Best settings for Asus Pa27uc-k

Hello folks,

New to the forums but not new to forums.
First, big thanks to Steve. I'm a DP and have learned so much about the tech side of monitors!
I have a few questions for the gang (and Steve?) but wanted to list my items in the tool box.

Laptop with CS LTE
Pi 4 board with the latest TED patches.
i1 display pro color meter
I1 pro 3 Spectro ( not a fan but thats what i have)
Asus Pa27Uck
My question is. What is the best mode for that monitor for pre cal? I have it set to user 1 and have cleared luts inside. Not sure is maybe rec 2020 might be a better option?

The second questions is about the i1 display pro. I have many drop down choices in the Cor.files and I'm not sure which one to choose. I read somewhere that RGB LED is best.

And the last question is about probe matching and the i1 display probe. Since I am using my i1 pro 3, do I really need any Cor.file for the i1 display pro? Can I just leave it blank? I figure I'm using the i1 pro 3 as the correlation. Yes?
Any help would be great.

Thanks so much!

Steve

I would say just follow the ASUS User Guide: https://www.lightillusion.com/asus_manual.html

As with any monitor calibration you do not want the monitor pre-set to any colour space.
You want the monito set to its fully uncalibrated/native state.
You then set black/white levels, and maybe set the white point colour temp - but that's not really necessary.

This is all explained in the main 3D LUT Calibration Guide: https://www.lightillusion.com/3d_lut_guide.html

And if you are using the i1Pro for Probe Matching you do not want to also use a Correlation File - again as per the User Guides.

Hi Steve,

Thank you so much for your reply. So my understanding was correct on the Correlation files. Great. I have also combed through the Asus manual on your site, and as suspected, User 1 is the way to go. But I did not find any info on correlation files in the manual. And I looked everywhere on the web. So I dont know.

Do you think its worth probe matching these two meters? The low light speed of the i1 display pro and the color for the I1 pro 3? I know the i1 pro isnt the best but It is what I have.

Thanks again for your Help Steve,

Steve

Yes - probe matching is the best approach.
If there is a Correlation File available, that can be used, but probe matching is nearly always preferable.

Great! Thanks. Im going to give your MPVM workflow a shot! Im using the same approach that you outline where i do a rec 709 followed by an Extraction. Then Do the 4 point MPVM. Cant wait.

Thanks again Steve!

I'm not actually sure what you mean by "...where i do a rec 709 followed by an Extraction. Then Do the 4 point MPVM."

I was fallowing your video on display calibration. I thought you first ran a grey ramp in a target gamut / EOTF that was rec 709. Then take that profile and extract it. Then, in a new color space window you choose that extracted space. I thought it was to profile the display against itself. So I thought I would have to follow the same procedures for probe matching. But maybe I am doing an extra step since you added the Null in the Target Gamut /EOTF. I am going to go through your video manuals again to make sure I am getting this, I hope im at least grasping the ideas correctly.

Thank you for keeping up on the post Steve.

No - that process has nothing to do with Probe Matching.
The Extract Colour Space process is just to asses the underlying native display capabilities to itself.
Which video exactly were you watching?

Abd I'd start with the normal 4 measurement FCVM probe matching before trying MPVM.
Get to understand the workflow first.

Hi Steve,

Ok. Lets take out probe matching just to simplify things and make sure i've been correctly profiling.

I was watching your video on your site on display calibration. Following things step buy step. Where I got confused I guess is after I got my white and black point set, thats when I thought I would then extract the space so I can profile the monitor in its native space? Unless thats wrong? I think I have a firm grasp if your software but maybe not?

Thanks

Steve

No - you do not need to 'extract' the colour space at all.
That is just to asses the underlying native display capabilities to itself.

It may be better to follow the text User Guide: https://www.lightillusion.com/3d_lut_guide.html

Ok. I'll try that more in depth and see how it works out for me.

Thank you Steve
