Greetings. I have calibrated many monitors over the years so am familiar with the basics of icc profiles, calibration, etc. However this is my first monitor that supports the writing of the calibration directly to the monitor chip if I use Asus ProArt Calibration software with my i1 Display Pro. It also supports this with the full version of Calman but I only have the home version which like i1Profiler, only generates software icc profiles.

I use the ProPhoto Colorspace in Lightroom and Photoshop and with my old monitors calibrated with i1 Profiler while set at full gamut which generated an icc that the color managed applications would respect.

With this new monitor and new Windows 11 PC, the default monitor driver installs these profiles:
Asus_Display_sRGB
Asus_Display_Rec709
Asus_Display_DisplayP3
Asus_Display_DCIP3
Asus_Display_BT2020
Asus_Display_AdobeRGB
It was set to Asus_Display_sRGB by default.
My plan is to calibrate the monitor in "Native" mode. It has preset "clamp modes" for the same color spaces listed above except there is no icc for "native". If I use the Asus ProArt software it will write the results as I understand it directly to the monitor (saved as a user mode) and does not generate an icc profile. So......since P3 is the largest color profile would I want to calibrate with that icc and also use that post-calibration? I think I read that the DCIP3 is smaller.

I know ProPhoto is larger than all of them and I know my monitor cannot display that whole range but I do not want to limit the range it is displaying by using the wrong icc profile. Also, the Asus ProArt Calibration software also just has the color space choices listed above so I need to choose one of those to calibrate to.

My understanding is color managed applications use the icc profile for mapping purposes........so if the color managed application is ProPhoto, and I calibrate with P3 and it is set to P3 post calibration, will that work? Or will it look to the stored values in the monitor. Regardless, I have to have some icc profile set for windows.

Conversely if the color managed app is sRGB would it know what to do?

Part of me just wants to use i1 profiler like I have for years, leave the monitor on Native, and just generate the profile with that. But I feel I am giving up one of the advantages of having this ProArt monitor if I don't use the ProArt Color Calibration that writes directly to the monitor. I know the software will calibrate and save to each preset but I do not want to do that. I will be using it with color managed applications mostly so do not need to use the preset. I need the monitor and profile wide open so LR ProPhoto can get the most color space it can.

Just looking to see if my thinking is correct and what the recommendation is.

I hope some of that makes sense :)
Thanks!

First of all ProPhotoRGB is a computational space not a display space. You can see from the chart below that ProPhotoRGB has some values that fall outside of the total visible curve. Using the i1 Display Pro app, generate an icc profile that matches the characteristics of your monitor. Save it and it will be listed along with the other profiles. In Windows set the ASUS display to use this new profile. Your colorimeter app should let you compare in chart from your new profile with Adobe RGB, sRGB, DCI-P3 etc. The color characteristics of your monitor will drift so recalibrate every month or so. As advertised, the icc profile that you generate should fall within 99% of DCI-P3 in the chart below.

Lightroom Classic will use the ProPhotoRGB as the default computational color profile. Your monitor will map the color values sent to it by LrC and every other app to fit within the assigned icc color profile. You want Windows to send to the display colors that the display is capable of producing. The icc color profile being applied will map any color value to a color value that falls inside the color profile being applied. It is the app sending that determines the color recieved by the monitor and displayed. The icc color profile sits between the app and the display to insure the color sent by the app will conform to a color that the display is capable of producing.

Obviously sRGB will conform to most any monitor. Which with is why it is the generic default. Your ASUS monitor was probably shipped with the i1 Display Pro colorimeter so the you can generate a color profile appropriate to your monitor AND room lighting conditions.

Thanks for that great reply! Do you think it would be worthwhile at all to do a calibration with Asus ProArt Calibration software first which writes to the monitor directly? And then use i1 Profiler to fine tune and generate a new icc?

I only use color-managed applications with the monitor so my sense was I needed an appropriate icc regardless of whether I did the hardware calibration or not....

Thanks!

I’m not familiar with “ASUS ProArt Calibration” software. My two Pro Art Displays came from the factory with a certified calibration.

If this software does what I think it might, it will tune the monitor such that a pure red (FF0000) and other colors will display as true and not something like “FF0108”.

If your monitor is not tuned at the factory and Calman verified, then you should run this software

I did get the factory calibration report for sRGB, P3-DCI and AdobeRGB presets. Was just going to validate.

Regardless, I agree I need to run Profiler to generate an icc..
