Python 3.x Development Announcement

[Mark Walter]

Oh you are under Windows. Unfortunately, the development is pretty much concentrated on Linux and partially MacOS for now. And also in future, when we create proper install packages for all OSes, you would not need to tackle with Python at all.

For now, I suggest you to use the DisplayCAL 3.8.9.3 installer for Windows from this site.

Just to let you know what I mean: The measurement button is greyed out and apparently in the windows version it is possible to verify the current icc-profil/display response, even when it is not generated with DisplayCal

Great work Erkan! Looking forward for a macOS install package. Kolay Gelsin.

[Samazar]

Hi Erkan, what is the latest ported version for Mac OS?

[SuspiciousPixel]

Is there no Windows installer for this?

edit – just saw the previous post, guess not yet.

Hi Erkan, try to install requirements in macOS but failed

pip install -r requirements.txt

Forget whet I wrote, it was using system’s python instead of suggested version, I changed this from Erkans tutorial in github
python3.10 -m venv ./displaycal_venv

Running!

[Vincent]

For some reason there are no menus, so I cannot access lots of functionality (it was 1st run)

As somebody said before, you are forces to create profile if you wish to verify it. I was not able run test without creating a profile first (I chose no calibration, simplest matrix profile).
But… HTML reporting seems broken, report says 0 error to all, it looks like it is checking only WP & contrast.

After

pip install attrdict

I got

Same issue on Linux Mint 21, clena install of python 3 (3.10) and pip + virt env

Solved by

pip install attrdict3

(and uninstalling the other)

Hi please use the GitHub project page for error reports and support as there are more developers monitoring the issues over there: http://www.github.com/eoyilmaz/displaycal-py

[Samazar]

Hi Erkan, I am not a coder but really appreciate the bold step you have taken to continue to build DisplayCAL. In all honesty I am a bit lost in regards to the progress that has been made so far. I am interested to calibrate my home theatre projector without spending a ton. I know I’d need a good basic colorimeter like the i1 Display Pro.

1. Is there a new version of DisplayCAL available for use on Mac OSX platforms?
2. Would I need a 3D LUT Box that works with DisplayCAL – any recent developments in this area?

I’d appreciate it if someone could kindly provide perspective and guidance.

If this projector has a basic CMS and you may need to plug it to several “non computer sources” and you do not want to expend money on a lut box you may try playing with its CMS: RGBCMY + n points for gray balance.
Toying with these controls is usually easier on Calman or DisplayCAL’ “cousin” HCFR with is calman-like but GNU.

Unfotunately HCFR is Windows only AFAIK but you may try on a virtual machine since you’ll be using projector’s own CMS controls, no VCGT for grey or such things.

I’ll try this first before buying a lutbox.  Also if you can use a Windows computer there is a banding free software LUT3D working at system Level: DWMLUT.

Also there is no default colorimeter correction for blue laser projectors in Xrite software (there is a correction for older lamp based devices), maybe you can find them in community correction database or using some spectral distribution plot from AVS Forum if they own/reviwed your projector model.

Could someone please explain to a non-expert how to install this version on a Mac, as the official version does not work on macOS Ventura?

Does an installation package (dmg or sth) exist?

Thank you!

[Professor Fate]

As this discussion is already two years old: What is the current state of the Python 3 version of DisplayCAL? Unfortunately, SuSE has removed DisplayCAL from its repos, as the current production version is deprecated (because it relies on Python 2). After upgrading from OpenSuSE 15.3 to 15.4, it also disappeared from my machine, leaving me with an uncalibrated monitor. An alternative way for calibrating, gcm-calibrate, is no longer available either: It has been removed from the Gnome Color Manager.

@Erkan: When can we expect the new verison to become stable enough for production use? Thank you.
