DisplayCAL 3.2.4 released

Added in this release:

  • Korean translation thanks to 김환(Howard Kim).

Changed in this release:

  • Disable observer selection if observer is set by a colorimeter correction.
  • 3D LUT maker: Enable black output offset choice for 16-bit table-based source profiles.
  • Profile loader (Windows): “Automatically fix profile associations” is now enabled by default.
  • Build system: Filter out “build”, “dist” as well as entries starting with a dot (“.”) to speed up traversing the source directory tree (distutils/setuptools hack).

Fixed in this release:

  • Could not create colorimeter correction from existing measurements for instruments that don’t support alternative standard observers.
  • ColorHug / ColorHug2 “Auto” measurement mode threw an error if the extended display identification data did not contain a model name.
  • [Trivial/cosmetic] Testchart editor: When adding reference patches, resize row labels if needed.
  • Profile loader (Linux): When errors occured during calibration loading, there was no longer any message popup.
  • Profile loader (Windows): Filter non-existing profiles (e.g. ones that have been deleted via Windows Explorer without first disassociating them from the display device) from the list of associated profiles (same behavior as Windows color management settings).
  • Profile loader (Windows): When changing the language on-the-fly via DisplayCAL, update primary display device identfier string.

DisplayCAL 3.2.3 released

This is a bugfix and maintenance release.

Changed in this release:

  • Updated traditional chinese translation (thanks to 楊添明).
  • Profile loader (Windows): When creating the profile loader launcher task, set it to stop existing instance of the task when launching to circumvent a possible Windows bug where a task would not start even if no previous instance was running.

Fixed in this release:

  • When querying the online colorimeter corrections database for matching corrections, only query for corrections with a matching manufacturer ID in addition to a matching display model name (fixes corrections being offered for displays from different manufacturers, but matching model names).
  • Profile loader (Windows): Fix unhandled exception if no profile is assigned to a display (regression of a change to show the profile description instead of just the file name in DisplayCAL 3.2.1).

Happy new year everyone!

DisplayCAL 3.2.2 released

This is a bugfix and maintenance release.

Changed in this release:

  • Importing colorimeter corrections from other display profiling software now only imports from the explicitly selected entries in automatic mode.
  • Profile loader launcher (Windows): Pass through --oneshot argument to profile loader.

Fixed in this release:

  • Visual whitepoint editor: Opening a second editor on the same display without first dragging the previously opened editor to another display would overwrite the cached profile association for the current display with the visual whitepoint editor temporary profile, thus preventing the correct profile association being restored when the editor was closed.
  • Mac OS X: Fall back to HTTP when downloading X3D viewer components to work around broken Python TLS support.
  • Windows: When installing instrument drivers, catch WMI errors while trying to query device hardware IDs for instruments.
  • Profile loader (Windows): Possibility of unhandled exception when resuming from sleep if the graphics chipset is an Intel integrated HD graphics with more than one attached display device (may affect other graphics chipsets as well).

DisplayCAL 3.2.1 released

This is a bugfix and maintenance release.

Changed in this release:

  • Profile loader (Windows Vista and later): The profile loader process now auto-starts with the highest available privileges if installed as administrator. This allows changing system default profile associations whenever logged in with administrative privileges.
  • Profile loader (Windows Vista and later): If running under a restricted user account and using system defaults, clicking any of the “Add…”, “Remove” and “Set as default” buttons will allow to restart the profile loader with elevated privileges.
  • Profile loader (Windows): Show profile description in addition to profile file name in profile associations dialog.

Fixed in this release:

  • Linux, Windows: Visual whitepoint editor was not working in HiDPI mode.
  • Windows: Irritating “File not found” error after installing a profile with special characters in the profile name (note that the profile was installed regardless).
  • [Cosmetic] Standalone executables (Windows): In HiDPI mode, taskbar and task switcher icons could be showing placeholders due to missing icon files.
  • [Minor] Profile loader (Windows): Enable the profile associations dialog “Add…” button irrespective of the current list of profiles being empty.
  • [Minor] Profile loader (Windows): Suppress error message when trying to remove a profile from the active display device if the profile is the system default for said device (and thus cannot be removed unless running as administrator) but not for the current one.
  • Profile loader (Windows): Do not fail to close profile information windows if the profile associations dialog has already been closed.
  • Profile loader (Windows): If logging into another user account with different DPI settings while keeping the original session running, then logging out of the other account and returning to the original session, the profile loader could deadlock.

DisplayCAL 3.2 released

I’m happy to announce that DisplayCAL 3.2 has been released. This is a major update.

Added in this release:

  • Visual whitepoint editor. This allows visually adjusting the whitepoint on display devices that lack hardware controls as well as match several displays to one another (or a reference). To use it, set the whitepoint to “Chromaticity” on the “Calibration” tab and click the visual whitepoint editor button (you can open as many visual whitepoint editors simultaneously as you like, so that e.g. one can be left unchanged as reference, while the other can be adjusted to match said reference). The editor window can be put into a distraction-free fullscreen mode by maximizing it (press ESC to leave fullscreen again). Adjust the whitepoint using the controls on the editor tool pane until you have achieved a visual match. Then, place your instrument on the measurement area and click “Measure”. The measured whitepoint will be set as calibration target.
  • Another “Auto” testchart slider step with 154 patches (equal to small testchart for LUT profiles) for XYZ LUT + matrix profile type.

Changed in this release:

  • Menu overhaul. Menus are now better organized using categorized sub-menus and some menu items have been moved to more appropriate locations:
    • The “Options” menu no longer contains any functionality besides actual options. Advanced options have been moved to a sub-menu.
    • Profile creation from existing measurement files or EDID, profile installation as well as profile upload (sharing) functionality can now be found in the “File” menu.
    • Most functionality available in the “Tools” menu has been grouped into categorized sub-menus, with some of the less-used functionality now available under a separate “Advanced” sub-menu.
    • Measuring the selected testchart, enhancing the effective resolution of a colorimetric PCS-to-device table, loading calibration and resetting the video card gamma tables, detecting displays & instruments, as well as user-initiated spectrometer self-calibration functionality has been moved to the “Tools” menu and respective sub-menus where applicable.
  • Changed default curves + matrix profile testchart as well as first “Auto” testchart slider step back to pre-3.1.7 chart with 73 patches.
  • Better curves + matrix profiles as well as faster computation of XYZ LUT + matrix profiles. The matrix and shaper curves of gamma + matrix, curves + matrix as well as XYZ LUT + matrix profiles are now generated in separate steps which improves the shape and grayscale neutrality of the curves on less well-behaved displays. XYZ LUT + matrix profiles will compute faster, because the curves and matrix are created from a sub-set of the profiling patches, and take around the same time as XYZ LUT + swapped matrix profiles, resulting in a typical overall computation speed increase of around +33% (+100% if just looking at the time needed when not creating PCS-to-device tables) for a XYZ LUT + matrix profile computed from 1148 patches. XYZ LUT + matrix profiles computed from more patches should see a larger computation speed increase of up to +100% depending on patch count.
  • Resolve pattern generator and non-native madVR network implementation: Determine the computer’s local network IP address in a way that is hopefully more reliable across platforms.
  • Profile loader (Windows): Detect and work-around buggy Intel video drivers which, despite reverting to linear gamma tables at certain points (e.g. UAC prompts), will effectively ignore attempts to restore the gamma table calibration if it is considered to be already loaded by the driver.
  • Profile loader (Windows): Replaced “Open Windows color management settings…” pop-up menu item with own “Profile associations…” implementation. This should work better with multi-display configurations in contrast to Windows’ braindead built-in counterpart, i.e. display devices will be listed under their EDID name (if available) as well as their viewport position and size on the virtual desktop and not only their often meaningless generic driver name like “PnP-Monitor”. Also, there won’t be multiple entries for the same display device or ambiguous “1|2” identifications if there are display devices that are currently not part of the desktop due to being disabled in Windows display settings. Changing profile associations around is of course still using Windows color management functionality, but the custom UI will look and act more sane than what Windows color management settings has to offer.
  • Profile loader (Windows): Clicking the task bar tray icon will now always show up-to-date (at the time of clicking) information in the notification popup even if the profile loader is disabled.
  • Profile loader (Windows): Starting a new instance of the profile loader will now always attempt to close an already running instance instead of just notifying it, allowing for easy re-starting.
  • Windows (Vista and later): Installing a profile as system default will now automatically turn off “Use my settings for this device” for the current user, so that if the system default profile is changed by another user, the change is propagated to all users that have opted to use the system default profile (which is the whole point of installing a profile as system default).

Fixed in this release:

  • Spectrometer self-calibration using an i1 Pro or i1 Pro 2 with Argyll >= 1.9 always presented the emissive dark calibration dialog irrespective of measurement mode (but still correctly did a reflective calibration if the measurement mode was one of the high resolution spectrum modes).
  • User-initiated spectrometer self-calibration was not performed if “Allow skipping of spectrometer self-calibration” was enabled in the “Options” menu and the most recent self-calibration was still fresh.
  • Cosmetic: If an update check, colorimeter correction query or profile sharing upload returned a HTTP status code equal to or greater than 400 (server-side error), an unhandled exception was raised instead of presenting a nicer, formatted error dialog (regression of DisplayCAL 3.1.7 instrument driver installer download related changes).
  • Profile loader (Windows, cosmetic): Reflect changed display resolution and position in UI (doesn’t influence functionality).
  • Resolve pattern generator: Unhandled exception if the system hostname could not be resolved to an IP address.

Enjoy!

DisplayCAL 0install Setup (Windows) breakage fix

The code-signed DisplayCAL-0install-Setup executables released on October 21, 2016 and available until October 24, 2016 15:25 (CEST) had a problem with mismatching feed URLs (due to the unintended use of HTTPS) and thus breaking the install. If you downloaded one of these affected setup executables, please uninstall and re-download.

File sizes and MD5 checksums of the new, fixed setup executables:

File name File size MD5
DisplayCAL-0install-Setup.exe 1.551.304 Bytes 08B2F73EB35390B4A1778441719F8194
DisplayCAL-0install-Setup-per-user.exe 974.024 Bytes DB650541D28F0AEFCDEB37673B5C2B8B

DisplayCAL 3.1.7.2 (Windows) has been released

Changed in this release:

  • Windows: Toggling the “Load calibration on login” checkbox in the profile installation dialog now also toggles preserving calibration state in the profile loader and vice versa, thus actually affecting if calibration is loaded on login or not (this restores functionality that was lost with the initial DisplayCAL 3.1 release).
  • Windows: The application, setup and Argyll USB driver installer executables are now digitally signed (starting from October 18, 2016 with SHA-1 digest for 3.1.7.1 and dual SHA-1 and SHA-256 digests for 3.1.7.2 from October 21, 2016).

Fixed in this release:

  • Profile loader (Windows): User-defined exceptions could be lost if exiting the profile loader followed by (re-)loading settings or restoring defaults in DisplayCAL.

Enjoy!

DisplayCAL 3.1.7 released

This release features much easier Argyll CMS instrument driver installation under Windows – no need to (temporarily) disable driver signature enforcement for Windows 8/8.1/10 anymore. Furthermore, the Windows profile loader now offers a way to define exceptions. Also included in this release are minor changes as well as fixes.

See the full changelog at https://displaycal.net/#changelog-3.1.7 for details.

Enjoy!
