|
<para>This document describes &kgamma; version 1.0.2 (KDE 3.2)</para>
|
|
<para>&kgamma; is a tool for monitor gamma correction. With proper gamma
|
|
settings, your display (websites, images, etc.) will look the same on your
|
|
monitor as on other monitors.</para>
|
|
<para>&kgamma; allows you to alter the monitor's gamma correction of
|
|
XFree86. But that's not all to do. For good results you have to set the
|
|
correct brightness, contrast and color balance of your monitor. This
|
|
may be difficult and you have to repeat every step several times.
|
|
For perfect results you need really good (and expensive) hardware.</para>
|
|
<para>This are system settings, please do not use &kgamma; to manipulate your
|
|
image files.</para>

<title>Setting Gamma Correction</title>
|
|
<para>Use the four sliders to define the gamma correction either as a single
|
|
value, or separately for the red, green and blue components. The XFree86
|
|
default setting for gamma is 1.00 (Mac 1.80, WinXX 2.20). The test images help
|
|
you to find proper settings.</para>
|
|
<para>To store the gamma settings system wide, enable the option 'Store
|
|
settings to XF86Config'. The system settings will be restored at next XFree86
|
|
startup. You need root access to use this option. Use this if you want to
|
|
correct the gamma settings for all users and graphical environments on this
|
|
machine.</para>
|
|
<para>To store the gamma settings to your personal KDE configuration, do not
|
|
enable that option. The user settings will be restored at next KDE startup and
|
|
replace temporary the system gamma settings. The system settings are not removed by
|
|
that and will be restored at next XFree86 startup.</para>
|
|
<para>On multi head systems, select the screen you want to alter with the combo
|
|
box. This will also work with xinerama enabled. If you want to set all screens
|
|
to the same gamma values, enable the 'Sync screens' option. On systems with only
|
|
one screen this option will take no effect.</para>
