Calibrate(1) Calibrate a Display.


Calibrate a Display


dispcal [options] outfile
-v [n]
Verbose mode
-display displayname Choose X11 display name
-d n[,m]
Choose the display n from the following list (default 1) Optionally choose different display m for VideoLUT access
1 = 'Screen 1, Output DVI-I-1 at 0, 0, width 1920, height 1080'
Display via a web server at port (default 8080)
-c listno
Set communication port from the following list (default 1)
** No ports found **
Report on the calibrated display then exit
Report on the uncalibrated display then exit
Skip adjustment of the monitor controls
-o [profile.icc]
Create fast matrix/shaper profile [different filename to outfile.icc]
-O "description"
Fast ICC Profile Description string (Default "outfile")
Update previous calibration and (if -o used) ICC profile VideoLUTs
-q [vlmh]
Quality - Very Low, Low, Medium (def), High
Use telephoto mode (ie. for a projector) (if available)
-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 blkbright
Set the target black brightness in cd/m^2
-e [n]
Run n verify passes on final curves
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.
Fill whole screen with black background
Don't set override redirect on test window
Encode the test values for video range 16..235/255
Run instrument calibration first (used rarely)
Disable initial calibration of instrument if possible
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, S&B 1955_2, shaw, J&V 1978_2, 1964_10c
-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
Base name for created or updated .cal and .icc output files
