DisplayCAL 3.1.5 released

Added in this release:

  • HDR: Allow specifying of black output offset for SMPTE 2084.

Changed in this release:

  • HDR: Implemented SMPTE 2084 rolloff according to ITU-R BT.2390.
  • HDR: Implemented SMPTE 2084 3D LUT tone mapping (preserve hue and saturation with rolloff).
  • HDR: Improved SMPTE 2084 3D LUT perceptual intent rendering (better preserve saturation). Note that colorimetric intent is recommended and will also do tone mapping.
  • Linux/colord: Increase timeout when querying for newly installed profiles to 20 seconnds.

Fixed in this release:

  • Minor: HDR peak luminance textbox was sometimes not able to receive focus.
  • Minor (Mac OS X): Don’t omit ICC files from compressed archives (regression of adding device link profiles as possible 3D LUT output format in DisplayCAL 3.1.3).

Enjoy!

DisplayCAL 3.1.4 released

Added in this release:

  • A fourth Rec. 709 encompassing color space variant as a profile connection space candidate for XYZ LUT profiles. May lead to better utilization of PCS-to-device color lookup table grid points in some cases (and thus potentially smaller profiles when the effective resolution is set to the default of “Auto”).
  • An option to include legacy serial ports (if any) in detected instruments.
  • SMPTE 2084 (HDR) as 3D LUT tone curve choice.

Changed in this release:

  • Don’t preserve shaper curves in ICC device link profiles if selected as 3D LUT output format (effectively matching other 3D LUT formats).
  • Removed “Prepress” preset due to large overlap with “Softproof”.
  • Changed “Softproof” preset to use 5800K whitepoint target (in line with Fogra softproof handbook typical photography workflow suggested starting point value) and automatic black point hue correction.
  • Synthetic ICC profile creator: Changed SMPTE 2084 to always clip (optionally with roll-off) if peak white is below 10000 cd/m².
  • Synthetic ICC profile creator: Changed transition to specified black point of generated profiles to be consistent with BT.1886 black point blending (less gradual transition, blend over to specified black point considerably closer to black).
  • Profile loader (Windows): If no profile assigned, load implicit linear calibration.

Fixed in this release:

  • When loading settings from an existing profile, some CIECAM02 advanced profiling options were not recognized correctly.
  • Don’t accidentally remove the current display profile if Argyll CMS is older than version 1.1 or the Argyll CMS version is not included in the first line of output due to interference with QuickKeys under Mac OS X.
  • Make sure the Argyll CMS version is detected even if it isn’t contained in the first line of output (fixes Argyll CMS version not being detected if QuickKeys Input Manager is installed under Mac OS X).
  • When loading settings, add 3D LUT input profile to selector if not yet present.
  • Curve viewer/profile information: Fix potential division by zero error when graphing unusual curves (e.g. non-monotonic or with very harsh bends).
  • Profile information: Reset right pane row background color on each profile load (fixes “named color” profile color swatches sticking even after loading a different profile).

Enjoy!

DisplayCAL 3.1.3.1 released

This is a quick update for 3.1.3 that fixes a few minor quirks.

Changed in this release:

  • Updated traditional chinese localization (work-in-progress, thanks to 楊添明).
  • Windows: If madTPG is set to fullscreen and there’s more than one display connected, don’t temporarily override fullscreen if interactive display adjustment is enabled.

Fixed in this release:

  • Windows: If interactive display adjustment is disabled and madTPG is set to fullscreen, show instrument placement countdown messages in madTPG OSD.
  • Windows: Restore madTPG fullscreen button state on disconnect if it was temporarily overridden.
  • Profile loader (Windows): Error message when right-clicking the profile loader task tray icon while DisplayCAL is running.

Fixed 0install Setup (Windows)

Due to changes in Zero Install itself, the DisplayCAL-0install-Setup.exe failed when trying to run Zero Install Setup. If you encountered this problem, please re-download the current DisplayCAL-0install-Setup.exe, which should fix the issue.

DisplayCAL 3.1.3 released

This is a maintenance release for 3.1.

Added in this release:

  • Device link profile as possible 3D LUT output format.
  • French ReadMe (thanks to Jean-Luc Coulon).
  • Partial traditional chinese localization (work-in-progress, thanks to 楊添明).
  • When you change the language in DisplayCAL, the Windows Profile Loader will follow on-the-fly if running.
  • Synthetic ICC profile creator: Capability to specify profile class, technology and colorimetric image state.
  • Windows: When the display configuration is changed while DisplayCAL is running, automatically re-enumerate displays, and load calibration if using the profile loader.
  • Profile loader (Windows): Starting the loader with the --oneshot argument will make it exit after launching.

Changed in this release:

  • Updated ReShade 3D LUT installation instructions in the ReadMe.
  • Improved “Enhance effective resolution of PCS to device tables” smoothing accuracy slightly.
  • Profile loader (Windows):
    • Detect CPKeeper (Color Profile Keeper) and HCFR.
    • Show any calibration loading errors on startup or display/profile change in a notification popup, and also reflect this with a different icon.

Fixed in this release:

  • Added semicolon (“;”) to disallowed profile name characters.
  • ICC profile objects were leaking memory.
  • Windows: Made sure that the virtual console size is not larger than the maximum allowed size (fixes possible inability to launch Argyll CMS tools on some systems if the Windows scaling factor was equal to or above 175%).
  • Windows (Vista and newer): Use system-wide profiles if per-user profiles are disabled.
  • Profile loader (Windows):
    • If Windows calibration management is enabled (not recommended!), correctly reflect the disabled state of the profile loader in the task tray icon and don’t load calibration when launching the profile loader (but keep track of profile assignment changes).
    • Prevent a race condition when “Fix profile associations automatically” is enabled and changing the display configuration, which could lead to wrong profile associations not being fixed.
    • Sometimes the loader did not exit cleanly if using taskkill or similar external methods.
    • Prevent a race condition where the loader could try to access a no longer available display device right after a display configuration change, which resulted in no longer being able to influence the calibration state (requiring a loader restart to fix).
    • Profile loader not reacting to display changes under Windows XP.

Enjoy!

DisplayCAL 3.1.1 released

This is a bugfix/maintenance release for 3.1.

If you update from DisplayCAL 3.1 standalone under Windows using the installer, please close the profile loader manually (if it is running) before running setup – due to an unfortunate bug, the installer may not be able to close and restart the profile loader automatically, which may then require using the task manager to end the profile loader process. Apologies for the inconvenience.

Added in this release:

  • Profile loader (Windows): Right-click menu items to open Windows color management and display settings.

Changed in this release:

  • Profile loader (Windows):
    • Detect f.lux and dispcal/dispread when running outside DisplayCAL.
    • Don’t notify on launch or when detecting DisplayCAL or madVR.
    • Detect madVR through window enumeration instead of via madHcNet (so madVR can be updated without having to close and restart the profile loader).
    • Enforce calibration state periodically regardless of video card gamma table state.
    • Don’t use Windows native notifications to overcome their limitations (maximum number of lines, text wrapping).
    • Show profile associations and video card gamma table state in notification popup.

Fixed in this release:

  • Error after measurements when doing verification with “Untethered” selected as display device and using a simulation profile (not as target).
  • Windows: Sporadic application errors on logout/reboot/shutdown on some systems when DisplayCAL or one of the other applications was still running.
  • Standalone installer (Windows): Remove dispcalGUI program group entries on upgrade.
  • Profile loader (Windows):
    • Error when trying to enable “Fix profile associations automatically” when one or more display devices don’t have a profile assigned.
    • Sporadic errors related to taskbar icon redraw on some systems when showing a notification after changing the display configuration (possibly a wxPython/wxWidgets bug).
  • Mac OS X: Application hang when trying to quit while the testchart editor had unsaved changes.

Enjoy!

DisplayCAL 3.1 released

dispcalGUI has been renamed to DisplayCAL.

If you upgrade using 0install under Linux: It is recommended that you download the respective DisplayCAL-0install package for your distribution and install it so that the applications accessible via the menu of your desktop environment are updated properly.

If you upgrade using 0install under Mac OS X: It is recommended that you delete existing dispcalGUI application icons, then download the DisplayCAL-0install.dmg disk image to get updated applications.

Added in this release:

  • Better HiDPI support. All text should now be crisp on HiDPI displays (with the exception of axis labels on curve and gamut graphs under Mac OS X). Icons will be scaled according to the scaling factor or DPI set in the display settings under Windows, or the respective (font) scaling or DPI system setting under Linux. Icons will be scaled down or up from their 2x version if a matching size is not available. Note that support for crisp icons in HiDPI mode is currently not available in the GTK3 and Mac OS X port of wxPython/wxWidgets. Also note that if you run a multi-monitor configuration, the application is system-DPI aware but not per-monitor-DPI aware, which is a limitation of wxPython/wxWidgets (under Windows, you will need to log out and back in after changing DPI settings for changes to take effect in DisplayCAL).
  • When having created a compressed archive of a profile and related files, it can now also be imported back in via drag’n’drop or the “Load settings…” menu entry and respective button.
  • Argyll CMS can be automatically downloaded and updated.
  • A compressed logs archive can be created from the log window.
  • Windows: New profile loader. It will stay in the taskbar tray and automatically reload calibration if the display configuration changes or if the calibration is lost (although fullscreen Direct3D applications can still override the calibration). It can also automatically fix profile associations when switching from a multi-monitor configuration to a single display and vice versa (only under Vista and later). In addition, the profile loader is madVR-aware and will disable calibration loading if it detects e.g. madTPG or madVR being used by a video player.

Changed in this release:

  • Changed default calibration speed from “Medium” to “Fast”. Typically this cuts calibration time in half, while the accuracy difference is negligible at below 0.2 delta E.
  • Enabled “Enhance effective resolution of PCS to device tables” and smoothing for L*a*b* LUT profiles.

Fixed in this release:

  • In some cases, importing colorimeter corrections from the vendor software CD could fail (falling back to downloading them from the web).
  • Moving the auto testchart patches slider to a value that changed the profile type did not update BPC accordingly (shaper+matrix defaults to BPC on).
  • Minor: Safari/IE messed up positioning of CCT graph vertical axis labels in measurement reports.
  • Minor: When clicking the “Install profile” button while not on the 3D LUT tab, and “Create 3D LUT after profiling” is enabled, don’t create a 3D LUT.
  • Minor: When changing profile type, only change the selected testchart if needed, and default to “Auto” for all profile types.
  • Minor: 1st launch defaults were slightly different from what was intended (testchart should be “Auto”).
  • Minor: Use OS line separator when writing configuration files.
  • Linux: Text and icon sizes should be more consistent accross the application when the system text scaling or DPI has been adjusted (application restart required).
  • Linux: Fall back to use the XrandR display name for colord device IDs if EDID is not available.
  • Linux/Mac OS X: madVR test pattern generator interface was prone to connection failures due to a race condition. Also, verifying a madVR 3D LUT didn’t work.

Enjoy!
