  <title>Change the resolution or orientation of the screen</title>

  <p>Vous pouvez modifier la taille (ou la précision) des éléments qui apparaissent à l'écran en modifiant sa <em>résolution</em>. Vous pouvez changer la façon dont les éléments apparaissent (par exemple, si votre écran est pivoté) en modifiant la <em>rotation</em>.</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>Si vous avez plusieurs écrans et qu'il n'y a pas la même image sur tous les écrans, vous pouvez avoir des réglages différents sur les écrans. Sélectionnez un écran dans la zone d'aperçu.</p>
    </item>
    <item>
      <p>Select the orientation, resolution or scale, and refresh rate.</p>
    </item>
    <item>
      <p>Cliquez sur <gui>Appliquer</gui>. Les nouveaux paramètres seront appliqués pendant 20 secondes avant de revenir à l'affichage précédent. De cette façon, si vous ne voyez plus rien avec les nouveaux paramètres, vos anciens paramètres sont automatiquement restaurés. Si vous êtes satisfait des nouveaux paramètres cliquez sur <gui>Conserver cette configuration</gui>.</p>
    </item>
  </steps>

<section id="orientation">
  <title>Orientation</title>

  <p>On some devices, you can physically rotate the screen in many directions.
  Click <gui>Orientation</gui> in the panel and choose from
  <gui>Landscape</gui>, <gui>Portrait Right</gui>, <gui>Portrait Left</gui>, or
  <gui>Landscape (flipped)</gui>.</p>

  <note style="tip">
    <p>If your device rotates the screen automatically, you can lock the current
    rotation using the
<media its:translate="no" type="image" src="figures/rotation-locked-symbolic.svg"><span its:translate="yes">rotation lock</span></media> button at the bottom of the <gui xref="shell-introduction#systemmenu">system menu</gui>. To unlock, press the 
<media its:translate="no" type="image" src="figures/rotation-allowed-symbolic.svg"><span its:translate="yes">rotation unlock</span></media> button</p>
  </note>

</section>

<section id="resolution">
  <title>Résolution</title>

  <p>The resolution is the number of pixels (dots on the screen) in each
  direction that can be displayed. Each resolution has an <em>aspect
  ratio</em>, the ratio of the width to the height. Wide-screen displays use a
  16∶9 aspect ratio, while traditional displays use 4∶3. If you choose a
  resolution that does not match the aspect ratio of your display, the screen
  will be letterboxed to avoid distortion, by adding black bars to the top and
  bottom or both sides of the screen.</p>

  <p>Vous pouvez choisir votre <gui>Résolution</gui> dans la liste déroulante. Si votre choix ne convient pas à votre écran, l'image peut paraître <link xref="look-display-fuzzy">brouillée ou pixelisée</link>.</p>

</section>

<section id="native">
  <title>Native Resolution</title>

  <p>The <em>native resolution</em> of a laptop screen or LCD monitor is the
  one that works best: the pixels in the video signal will line up precisely
  with the pixels on the screen. When the screen is required to show other
  resolutions, interpolation is necessary to represent the pixels, causing a
  loss of image quality.</p>

</section>

<section id="refresh">
  <title>Refresh Rate</title>

  <p>The refresh rate is the number of times per second the screen image is
  drawn, or refreshed.</p>
</section>

<section id="scale">
  <title>Scale</title>

  <p>The scale setting increases the size of objects shown on the screen to
  match the density of your display, making them easier to read. Choose
  <gui>100%</gui> or <gui>200%</gui>.</p>
