<section id="steps">
  <title>Set up an additional monitor</title>
  <p>To set up an additional monitor, connect the monitor to your computer. If
  your system does not recognize it immediately, or you would like to adjust
  the settings:</p>

  <steps>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
      start typing <gui>Displays</gui>.</p>
    </item>
    <item>
      <p>Click <gui>Displays</gui> to open the panel.</p>
    </item>
    <item>
      <p>In the display arrangement diagram, drag your displays to the relative
      positions you want.</p>
      <note style="tip">
        <p>The numbers on the diagram are shown at the top-left of each
        display when the <gui>Displays</gui> panel is active.</p>
      </note>
    </item>
    <item>
      <p>Click <gui>Primary Display</gui> to choose your primary display.</p>

      <note>
        <p>The primary display is the one with the
        <link xref="shell-introduction">top bar</link>, and where the
        <gui>Activities</gui> overview is shown.</p>
      </note>
    </item>
    <item>
      <p>Click on each monitor in the list and select the orientation,
      resolution or scale, and refresh rate.</p>
    </item>
    <item>
      <p>Click <gui>Apply</gui>. The new settings will be applied for 20
      seconds before reverting back. That way, if you cannot see anything with
      the new settings, your old settings will be automatically restored. If
      you are happy with the new settings, click <gui>Keep Changes</gui>.</p>
    </item>
  </steps>

</section>

<section id="modes">

  <title>Display modes</title>
    <p>With two screens, these display modes are available:</p>
    <list>
      <item><p><gui>Join Displays:</gui> screen edges are joined so things can
      pass from one display to another.</p></item>
      <item><p><gui>Mirror:</gui> the same content is shown on two displays,
      with the same resolution and orientation for both.</p></item>
    </list>
    <p>When only one display is needed, for example, an external monitor
    connected to a docked laptop with the lid closed, the other monitor can be
    switched off. In the list, click on the monitor you want to disable, and
    turn the switch to off.</p>
      
</section>

<section id="multiple">

  <title>Adding more than one monitor</title>
    <p>With more than two screens, <gui>Join Displays</gui> is the only mode
    available.</p>
    <list>
      <item>
        <p>Press the button for the display that you would like to
        configure.</p>
      </item>
      <item>
        <p>Drag the screens to the desired relative positions.</p>
      </item>
