  <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>
