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

-o [profile.icc]

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

-O "description"

Fast ICC Profile Description string (Default "outfile")

-u

-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]

-A rate

Rate of blending from neutral to black point. Default 4.0

Set the target black brightness in cd/m^2

-e [n]

Run n verify passes on final curves

-z

-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

-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

-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"
