<desc>Calibrating your screen is important to display accurate

<title>How do I calibrate my screen?</title>
<p>You can calibrate your screen so that it shows more accurate color. This
is especially useful if you are involved in digital photography, design or
artwork.</p>
<p>You will need either a colorimeter or a spectrophotometer to do this. Both
devices are used to profile screens, but they work in slightly different
ways.</p>
<steps>
<item>
<p>Make sure your calibration device is connected to your computer.</p>
</item>
<item>
<p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
start typing <gui>Settings</gui>.</p>
</item>
<item>
<p>Click on <gui>Settings</gui>.</p>
</item>
<item>
<p>Click <gui>Color</gui> in the sidebar to open the panel.</p>
</item>
<item>
<p>Select your screen.</p>
</item>
<item>
<p>Press <gui style="button">Calibrate…</gui> to commence the
calibration.</p>
</item>
</steps>
<p>Screens change all the time: the backlight in a TFT display will halve in
brightness approximately every 18 months, and will get yellower as it gets
older. This means you should recalibrate your screen when the [!] icon
appears in the <gui>Color</gui> panel.</p>
<p>LED screens also change over time, but a much slower rate than TFTs.</p>
