This makes it possible that your work (websites, images etc.) looks equal on somebody else's monitor, and that somebody else's work looks not different on your monitor.</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 colour 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> </chapter> <chapter id="using-kgamma"> <title>Using KGamma</title> <sect1 id="Setting-Gamma"> <title>Setting Gamma Correction</title> <para>To correct the gamma settings system wide, check the checkbox 'Store settings to XF86Config'. These settings will be restored at next XFree86 startup. You need root access to store to this file. This is, for example, useful for those who do not work exclusively with KDE.</para> <para>To correct the gamma settings for the currently logged in user, leave that checkbox unchecked. These user settings will be restored at next KDE startup and replace the system gamma settings. Every user has it's own settings.</para> <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 helps you to find proper settings.</para> </sect1> <sect1 id="Grey-Scale"> <title>Grey Scale Test Image</title> <para>You should be able to see the following:</para> <itemizedlist> <listitem> <para>A grey scale with 20 different sections</para> </listitem> <listitem> <para>The darkest section pure black</para> </listitem> <listitem> <para>The lightest section pure white</para> </listitem> <listitem> <para>No hint of any colour in the grey tones</para> </listitem> </itemizedlist> <para>If you can't see all of the 20 sections, use your monitors contrast settings or the "Gamma" slider of &kgamma; to correct this. If black is not pure black, try to darken the monitor, if white is not pure white, try to lighten it. If you see any colours in the grey tones alter the colour balance settings of your monitor or the "Red", "Green" and "Blue" slider of &kgamma;.</para> </sect1> <sect1 id="RGB-Scale"> <title>RGB Scale Test Image</title> <para> You should be able to see three strips, each with 16 sections of red, green or blue tones.
