Hi,
I couldn’t find it. Would you be able to provide some screenshots? As far as I know, Windows and most apps are not color-managed.
You won’t notice the effect when using sRGB profiles. However, if you set P3 color profiles for wide-gamut displays, any app that isn’t color-managed will display oversaturated images.
It has to be more than that, because as mentioned, novideo_sRGB adjusts the colors correctly based on the color space set on the monitor (even when using “Use EDID primaries”, and indeed reads different primaries values based on the selected color space).

Hi,
Thanks for your support. This option is not available to me. Do you know why? I have no clue. Could it be that DisplayCal is overriding this setting?
When I click on the Color Profile bar, nothing happens. I’ve already tried to find clear instructions in this forum but haven’t had any success.
Does ACM just not support any kind of real calibration at all? MHC2Gen page seems to allude to this but I don’t understand enough to interpret it correctly. With a CSC profile loaded that was generated from displaycal then converted with MHC2Gen, I get no improvement in gamma compared to native response and unfortunately my monitor doesn’t follow any target curve well on any of the 4 gamma modes. Additionally, the colour accuracy takes a nose dive compared to just EDID clamping via profile-less ACM and some RGBCMY adjustment on the monitor itself. I spent hours trying to make ACM useful but it just seems to produce across the board horrible and useless results? Is this feature basically good for only simple EDID-based sRGB clamping and nothing more?
I would just stick with novideo_srgb which simply works reliably, but with a HDR display now I find that novideo_srgb does not handle SDR<->HDR switching in Windows properly whereas ACM at least seems to be acknowledge that switching.
When I disable this feature on Win. 11 24h2 my colours are oversaturated. But when I enable it, colours look more alright, but I know it´s still a little bit off in some things.
Btw. I have created .ICC profile with ACM off, because when I was calibrating with ACM on, measuring was limited just to SRGB gamut. Which was not even on 99,9% like it normally is, it was on 98,2% SRGB.
When I have read about this feature in this thread, ACM it looks like this feature is not that reliable, so I would like to turn it off, but I don´t want my stuff to be oversaturated. What to do?
ACM/MHC2 supports better calibration than before. It’s 1D LUT supports higher precision than the old VCGT and it also supports a matrix for gamut mappings.
Attached an example profile which exemplifies both features: makes the screen darker and inverts red and blue (thanks to the matrix).
It’s more calibration software not being aware/supporting it.
Honestly, Windows is just terrible when it comes to proper color management. If you actually take this seriously, you’re better off switching to another operating system.
Too much information, not enough consistency, nothing is streamlined. Calibrate your display and rely only on color managed applications. But if you want to use a wide gamut profile, unfortunately everything that isn’t color managed will look oversaturated.Honestly, Windows is just terrible when it comes to proper color management.

But if you want to use a wide gamut profile, unfortunately everything that isn’t color managed will look oversaturated.It was working properly in color managed apps like Davinci Resolve, Photoshop and Windows gallery before on win. 11 23h2. Tho it was oversaturated systemwide but in apps mentioned it worked so that was enough for me.
Now I discovered that in Photoshop, Gallery it’s still working properly when I turn ACM off, but Davinci Resolve, VLC, chrome/YouTube colors are off.
I’m still on Windows 11 23H2, and for some reason, after a few updates, even though I profiled my monitor to sRGB, I’m now getting oversaturated colors on the desktop and in Explorer previews. Seriously, I give up. It seems like only Photos and Edge are actually color managed in Windows.
If you’re on nVidia, why not just use novideo_sRGB instead to clamp the colors to sRGB in SDR? YOu can even use your own color profiles. And I believe AMD has an sRGB clamp directly in their drivers.

You cannot “profile” to sRGB, not with DisplayCAL or i1Profiler or apps like that. You only calibrate greyscale and measure how it behaves at “current gamut of whatever your display preset is”.
Limiting gamut to sRGB can be done as Case explained above.

Maybe that’s why I’m still getting oversaturated colors in non–color-managed applications.
I switched my monitor to its built-in sRGB mode through the OSD menu, which limits the display’s native wide-gamut to the standard sRGB color space. After that, I used a hardware calibrator to fine-tune the grayscale, gamma, and white point, and then generated a custom ICC profile that describes how the monitor behaves in that sRGB mode.
In this setup, the OSD handles the gamut limitation, while the ICC profile simply characterizes the calibrated response for color-managed applications. This way, colors appear accurate in software that supports color management, without the typical oversaturation issues you get when using a wide-gamut mode without proper clamping.

Wow! I had no idea about this novideo_sRGB tool — now it all makes sense. So it’s actually possible to have accurate colors in Windows without having to limit the monitor’s gamut, right?
