NAME

Calibrate - Calibrate a Display.

DESCRIPTION

Calibrate a Display

SYNOPSIS

dispcal [options] outfile

Verbose mode

-display displayname Choose X11 display name

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)
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
Create fast matrix/shaper profile [different filename to outfile.icc]
Fast ICC Profile Description string (Default "outfile")
Update previous calibration and (if -o used) ICC profile VideoLUTs
Quality - Very Low, Low, Medium (def), High
Use telephoto mode (ie. for a projector) (if available)
White Daylight locus target, optional target temperaturee in deg. K (deflt.)
White Black Body locus target, optional target temperaturee in deg. K
Set the target white point as chromaticity coordinates
Set the target white brightness in cd/m^2
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
Set the target response curve actual technical gamma
Amount of black level accounted for with output offset (default all output offset)
Use viewing condition adjustment for ambient in Lux
Amount to correct black hue, 0 = none, 1 = full, Default = Automatic
Rate of blending from neutral to black point. Default 4.0
Set the target black brightness in cd/m^2
Run n verify passes on final curves
Run only verify pass on installed calibration curves
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)
Apply Colorimeter Correction Matrix
Use Colorimeter Calibration Spectral Samples for calibration
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
Drift compensation, Black: -Ib, White: -Iw, Both: -Ibw
Override measured refresh rate with rate Hz
Use non-adaptive integration time mode (if available).
Don't wait for the instrument to be placed on the display
Invoke shell "command" each time a color is set
Invoke shell "command" each time a color is measured
Override serial port flow control: n = none, h = HW, x = Xon/Xoff
Print debug diagnostics to stderr
Base name for created or updated .cal and .icc output files
