Download DisplayCAL 3.8.7.1

DisplayCAL is an open source program aimed at the color calibration of a monitor or projector. It uses ArgyllCMS in the background and can work with different calibration devices work together to achieve a natural color rendering. This is mainly used in cases where color fidelity is important, such as photographers who post-process photos on a computer or when preparing color printing. The developer has released DisplayCAL 3.8.7.1 with the following changes:

DisplayCAL 3.8.7.1 released

Fixed in this release:

• Profile information (Linux): When using wxPython 3.0 instead of 4.0, clicking the sash would throw an error (using wxPython 3.0 is deprecated).
• macOS: Only automatically re-enable black point compensation if restoring defaults or loading a non-3D-LUT preset.
• Profile loader (Windows): Work-around two instances of the profile loader being started after powering on the system if fast startup was enabled in Windows power settings.

DisplayCAL 3.8.7 released

Changed in this release:

• macOS: Automatically enable not using the video card gamma table to apply calibration during characterization measurements if using limited range (16..235). This should mitigate issues with older graphics chipsets and/or macOS versions that use the wrong output range internally when connected to some monitors that expect to receive limited range signals.
• Profile loader (Windows): A scheduled task now restarts the profile loader after resume from standby/hibernation as well as daily at 04:00 AM (whichever comes first), to mitigate the Windows GDI SetDeviceGammaRamp API leaking memory since Windows 10 1903.

Fixed in this release:

• Don’t automatically disable interactive display adjustment when setting calibration tone curve to “As measured” (unintended behavioral change introduced in DisplayCAL 3.8.6, SVN revision r6194).
• Linux (GNOME on Wayland): Latency incurred by a large measurement window size was not accounted for, introducing the possibility of measurements failing due to loss of synchronization.
• Linux (GNOME on Wayland): Limited range (16..235) support.
• macOS: Get rid of brief profile installation dialog flicker after installation.
