<h2>Where display profiles are stored, and how to load them
automatically.<br>
</h2>
<br>
Installing a display profile for your monitor is very operating
system
dependent, which is why <a href="dispwin.html#I">dispin -I</a> is a
good way of taking care of all these details. On some systems it is
not
the operating system itself that
supports display profiles, but individual applications, or helper
programs.<br>
<br>
Please choose from the detailed instructions below that suite your
system:<br>
<br>
<span style="font-weight: bold;"><a href="#MSW">Microsoft
Windows</a><br>
<a href="#OSX">Apple OS X</a><br>
<a href="#Linux">Linux/UNIX X11</a></span><br>
<br>
<hr style="width: 100%; height: 2px;"><a name="MSW"></a>On <span
style="font-weight: bold;">Microsoft Windows</span>, display
profiles are typically in one of the
following directories:<br>
<p> MS Windows Me and 98: C:\Windows\System\Color<br>
</p>
<p> MS Windows NT:
C:\Winnt\system32\spool\drivers\color
</p>
<p> MS Window 2000, XP, Vista and 7:
C:\Windows\system32\spool\drivers\color</p>
<p>An alternative to using <span style="font-weight: bold;">dispwin
-I</span>
to install your display profiles,
is to use the Display
Property dialog, advanced settings, Color management tab, and
locate
the profile and install it there. This in
itself does not cause the profile to be made use of anywhere in
your
system.<br>
</p>
<p>If you are using Adobe Photoshop on your system, then you can
tell
it to use your monitor profile by editing the appropriate registry
key,
typically "My
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Color\Monitor\Monitor0",
to
contain the name of the display profile, and then restart
Photoshop
This is the simplest way of ensuring that the Adobe calibration
loader
tool Adobe Gamma loads the video hardware lookup tables from the
vcgt tag, and
uses the profile as its display profile.<br>
</p>
<p>The adobe gamma tool can be told to use your profile, but the
procedure is slightly tricky: Open adobe gamma from photoshop (in
the
Help->Color Management... menu item), select "Open Adobe
Gamma", and
select the "Load.." button. Select your profile and "Open". Select
"OK"
in the Adobe Gamma, it will then ask you to save it's modified
version
of your profile under a different name. Chose a name for the
modified
profile, and save it. Exit from Photoshop. Copy the profile you
want to
use, over the modified profile that you saved in Adobe Gamma. (If
you
don't do the last step, the profile Photoshop will be using will
have
been modified in strange ways from what you intended.)<br>
</p>
<p>Installing a profile on Microsoft Windows generally doesn't mean
that the profiles calibration will be automatically loaded into a
display on startup. A separated tool is usually needed to achiev
this.<br>
</p>
<p>Some Microsoft Windows applications may come with
"Gamma/VCGT/RAMDAC/Video LUT"
loader tools, consult their documentation and check your Start
Menu
Startup folders. If you don't want to use any of these 3rd party
tools, you can also use the <a
href="file:///D:/src/argyll/doc/dispwin.html">dispwin</a>
tool to do this for you, as it takes either a <a
href="file:///D:/src/argyll/doc/cal_format.html">.cal</a> or ICC
file
as an argument. The <a
href="http://freshmeat.net/projects/xcalib/">xcalib</a>
tool could also be used.<br>
</p>
<p>To add a startup item that will load a profiles calibration into
the
display using <span style="font-weight: bold;">dispwin</span>,
use the
following
instructions:<br>
</p>
<p style="margin-left: 40px;">On the task bar, right click and
select
"Properties", then select the "Advanced" tab, then click "Add..".
then
browse till you locate dispwin.exe. In the box containing the path
to
<span style="font-weight: bold;">dispwin.exe</span>, add a space
then
the option <span style="font-weight: bold;">-L</span>, eg:<br>
</p>
<p style="margin-left: 40px;"> <span
style="font-weight: bold;">c:\bin\argyll\dispwin -L</span></p>
<p style="margin-left: 40px;">If you don't want to use the default
installed profile, you could explicitly set the calibration file
to use
as an argument:</p>
<p style="margin-left: 40px;"> <span
style="font-weight: bold;">c:\bin\argyll\dispwin
c:\myprofiles\mydisplay.icm<br>
</span></p>
<p style="margin-left: 40px;">Click "Next >", select the
"Startup"
folder, then name the item (ie.
"Argyll Calibration Loader"), then press "Finish".<br>
<br>
You can test it out by simply navigating the "Start" menu to the
"Startup" folder and selecting the item you've just created. If
you
want to alter any of the details, navigate to the item again and
right
click it, and select "Properties". More than one startup item can
be
created to set the calibration for more than one display. You may
want
to cut and paste the "Target" line to a normal Command Prompt
shell to
check that it works as expected, as it is impossible to catch
error
messages in the startup.<br>
</p>
Microsoft Windows <span style="font-weight: bold;">XP</span> has an
optional <span style="font-weight: bold;">Microsoft Color Control Panel Applet for Windows XP</span>
available for
download from
Microsoft, which handles installation and registering of the a
display
profile, and will also automatically set the display calibration on
system startup. The applet is started from the control panel, and
first
you have to "Install..." the profile in the <span
style="font-weight: bold;">Profiles</span> tab, then associate it
with
the display in the <span style="font-weight: bold;">Devices</span>
tab, but <span style="font-weight: bold;">NOTE</span> that it seems
to
have a <span style="font-weight: bold;">bug</span>, in that it
sometimes associates the profiles with the <span
style="font-weight: bold;">wrong monitor</span> entry!<br>
<br>
On
Microsoft <span style="font-weight: bold;">Vista</span> you can set
the display profile in
Control Panel -> Hardware and Sound
-> Color Management, as an alternative to <span
style="font-weight: bold;">dispwin -I</span>. In Devices
you select "Use my settings for this
device", and then add the profile you've created.
Unfortunately
though, it doesn't use the 'vcgt'
calibration curves on system startup, so a tool such as <span
style="font-weight: bold;">dispwin</span> will still have to be
used
to do this. Note that currently Vista also has a <span
style="font-weight: bold;">bug</span> that causes the calibration
curves to be reset whenever the User Account Dialog (and similar) is
displayed. This problem can only be worked around manually, by
re-running the startup item whenever this happens. Note that due to
the
details of this bug it is necessary to actually reset the
calibration
to something else before re-setting it. This can be done quite
conveniently in dispwin by adding the <span style="font-weight:
bold;">-c</span>
flag: e.g.: <span style="font-weight: bold;">c:\bin\argyll\dispwin
-c
-L</span><br>
<br>
On
Microsoft <span style="font-weight: bold;">Windows 7</span> you can
set
the display profile by opening the <span class="phrase">Color
Management control by clicking the <span class="ui">Start</span>
button and then clicking <span class="ui">Control Panel</span>.
In the search box, type <span class="userInput">color management</span>,
and then click <span class="ui">Color Management</span>.</span>
Make sure the correct display device is selected in "Device:", and
then tick the "Use my settings for this device" box. Select "Add..."
and then "Browse..." to locate and load the profile. (Alternately
you can use the normal file browser to locate the profile, and then
right click on it and select "Install Profile". In the Color Manager
"Add..." dialog you can then select it.). Make sure that the new
profile has been marked "(default)" if you want it to be
automatically used for your display.<br>
<br>
By default Windows 7 seems to automatically load the default display
profiles calibration on startup, but needs to be told to do this at
all other times by changing the system defaults, or if some 3rd
party tool to load display calibration has been installed. This can
be done by logging on with a user account that has administrative
privileges, then opening the <span class="phrase">Color Management
(see above), and then select the "</span><span class="ui">Advanced</span>"
tab, and then "<span class="ui">Change system defaults...", then
select the </span><span class="phrase">"</span><span class="ui">Advanced</span>"
tab, and select/un-select the "<span class="ui">Use <span
class="notLocalizable">Windows</span> display calibration</span>"
check box. (You could use <span style="font-weight: bold;">dispwin
-I</span> as an alternative to this if you really wanted.)<br>
<br>
<br>
<hr style="width: 100%; height: 2px;"><a name="OSX"></a>On <span
style="font-weight: bold;">Apple OSX</span>, the display
profile are in one of the following
locations:<br>
<br>
/Network/Library/ColorSync/Profiles<br>
/System/Library/Colorsync/Profiles<br>
/Library/ColorSync/Profiles<br>
~/Library/ColorSync/Profiles<br>
<br>
Note though that /System/Library/Colorsync/Profiles is only
for
profiles supplied by Apple. You can use <a href="dispwin.html#S">dispwin
-S</a> to select the appropriate scope when installing a
profile
using <a href="dispwin.html#I">dispwin -I</a>. You can use the
"System
Preferences->Displays->Color" tool to check that the profile
has been installed correctly. Note that the contents of
the description tag (the argument to the <span style="font-weight:
bold;"><span style="font-weight: bold;">-D</span></span>
flag used with the <span style="font-weight: bold;">colprof</span>
tool) will be used to identify the profile.<br>
<br>
<hr style="width: 100%; height: 2px;"><a name="Linux"></a>On <span
style="font-weight: bold;">Linux</span> and other <span
style="font-weight: bold;">Unix</span> style systems, there is no
universally agreed location for ICC profiles yet,
although the following locations have been suggested at various
times:<br>
<br>
/usr/share/color/icc<br>
/usr/local/share/color/icc<br>
~/.color/icc<br>
<br>
although particular applications may use their own locations, such
as:<br>
<br>
/usr/local/share/Scribus/profiles<br>
<br>
Argyll <a href="dispwin.html">dispwin</a> follows uses the <a
href="ucmm.html">ucmm</a> scheme for storing user and system
display
profiles, and when a display is set to use a profile correctly, it
will
follow <a
href="http://www.burtonini.com/computing/x-icc-profiles-spec-0.2.html">this
convention</a> to make it available to applications.<br>
<br>
If you want the display calibration to be loaded, you should
consider
installing a tool to do so at startup, such as <a
href="file:///D:/src/argyll/doc/dispwin.html">dispwin</a>
or <a href="http://freshmeat.net/projects/xcalib/">xcalib</a>.<br>
<br>
Using <a href="dispwin.html">dispwin</a> the currently installed
profile for a particular display can be loaded using the <a
href="dispwin.html#L">-L</a> option of <a href="dispwin.html">dispwin:</a><br>
<br>
<span style="font-weight: bold;">dispwin -L</span><span
style="font-style: italic;"><span style="font-weight: bold;"></span><br>
<br>
</span>which will both upload the installed profile <span
style="font-style: italic;"></span>into the <span
style="font-weight: bold;"></span>root
window _ICC_PROFILE property, and also load it into the display
VideoLUTs. <br>
<br>
You can use the <span style="font-weight: bold;">dispwin</span> <a
href="file:///D:/src/argyll/doc/dispwin.html#d">-d</a> parameter
in
the usual way to select other
displays to store or load the calibration using the _ICC_PROFILE
property.<br>
<br>
To do this when you start your X11 server, you could put the above
command in your <span style="font-weight: bold;">.xinitrc</span>
file
in your home directory for each screen.<br>
