Summary

+ This tool has several different but related functions. When given as + a file argument an ICC profile containing vcgt "gamma" curves, or an + Argyll video calibration .cal file, it will load that calibration + into the chosen display. It can also install or uninstall a profile + in the system for the chosen display, or set the display calibration + to that in the currently installed system profile. By default it + displays a test window the same as that used by dispcal and + dispread, to test this functionality. It can also be used to test + the ability to load video card LUT curves to each display, and to + test how the console Bell will sound when used with some instruments + (ie. Eye-One Pro).
+
+ [Note that in OS X 10.7 Lion, changes to the default system profile + permissions mean that you can't set a calibration persistently when + the default system profile is being used, unless you run as root + (ie. use sudo). Note that you do not + need to run as root to install a user profile (-Su, the default + install type.)]

Comments
+

+ The -v flag makes the program more + verbose..
+
+ display: + When running on a UNIX based system that used the X11 Windowing + System, dispwin will by default use the $DISPLAY environment + variable to determine which display and screen to read from. This + can be overridden by supplying an X11 display name to the -display option. Note that if + Xinerama is active, you can't select the screen using $DISPLAY or + -display, you have to select it using the -d parameter.
+
+ -d: By + default the location of the test window will be the main display. If + the system has more than one display or screen, an alternate + display/screen can be selected with the -d parameter. If you invoke dispwin so as to display the + usage information (i.e. "dispcal -?" or "dispcal --"), then the + discovered displays/screens will be listed. Multiple displays may + not be listed if they appear as a single display to the operating + system (ie. the multi-display support is hidden in the video card + driver). On UNIX based system that used the X11 Windowing System, + the -d parameter will + override the screen specified by the $DISPLAY or -display parameter.
+
+ Note that if VideoLUTs for a + display are not accessible (i.e. no hardware calibration + capability), dispwin will + will issue a warning or fail when it attempts to access them.
+
+ On X11 the inability to access VideoLUTs could be because you are + trying to access a remote display, and the remote display doesn't + support the XF86VidMode extension, or perhaps you are running + multiple monitors using NVidia TwinView, or MergedFB, and trying to + access anything other than the primary monitor. TwinView and + MergedFB don't properly support the XF86VidMode extension for + multiple displays. You can use dispwin -r + to test whether the VideoLUTs are accessible for a particular + display. See also below, on how to select a different display for + VideoLUT access. Also note that dispcal will fail if the Visual + depth doesn't match the VideoLUT depth. Typically the VideoLUTs have + 256 entries per color component, so the Visual generally needs to be + 24 bits, 8 bits per color component.
+
+ -d n[,m]Because +of +the + + + + + + + + difficulty cause by TwinView and MergedFB in X11 based systems, you + can optionally specify a separate display number after the display + that is going to be used to present test patches, for accessing the + VideoLUT hardware. This must be specified as a single string, e.g. -d 1,2 . Some experimentation + may be needed on such systems, to discover what screen has access to + the VideoLUT hardware, and which screens the test patches appear on. + You may be able to calibrate one screen, and then share the + calibration with another screen. Profiling can be done independently + to calibration.
+
+ -dweb or + -dweb:port starts a + standalone web server on your machine, which then allows a local or + remote web browser to display the the color test patches. By default + port 8080 is used, but this + can be overridden by appending a : + and the port number i.e. -dweb:8001. + The URL will be http:// + then name of the machine or its I.P. address followed by a colon and + the port number - e.g something like http://192.168.0.1:8080. If you use the verbose + option (-v) then a likely + URL will be printed once the server is started, or you could run ipconfig (MSWin) or /sbin/ifconfig (Linux or OS X) + and identify an internet address for your machine that way. JavaScript + needs to be enabled in your web browser for this to work.
+
+ Note that if you use this method of accessing a display, that there + is no access to the display Video Lookup tables, and that any + operation that depends on accessing the VideoLUTs will either + generate a warning or fail.
+
+ The -P + parameter allows you to position and size the test patch window. By + default it is places in the center of the screen, and sized + appropriately for the type of instrument. The ho and vo values govern the horizontal + and vertical offset respectively. A value of 0.0 positions the + window to the far left or top of the screen, a value of 0.5 + positions it in the center of the screen (the default), and 1.0 + positions it to the far right or bottom of the screen. If three + parameters are provided, then the ss + parameter is a scale factor for the test window size. A value of 0.5 + for instance, would produce a half sized window. A value of 2.0 will + produce a double size window. If four parameters are provided, then + the last two set independent horizontal and vertical scaling + factors. Note that the ho,vo,ss or ho,vo,hs,vs numbers must be + specified as a single string (no space between the numbers and the + comma). For example, to create a double sized test window at the top + right of the screen, use -P 1,0,2 + . To create a window twice as wide as high: -P 1,0,2,1.
+
+ The -F + flag causes the while screen behind the test window to be masked + with black. This can aid black accuracy when measuring CRT displays + or projectors.
+
+ By default dispwin will put + a test window on the selected display, and display some test colors, + before darkening  then brightening the screen by loading video + LUT values, test the bell sounds, then restore the original values + and exit.
+
+ If the -i + flag is set, then dispwin + will display the preset sequence, then random test colors forever.
+
+ If the -G + parameter is set, then dispwin + will display the sequence of RGB color in the supplied CGATS file, + e.g. a .ti1 file. Typically this might the used with the -m option to manually measure a + set of test patches.
+
+ If the -m + flag is set, then dispwin + will display the preset sequence then exits, but advances manually + after each return key.
+
+ If the -r + flag is set, then dispwin + will test just the loading of video LUT values by first darkening, + then lightening the screen, before exiting.
+
+ If the -n + flag is set, then dispwin + will display the colors directly on the display, rather than having + the color values translated through the currently loaded Video LUTs.
+
+ If a -s filename.cal option is + used, then rather than displaying a test window, dispwin will save the currently + loaded calibration curves to the given calibration file. Note that + other functions such as clearing or loading a calibration can be + performed after this action.
+
+ If a -c + flag is used, then rather than displaying a test window, dispwin will load the selected + display with a linear set of Video LUT curves, effectively clearing + the calibration, and will then exit. Note that other functions such + as loading a calibration can be performed after this action.
+
+ If a -V + flag is used, then rather than loading the calibration specified as + the final argument, the currently loaded calibration will be + verified as being the same as the given calibration file. If this is + combined with the -L flag, the currently + loaded calibration will be verified as being the same as the + installed system profile for the display.
+
+ -I: The ICC + profile specified as the final argument will be installed as the + default operating system profile for the chosen display, and the + display calibration will be set to the calibration tag ('vcgt' tag, + if any) in that profile.. On MSWindows and OS X this means that the + profile will be copied to the appropriate color profile directory + and registered with the operating system. For Linux X11 systems, the + profile will be installed using the ucmm + convention, and the X11 _ICC_PROFILE property in the root window, + and also the the XrandR 1.2 X11 _ICC_PROFILE output property on + systems that are running XrandR 1.2 or later. The latter is + following this convention + for allowing applications to locate the display profile for a + particular X11 display, and expands it to accomodate XrandR 1.2. + Note that for X11 systems, the properties are not persistent, and + will need to be loaded each time the X11 server is started (see the + -L flag).
+
+ -U: The ICC + profile specified as the final argument will be un-installed as the + default operating system profile for the chosen display. The display + calibration will remain unchanged.
+
+ -S d: Some + systems have more than one profile scope that an installed profile + will apply to, and this parameter allows overriding the default user + scope. On OS X, there is a choice of three scopes: n: for network scope, if people + are sharing profiles over a network, l: local system scope, which installs the profile + for all users of a system, and the default u, which covers just the user + installing the profile. On Linux or Microsoft Vista, just the local + system l and user u scope are available. Note that + you may need to run dispwin with elevated privileges(sudo) to be + able to successfully use network or local system scope. This option + also applies to uninstalling a profile. Note that to install a user + profile for the root account, you will have to login as root (sudo + will not achieve this).
+
+ -L: This + option fetches the current installed system profile for the chosen + display, and sets the display to the calibration tag ('vcgt' tag, if + any) in the profile. This is a convenient way of initializing the + display on system startup from the installed display profile, if the + system doesn't not do this automatically .
+
+ -E: Daemon + mode (experimental). When running on a UNIX based system that used + the X11 Windowing System, this option runs dispwin in a "daemon" + mode where it monitors the given X11 server, waiting for any changes + in monitors that may require loading a matching ICC profile (ie. + such as re-configuring, plugging in a different monitor etc.)  + This only works if XRandR 1.2 is available on the server. By default + dispwin runs silently, and will not terminate. If the -v option is given, it will emit + messages to stdout to show what it is doing. When it is first + invoked, it will load the installed profiles of all the screens of + the given X11 server.
+
+ The -D flag causes diagnostics to be printed + to stdout. A level can be set between 1 .. 9, that may give + progressively more verbose information. This can be useful in + tracking down why an operation fails.
+
+ The final optional parameter on the command line + is the name of an ICC profile that contains a Video LUT vcgt tag, or an Argyll .cal format display calibration. If + this parameter is provided, then the selected display will be loaded + with the given calibration. If the -V + flag was given, then it is verified that this calibration is the + currently loaded one.  This may be useful in initializing a + system to the current calibration on system startup, although a + better way may be to install the profile (-I option), and then just use -L. Note that the vcgt tag + interpretation within Argyll is consistent with that of the + originators of the tag. Other ICC profile vcgt implementations may + not be so consistent.
+
+ NOTE that on an X11 system, + if the environment variable ARGYLL_IGNORE_XRANDR1_2 + is set (ie. set it to "yes"), then the presence of the XRandR 1.2 + extension will be ignored, and other extensions such as Xinerama and + XF86VidMode extension will be used. This may be a way to work around + buggy XRandR 1.2 implementations.
+
+ NOTE
on MSWin systems that you will have to disable any + other calibration installer program if you want to be able to + control calibration using dispwin. Note also that there are other + programs that will interfere with calibration loading, such as + igfxpers.exe that gets installed with nVidia "Optimus" technology.
