Hi Andrea,
It's been a long time since I recalibrated my monitors, so I've kind of
forgotten the procedures...
I also use Argyll CMS with DisplayCAL, my colorimeter is an i1 Display Pro.
I don't go through the 1D LUT curve generation. Instead, I choose the
"as measured" option for the white level. I set the monitor brightness
to my liking (rather dark like the environment of the room concerned),
directly by the monitor controls.
In my case, I chose the "Rec. 1886" tone curve even though my monitors
don't really have the qualities of real monitors dedicated to color
correction.
I like the very smooth result and I find that I can pretty well evaluate
what the video will look like when presented on a TV.

Hi,
I don't know how many users do monitor profiling (I remember an old
discussion with Pierre...). It has been a long time since I did it but
now that I tried to do it again I have unsatisfactory results in terms
of brightness. The DeltaE is great (0.35) but the gamma is really
high, such that it hurts the eyes after a short time. Also, the custom
calibration disables the brightness/lightness OSD controls so I can't
lower it.
I used the Rec709 color space which has gamma 2.4 instead of the
normal 2.2 value of the sRGB space. Actually with a higher gamma you
should get darker results. My monitor (Dell UO2716D) is a wide gamut
type and natively supports various color spaces: sRGB; Rec709;
AdobeRGB and DCI-P3 (98%). It should have no problem with Rec709 at
gamma 2.4. Can you explain why I get too bright a result?
I use Argyll CMS with DisplayCAL and Datacolor Spyder5 colorimeter.
