[argyllcms] absolute new to calibration/profiling in total confusion. (long post)

Good morning to all,
For first sorry for my English, is pretty awfull so have patience.
i'm trying to calibrate two LCD an eizo 1931,(pretty new) and a Neovo
f17 (old one)  but results, that's for sure better than previous done with
eye 1 match..to my eyes seems to tend to be "warm"  on the eizo.

As i think a calbration/profiling of a monitor as for every other thing have
to be done following the work needs, i start from that.
The profile i'm searching to do is for photo editing, that for now have not
to be printed but viewed on web.
so i want calibrate the f17 as much close as possible to srgb..
And the Eizo,  the best calibration in absolute  possible, for the
lcd characteristics and for photo editing.

As an only video workflow, i suppose the best match as to be 6500°K gamma
2.2 as "standard"  the colorimeter is an i1 display lt (old one gretag..)

What i've done so far and the question in order to correct eventual mistake,
or suggestion how to obtain a better profile....

deleted the previous I1match 3 profile. reset to default the eizo.

Note always i notice this warning? what is this?  Warning - RegOpenKeyEx
failed with 2, it seems not influence any operation.

dispcal -v -d 2 -r -y l

dispcal -v -d 2 -qh -y l -T6500 -e10 EIZO_tatgetA

 question about.. -T -t options... white daylight  or white blackbody?
excuse my ignorance but if ,i suppose, whyte daylight  first is the  same as
1one match do when i calibrate to 6500°  what is the white balck body ?
which of the two options are better for my needs? and if someone could
explain why in an easy way..
then is better an L curve? or better leave the gamma on 2.2?
and the brightness as i see affect the color response, and i've to fine
tune r-g-b gains, which is the more usefull the 140cm^ as seen on web or is
only a common pratice?

Another question, as the 1931 as only brightness and a  gain for the r-g-b
i suppose that i've only to calibrate using option  2 and 3 right?

 1) Black level (CRT: Brightness)
  2) White point (Color temperature, R,G,B, Gain)
  3) White level (CRT: Contrast, LCD: Brightness)
  4) Black point (R,G,B, Offset)
  5) Check all
  6) Continue on to calibration
  7) Exit



next step  targen -v3 -d3 -e20 -f2000 EIZO_displayA

i choose f2000 as a good number of patches for the Eizo...
the -e 20 (to test various whites ) is too much?
others option usefull?  the others seems to me targeted on printers..

nex step dispread -v -d2 -yl -k EIZO_tatgetA.cal EIZO_displayA

next and final step  profile -v -D"EIZO_DISPLAY" -qh -y -al -dmt
EIZO_displayA
L profile everywhwere seems to be said are better...
-y i suppose verify that the conversion to rgb values is correct...
-dmt is how i work so i suppose is the right choice..
i excuse me, don't understand the 90% of other option  there's others
usefull?

After that i wull try to do the work for the Neovo,the lcd that will help me
out to better guess what the world outside will see my photo,
Is  indeed a really strange lcd, with backlight regulation,
brightness-contrast and gains for lcd.. so i suppose will be a little more
complicate (and is old really old 2003 so the lamp have a "cold" tendences)


thanks for any help
