!
Click on the Tools tab. Close msconfig. You need to reboot your system for changes to apply. A workaround is to rename, move or disable e. Note that the precision of Windows' built-in calibration loading is inferior compared to the DisplayCAL profile loader and may introduce inaccuracies and artifacts.
MS Windows XP, multiple displays: One profile is used by all displays connected to a graphics card Solution: The underlying issue is that Windows XP assigns color profiles per logical graphics card, not per output. Most XP graphics drivers present only one logical card to the OS even if the card itself has multiple outputs. There are several possible solutions to this problem: Use different graphics cards and connect only one display to each this is probably the preferable solution in terms of ease of use and is least prone to configuration error Install and use the Windows XP color control applet note that the original MS download link is no longer available Some graphics cards, like the Matrox Parhelia APV no longer produced , will expose two logical cards to the OS when using a specific vendor driver some older ATI drivers also had this feature, but it seems to have been removed from newer ones Mac OS X Preview Solution: Due to what appear to be bugs in Mac OS X, applications using ColorSync may show artifacts like black crush and posterization with certain types of display profiles i.
Applications from 3rd parties which use their own color management engine like Adobe products are not affected. Verdict: You don't need to use expensive monitors for photo editing , as the built-in display color calibration tool on Windows 10 offers the most detailed setup instructions. Enter "Color Calibration" in the search bar and select the gamma, brightness, contrast and color balance settings for your display.
A sample image that you can create will accompany many customizations. After the calibration wizard finishes the work, be sure to select the current version of the calibration or return to the previous one if you are not satisfied with the results.
The new calibration will be saved as an. Verdict: QuickGamma is a utility designed to quickly calibrate your monitor without having to buy any hardware tools. The preview section displays the outer and inner stripes with the same gray levels, as well as two black levels, so you can better understand how the changes affect the display.
Red, green, and blue channels can be changed together, or you can press the dedicated Gamma button to control them individually, while tracking the changes using the other displayed preview section.
