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!
