And to further add, if I calibrate to a black offset within the icc profile I set. Is that something color managed applications are aware of, or should I just manually crush them with novideosrgb? I was curious to how srgb may display when using a black offset if it is baked into the icc profile and translates it.
I test a little bit more
On Samsung monitor calmp to sRGB icc dont work, nothing changes. Clamp to displayP3 and rec.2020 synthetic icc profiles work, why is that?
On KTC monitor the situation is the same, only the edid is wrong
You should describe *exactly* what you are doing and how do you have things set up, and also what “doesn’t work” means. Your descriptions so far are very chaotic and unclear. If the clamp works with EDID, it should work with a correct ICC profile too.
On my wide gamut Samsung monitor clamp to sRGB using edid is working fine, but clamp using icc profile (sRGB) produce no desaturation of colors (checking it on youtube page on red logo)
I dont see effect in action, red colors dont became less red.
But the clamp to displayP3 and rec.2020 icc synthetic profiles work, I see desaturation in action!
So the program is working, but why I not see the effect of applying sRGB icc profile?

This sounds like you’re trying to use the Windows sRGB profile as the ICC profile used for the clamp. If that’s what you’re doing, then it will obviously not do anything, because you’re essentially telling the application you’re already in sRGB.
You have to use a specific device profile, ideally (obviously) your own calibrated profile – if you don’t have one and can’t make one, you’re better off just using EDID.
The Windows sRGB profile is set as the default for your device in the Windows color management options, not used as the ICC profile within novideo_sRGB.
Can you be more specific, I dont get everything that you write?
In windows cms I assign regular diplayP3 profile from apple to my monitor. But there is also an advanced tab with device profile, that I do not touch, and there is sRGB profile by default. I dont understand what this is doing, its a working space profile or what?

which configuration?
EDID: find out EDID values, if they are sRGB it wikll not clamp and it’s monitor fault. Also EDID srGB simulation with novidoe sRGB is ment to be use with an OSD preset with NATIVE GAMUT and no further transformations (no Rec2020 mode et cetera)
ICC profile:
Check rXYZ, gXYZ and bXYZ of profile. If they are widegamut open a ticket on novideo_sRGB github.On KTC monitor the situation is the same, only the edid is wrong

novideosRGB should not care about your color management settings since it is meat to simulate colorspaces like if they where inside monitor.
Hence test of desaturation should be done on non color managed software like MS paint or a photo on windows wallpaper. Better to use MS paint.
Once novideo_sRGB is simulation something, or DWMLUT or any other tool including HW calibration or factory modes, for color managed app you need to set as display profile the colorspace you are simulating, then restart the app if you opeed it before chaning the profile in OS settings.
Default display profile must match display behavior (inclusing GPU simulations) when color mamaged apps starts.Can you be more specific, I dont get everything that you write?
Not sure how I can be more specific, but since you’re posting screenshots, I guess that might be a way in case I was not clear enough.
In Windows color management, use sRGB for the device in question (first screenshot).
I never even touched the Advanced tab (second screenshot). That’s beyond my current knowledge anyway.
In novideo_sRGB, select your actual ICC profile for your monitor (third screenshot).
Thank you all for the answers
But still for me program is not working correctly or I just dont understand how it is working
- EDID clamp to sRGB works
- ICC clamp to displayP3 and rec.2020 also works (I created this synthetic icc profiles in displayCal)
- ICC clamp to sRGB dont work(
Word “work” I mean colors desature
Like I understamd this program should read color primaries of the gamut inside icc profile and reduce color space accordingly
Why this is not happening?
Here are the screenshot
There is no many optins to choose from
When I check – calibrate gamma to sRGB, shadows became less deep
Like I sad before its a synthetic icc profile created in displayCal with sRGB primaries and eotf = 2.2
But also I try synthetic sRGB profile created in phtoshop and sRGB profile that bundled with Windows, they all dont work
Dont understand why is that, its a bug or something else?
