That is up to you. IDNK where you store files.
2021-05-03 at 19:42 #29963both LG TV before.icm and LG TV.cal are stored in O
2021-05-03 at 20:01 #29964also using C root …same issue
2021-05-04 at 8:53 #29969Output from command says the opposite. Also ICM is not attached.
2021-05-04 at 9:59 #29973well im confused , i really dont care what directory i gotta use , just help me get this to actually work , thanks , also heres the icm and cal files fresh from displaycal

Report bug to ArgyllCMS maillist (if it’s a bug). It’s not related to DisplayCAL, it’s related to ArgyllCMS.
.cal file seems OK (256×4, 1 input 3 outputs = 4) and I did not see something weird in base icm. I created a synth Rec709 profile with 2.2 gamma as TRC and same error.
Attach .cal in maillist and say that you want to attach that grey calibration to a sRGB/Rec709 simple matrix profile with 2.2 gamma. Maybe there is something wrong in .cal file that I cannot locate on a fast inspection. I’m using 2.1.2
2021-05-04 at 11:01 #29982even tho now ive simply renamed files accordingly to native names as such and put those also into the bin folder>
calfile.cal
inprof.icm
and opened command window inside the bin folder , then used following command>
applycal -a calfile.cal inprof.icm outprof.icm
i get following output now >
argyll: Error – rspl: rev_interp can’t handle di = 1071296905
yeah …guess ill have to bug report apparently indeed , damn it!
p.s also got the latest x64 build version

2021-05-04 at 11:23 #29986hell ive even made a batch to make this simple one click , but yeah above error is a bitch , batch>
@echo OFF
Title Convert .cal and .icm to working usable Full .ICM Profile
::Convert .cal and .icm to working usable Full .ICM Profile
cd /D “C:\extra\system tools\Argyll_V2.1.2\bin\”
applycal -a calfile.cal inprof.icm outprof.icm2021-05-04 at 11:56 #29990ive also contacted its creator directly , now we wait and hope for an update to support synth .cal integration into .icm, fingers crossed, also linked him to this thread

2021-05-06 at 14:39 #30043ok getting in contact directly with dev was gold…so far hes managed to get the process fixed atleast …so now you can atlest proper convert …BUT still for some odd reason dont proper integrate .cal file into .icm output file aka its not using the .cal settings
heres the updated applycal.exe from him for yourselfes to test out
https://www.argyllcms.com/win64_V2.2.1beta_applycal.zip
applying .cal by itself per DisplayCals menu vs the output.icm …youl see the difference in calibrations aka .cal not proper integrated into output.icm

2021-05-07 at 12:53 #30064It looks that is does not work that way. It changed TRC, not VCGT. It was meant fro printers! My fault.
Reading latest doc:NOTE that things like the white point, black point tag, gamut tag etc. are not adjusted to account for the calibration, nor does applycal read, add or change any ‘vcgt’ tag (If a ‘vcgt’ tag is present and a calibration applied as well, then both will be in effect when such a profile is installed using typical display installation tools.)
Diving into maillist:
Post by Stephen T
dispcal (which is all I want). Is it possible to insert the vcgt tag into any profile (sRGB
profile in my case)? How?Reply:
Not directly using Argyll. You could do it indirectly by creating an sRGB profile. You could
do this by creating a synthetic set of test points (say 5000-10000), use fakeread with
the sRGB profile to create the profile data, add the calibration curve table to the
data, and then create the profile using colprof. I’m not sure if that’s any easier
than what you are currently doing though !+

If you have a colorimeter using matrix+singlecurve + BPC and simplest 34 patch set will be the shortest way.

well , cant find what hes been instructing
also no color meter , i want my own hand tweaked synth .cal files vcgt added into .icm properly

2021-05-08 at 18:03 #30088He is saying that what you want won’t be included in DisplayCAL because users can mess with it and unless useed carefully obtain/forge inaccurate profiles.
As alternative he suggest to load grey calibration and then “profile only” display, but that needs a colorimeter.Maybe with a lot of effort you can forge/fake expected sRGB readings (in a synthetic way, like matlab or argylls icclu/xicclu) for 34 patch bassic matrix profile and make a .ti3, then feed it into DisplayCAL in File/create profile from measurement data.
In the same thread other vendors suggest they paid apps for what you want.
2021-05-09 at 9:48 #30097ok and you think you could atleast make both the profiles ive posted including theyre vcgts into a proper .icm each , till someone manages to post a tool that does said function aka integrate vcgt from .cal into .icm, would really appreciate
