This might be a dumb question, but is there any way to just make a high quality 1DLUT only?
When you run DisplayCAL “normally” the button is “Calibrate & Profile”
If we are using non color managed apps, then only the “Calibrate” part is even taking effect via the vcgt. Is there a way to skip the “Profile” step?
I realize that the profile part…[Read more]
SirMaster replied to the topic "Calibrating" a display for better colors with non-color-managed apps? in the forum General Discussion 1 month ago
Yes. DisplayCAL can do the “calibration” step which consists of a white balance and gamma calibration and this calibration is stored in your PC’s GPU’s gamma tables which will affect all output from the PC for any program.
When you do the calibration on the projector, make sure you adjust the R,G,B “Gain” controls under the white balance…[Read more]
I am pretty certain that the new i1Display Pro Plus is just the i1 Display Pro Rev.B OEM, but a “retail” version of the OEM.
And the i1Display Studio is just the ColorMunki Display re-branded.
If you kept your i1Display Pro in good conditions and it seems to work fine it is probably still fine.
Yeah I just notice that with say a ~100 point 3DLUT the result screen says like 89% P3 coverage, with ~500 points it’s like 92% and with ~1000 points it’s nearly 95% coverage, at least according to the results screen.
Measure the gamut hull (i.e. for each patch always at least one of R, G or B at 0% or 100%).
Is there some easy way to…[Read more]
Also, if I just want to measure the gamut coverage and volume of a display, what’s the easiest way to do that to get the most full measurement?
I notice that when I generate a 3DLUT, I get the measured coverage and volume, but I notice that the more patches I use for the 3DLUT, the larger the resulting coverage and volume % numbers I get.
If you have manual controls for the display, I recommend checking out HCFR for calibration.
You may need to use your own pattern source though like images or a video that you load on the phone and call up when you tell HCFR you are reading a certain patch, like 10% greyscale steps and primary/secondary colors at various saturations.
Another question is: Since the DisplayCal Profile Loader deactivates when I’m watching movies with madVR, does the calibration even affect the image in any way?
No (unless you have an nVidia card and enable “video overlay” in madVR options – calibration will then stay active for the desktop except for the video).
So the only way to make sure th…
Maybe this already goes without saying, but I will add my knowledge on this because I think it is helpful.
In madVR, in the calibration tab for the display there is a checkbox called “disable GPU gamma ramps”
If this box is checked, your madVR media player will have no calibration.…[Read more]
I will also add, you can try to do a BT2020 3D LUT for BT.2020 color profile mode on the projector, but you may find that you get posterization in the result.
In that case, try making your 3D LUT for DCI-P3 color space. I looked at your projector and it seems that Cinema 2 is the color profile to use for DCI-P3 color space.
It will then install…[Read more]
It’s switching to HDR because you told DisplayCAL that you are making an HDR 3DLUT by choosing the “Video 3D LUT for madVR HDR (D65 Rec. 2020 / SMPTE 2084 / BT.2390)”
You must not use this option as this is literally a HDR 3D LUT. You want to use madVR to tone-map HDR to SDR, so as you stated, you will be using SDR2020 which is NOT an HDR 3D…[Read more]
Argyll’s dispread has no ambient reading mode.
Just a heads up.
I communicated with Graeme about this and he said there is no real reason not to allow his tools to support ambient reading mode. He hadn’t added this mode before because measuring from the lens means you don’t factor in the spectral characteristics of the screen su…[Read more]
Is there any way to make DisplayCAL read normal spot measurements in ambient mode?
I can use HCFR to read in ambient mode and it seems to work well with a projector facing at the lens especially when trying to read really dark patterns.
I tried adding -a to the spotread command arguments in Advanced but that didn’t work, DisplayCAL will refuse…[Read more]
I tried pretty much every rendering intent, but “Absolute colorimetric with white point scaling” seemed to be the best.
I posted a few results here and included only the ones worth posting. The other rendering intents not included were even worse and jus tnot worth mentioning.
I’m not entirely sure what the lightspace guys are talking about,…[Read more]
I thought that you could use the diffuser to read from the lens, but yeah, I check the x-rite documentation and they only mention ambient mode with the diffuser and for projectors they only mention reading off the screen.
Thanks for setting me straight on that.
But look at the before 3DLUT picture. The Cyan secondary is out past the 75% saturation mark.
So clearly the projector is capable of that?
According to the manufacturer, the projector is supposed to be capable of 97% rec709 coverage.
After the…[Read more]
Does anyone know how to get the diffuser mode on the i1D3 to work with DisplayCAL for projector measurements?
I can have the meter with the diffuser on and I try to re-initialize the device etc, but when I try to calibrate, DisplayCAL just gives me an error that the meter is in the wrong mode or that it’s not getting a good reading.
I don’t see…[Read more]
Does the i1Pro2 work with HCFR or the vendor software? If so, please contact Graeme Gill (argyllcms.com) and send him the DisplayCAL.log from the ZIP file.
I have great news!
I sent the logs to Graeme Gill and he was able to reproduce the crash with some trickery and found a typo in the source code. He gave me some new test binaries, I dropped…[Read more]
Perhaps using DisplayCAL this is the case but youtube + chrome is definitely color managed.
Really? How do you do it.
No matter what I do, the 3DLUT in my .icm profile don’t apply to the YouTube video.
Also all the searching on Google I do points to people saying the same thing, that the video is not color managed.
