DESCRIPTION

Calibrate a Display

SYNOPSIS

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’

-dweb[:port]

Display via a web server at port (default 8080)

-c listno

Set communication port from the following list (default 1)

** No ports found **

	-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.icc]

Create fast matrix/shaper profile [different filename to outfile.icc]

-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)

-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/mˆ2

-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/mˆ2

-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
	-n		Don’t set override redirect on test window
	-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, 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

inoutfile

Base name for created or updated .cal and .icc output files
