DisplayCAL 3.7 released

Added in this release:

  • [Feature] Full field pattern insertion option for selected pattern generators (madTPG*, Prisma and Resolve).
    *madTPG on Windows requires using a modified version of ArgyllCMS.
  • [Feature] Chromatic adaptation control for the synthetic ICC profile creator.
  • Resolve HDR 3D LUT preset (SMPTE 2084 hard clip, no tonemapping).

Changed in this release:

  • [Enhancement] Show a column with the spectral resolution and range of the reference measurements when listing colorimeter corrections from the online database (if available).
  • [Enhancement] Improved support for (3rd party) profiles with chromatic adaptation transforms other than Bradford, e.g. for use as 3D LUT source profiles.
  • [Enhancement] Early abort when cancelling video level detection measurements.
  • [Enhancement] Early abort if connecting to madTPG fails.
  • [Enhancement] Updated simplified chinese translation (thanks to Mars).
  • [Enhancement] If using madTPG and continuing from interactive adjustment to iterative grayscale calibration, wait three seconds after switching to fullscreen and exclusive fullscreen respectively, to give the display time to complete the switch, before commencing measurements.
  • [Enhancement] Show messages from instrument related popup dialogs during measurements on the madTPG on-screen display as well.
  • Hue preservation less than 100% for HDR SMPTE 2084 3D LUTs with roll-off tonemapping now only affects red-orange/orange/amber hues (i.e. match madVR’s “color tweaks for fire & explosions”).
  • [Enhancement] Verification: Before attempting to create a measurement report, automatically check the PCS to device table resolution for LUT profiles if necessary and warn about low resolution tables.
  • [Enhancement] 3D LUT verification: When using a different whitepoint target for a 3D LUT, use the altered source profile as simulation profile for verification.
  • [Enhancement] 3D LUT verification: When creating a self check report, automatically use the device link profile.
  • [Enhancement] Measurement report: Show weighted ΔL, ΔC and ΔH for ΔE*94 and ΔE*00.
  • [Enhancement] Measurement report: Signed values for ΔL*76, ΔL*94, ΔC*76 and ΔC*94 are now always relative to the nominal values (match ΔE*00 and ΔICtCp).
  • [Enhancement] Measurement report: Measured vs display profile whitepoint is now a purely informational statistic, no longer a pass criteria.
  • [UI] When creating a colorimeter correction, allow selecting a display manufacturer via autocomplete if not set.
  • [UI] [Cosmetic] Minor UI spacing adjustments.
  • [Cosmetic] For HDR 3D LUTs with SMPTE 2084 (hard clip) tone curve, set the mastering display peak luminance in the simulation profile description to the target peak.
  • [Enhancement] macOS: For iMacs, use the model identifier as display description.

Fixed in this release:

  • [Minor] Interpolation between clipping and roll-off for HDR 3D LUTs with SMPTE 2084 tone curve was not as smooth as intended with mastering display peak luminance below 10000 cd/m² or just above target peak.
  • [Minor] HDR 3D LUTs with SMPTE 2084 (hard clip) tone curve did reproduce slightly too low luminance in a limited region below the chosen target peak.
  • [Minor] Verification controls were not being initialized if loading settings before switching to the verification tab.
  • [Trivial] Also update verification tone curve controls if a matrix profile with non-identical shaper curves is selected as simulation profile.
  • [Trivial] Make eeColor to madVR converter exit cleanly when receiving SIGBREAK.
  • [Trivial] Correctly escape/unescape quotes in CGATS.
  • [Trivial] Reset enumerated measurement modes when changing Argyll version.
  • [Trivial] Do not automatically disable interactive display adjustment after visual whitepoint editor measurement.
  • [Trivial] When using madTPG, restore fullscreen and OSD button states when continuing on to calibration after interactive adjustment.
  • [Trivial] madTPG did not automatically enter fullscreen if enabled when skipping interactive display adjustment and detecting video levels.
  • [Trivial] Only show the place instrument on screen countdown in madTPG if we don’t temporarily leave fullscreen for interactive adjustment during calibration anyway.
  • [Trivial] Always force HDR 3D LUT SMPTE 2084 mastering display peak luminance to be greater than or equal to target peak luminance.
  • [Cosmetic] Do not show HDR 3D LUT tone mapping hue/saturation controls for SMPTE 2084 (hard clip).
  • [Minor] Measurement report: Measured vs assumed/profile whitepoint delta ICtCp should always be referenced to assumed/profile whitepoint.
  • [Minor] Measurement report: Using absolute values without display profile whitepoint as reference in ICtCp mode referenced the values to D50 instead of the natural ICtCp whitepoint of D65.
  • [Cosmetic] Measurement report: RGB color comparison swatches when using absolute values and display profile whitepoint as reference were not referenced to chosen whitepoint.
  • [Trivial] Profile information: Whitepoint delta E to locus should always be referenced to locus, not D50.
  • [Cosmetic] Profile information: Use correct axis labels for DIN99b 2D gamut plot.
  • [Minor] Standalone 3D LUT maker: Unmatched Thaw() call when setting abstract profile.
  • [Minor] Linux: Prevent potential subprocess memory leak.
  • [Minor] Linux, macOS: When connecting to madTPG, don’t send ‘bye’ commands when closing duplicate connections so madTPG doesn’t close the main connection prematurely.
  • [Trivial] Linux with wxPython Phoenix, Windows: Menu item labels in submenus weren’t updated until restarting the application after switching to a different language.
  • [Trivial] Profile loader (Windows): Use Unicode APIs for creating the popup menu items, so that they are displayed correctly regardless of Windows codepage (makes non-western languages display correctly on western versions of Windows).
  • [Trivial] Windows: Restore compatibility of measurement report with MSIE 11.
  • [Cosmetic] macOS: When creating a colorimeter correction for a MacBook, correctly unescape backslashes in the automatically filled description.
