How ICC profile is associated to a specific monitor

[Nicola Farina]

Hi there,

another newbie question.

I have 4 identical display set as pair of 2 (1 set at home, 1 set at work).

If I profile my 2 displays at home, when I move my laptop to work, DisplayCAL Profile Launcher activates the same profiles, because, I suppose, displays model are the same. Is there a way to bind a profile to a specific display (like serial number f.e.)?

Thank you very much.

Hi,

This is one of the shortcomings of the Windows color management settings for monitors, it doesn’t really differentiate assigned profiles per monitor but per output. If you monitor’s EDID has some differentiating information (e.g. serial number as you mentioned), I might be able to work around this Windows limitation in a future version.

It would be a great feature! Actually, I have to avoid profiles because of this.

I’ve calibrated (not profiled) this four displays (brightness and RGB sliders) but non generated the profiles. Is this generally a better solution then using builtin monitor presets (“standard”, “video”, “games”, etc.)?

Thanks.

If implementing a workaround is possible depends on your monitors, they need to expose some differentiating information. You can check this by creating a profile from EDID for each of them (in DisplayCAL’s file menu), then checking the profile information. The lines beginning with “EDID_” in the right pane show what information is available. Unfortunately, some manufacturers don’t fill the serial, so this might not work.

Yes.

Yes.

In this case, how you suggest to set “whitepoint”, “white level” and “tone curve” in “Calibration” tab? All at “As measured”?

Thanks.

All “as measured” except whitepoint, as you are going to skip 1D LUT calibration anyway.
