DisplayCAL

1. My X-Rite i1 DisplayPro  is not plugged in.
   I start (as standard user) DisplayCAL 3.8.9.3 with ArgyllCMS 2.3.0 (64-bit) on Windows 11 x64.(please check 2 screenshots nothing-plugged.png and nothing-plugged-2.png)
   As you can notice, no “X-Rite i1 DisplayPro” instrument was detected.

Calibrate a Display, Version 2.3.0
Author: Graeme W. Gill, licensed under the AGPL Version 3
Diagnostic: Available ChromeCasts
usage: dispcal [options] outfile
-v [n] Verbose mode
-d n Choose the display from the following list (default 1)
1 = ‘DISPLAY2, at -2560, 0, width 2560, height 1440’
2 = ‘DISPLAY1, at 0, 0, width 2560, height 1440 (Primary Display)’
3 = ‘DISPLAY3, at 2560, 0, width 2560, height 1440’
-dweb[:port] Display via a web server at port (default 8080)
-dcc[:n] Display via n’th ChromeCast (default 1, ? for list)
** No ChromeCasts found **
-d madvr Display via MadVR Video Renderer
-d dummy Dummy (non-existant, invisible) display
-c listno Choose instrument from the following list (default 1)
1 = ‘COM1’
-r Report on the calibrated display then exit
-R Report on the uncalibrated display then exit
-m Skip adjustment of the monitor controls
-o [profile.icm] Create fast matrix/shaper profile [different filename to outfile.icm]
-O “description” Fast ICC Profile Description string (Default “outfile”)
-u Update previous calibration and (if -o used) ICC profile VideoLUTs
-q [vlmh] Quality – Very Low, Low, Medium (def), High
-p Use telephoto mode (ie. for a projector, if available)
-a Use ambient mode (ie. for a projector, if available)
-y l|c Other: l = LCD, c = CRT
-t [temp] White Daylight locus target, optional target temperaturee in deg. K (deflt.)
-T [temp] White Black Body locus target, optional target temperaturee in deg. K
-w x,y Set the target white point as chromaticity coordinates
-b bright Set the target white brightness in cd/m^2
-g gamma Set the target response curve advertised gamma (Def. 2.4)
Use “-gl” for L*a*b* curve
Use “-gs” for sRGB curve
Use “-g709” for REC 709 curve (should use -a as well!)
Use “-g240” for SMPTE 240M curve (should use -a as well!)
Use “-G2.4 -f0” for BT.1886
-G gamma Set the target response curve actual technical gamma
-f [degree] Amount of black level accounted for with output offset (default all output offset)
-a ambient Use viewing condition adjustment for ambient in Lux
-k factor Amount to correct black hue, 0 = none, 1 = full, Default = Automatic
-A rate Rate of blending from neutral to black point. Default 4.0
-b Use forced black point hack
-B blkbright Set the target black brightness in cd/m^2
-e [n] Run n verify passes on final curves
-z Run only verify pass on installed calibration curves
-P ho,vo,ss[,vs] Position test window and scale it
ho,vi: 0.0 = left/top, 0.5 = center, 1.0 = right/bottom etc.
ss: 0.5 = half, 1.0 = normal, 2.0 = double etc.
-F Fill whole screen with black background
-E Encode the test values for video range 16..235/255
-J Run instrument calibration first (used rarely)
-N Disable initial calibration of instrument if possible
-H Use high resolution spectrum mode (if available)
-X file.ccmx Apply Colorimeter Correction Matrix
-X file.ccss Use Colorimeter Calibration Spectral Samples for calibration
-Q observ Choose CIE Observer for spectrometer or CCSS colorimeter data:
1931_2 (def), 1964_10, 2012_2, 2012_10, S&B 1955_2, shaw, J&V 1978_2, 1964_10c or file.cmf
-I b|w Drift compensation, Black: -Ib, White: -Iw, Both: -Ibw
-Y R:rate Override measured refresh rate with rate Hz
-Y A Use non-adaptive integration time mode (if available).
-Y p Don’t wait for the instrument to be placed on the display
-C “command” Invoke shell “command” each time a color is set
-M “command” Invoke shell “command” each time a color is measured
-W n|h|x Override serial port flow control: n = none, h = HW, x = Xon/Xoff
-D [level] Print debug diagnostics to stderr
inoutfile Base name for created or updated .cal and .icm output files

2. I close DisplayCAL, connect “X-Rite i1 DisplayPro”, start DisplayCAL again.

Now no monitors are detected, the combo box is empty and not clickable. no “X-Rite i1 DisplayPro” instrument was detected.
