Poll -Do you profile your displays?

[Vizioen]

So I'm intrigued again.

Would this be correct for an sRGB worfkflow:

Windows:

- I've enabled Use my settings for this device and loaded the Dell sRGB V2 profile on all 3 of my Dells and set it as a default. The same ICC profile I put in my VFB. (I can see a very very minor difference between that and the sRGB).




Do I touch anything else in the VFB? Rendering intent, black point compensation?

Do I change anything here in Windows?



Do I change anything here in Photoshop? And what about my old Photoshop files if I start using this workflow?



Do I change anything here in XnView?

icc profile you specify for your particular display (measured or downloaded) needs to manually go into VFB as 3dsMax does not see this profile. Photoshop or AffinityPhoto do and display colours correctly, no need to setup anything (edit: anything in the settings but you need to tag your files with correct profile, most likely srgb)
on my windows 10 I use the simple Photoapp for sanity check - it reacts to changing your display profile in rea time. affinity for example needs to be restarted. setup in Krita if fully manual and so on. XnView - no clue.

you can use the attached profile for easy tests - it is quite aggressive when some real life profiles might be hard to notice.

yes, icc profile in the Display correction on VFB is the textbook (within icc system) way of ensuring VRay looks like photoshops and other icc colour managed apps. old 3dsMax had an option for view lut and currently it is ocio system (which is by design supporting icc display profiles but support for ocio

So what is this workflow, and how does it differ from calibrating the display to use its own LUT (or even windows LUT) set to the calibrated sRGB and then using default vray settings (or OCIO)?

If the display itself is calibrated to sRGB with colorimeter then why would you need a display specific profile in the VFB? Wouldn’t you just tell the VFB to display the raw data as sRGB?

Perhaps I am missing something?

icc profile in windows does not work globally. it works in one app and does not work in another. hardware lut in the display sorts this issue.
3dsMax (so VRay too) needs to be managed manually.

I have a windows ICC profile on a third (Dell, not BenQ— no hw LUT) monitor and it seems to work in all apps. Maybe it is the Calibrite Display profiler that is keeping it active, not sure. But most of the time it works across all apps (sometimes fails to load requiring me to open windows displays once after a reboot).

Are you seeing some other behavior with Windows LUTs where they are not active all the time?

So in this setup where you use the ICC profile in the VFB how are you calibrating the monitor overall then? Leave the monitor the default settings and then only put the LUT on images displayed in the VFB, because the ICC profile in this case is designed to transform for that particular monitor? Why not put the LUT on everything (via windows) so all apps display the same? (Assuming windows keeps the LUT active all the time, which I am sure it does here, both win 10 and win 11. )

I'm not familiar with Calibright Display but if it works globally - problem solved, next best thing after hardware lut.
there are little tools like novideo_rgb or dwm_lut and they do work as expected. first loads colour matrix and 3x1d luts for RGB (per channel curves) into graphic card (so not full icc profile, 3d lut is missing) and second loads even fairly large cube luts seemingly without noticeable performance hit.

before any display profiling you should setup it as close to possible to the target with options available in the display settings.

The Calibrite software walks you through getting the monitor as close as possible to the standard before running through all the patches and creating the profile.
