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

  <p>You can change how big (or how detailed) things appear on the screen by
  changing the <em>screen resolution</em>. You can change which way up things
  appear (for example, if you have a rotating display) by changing the
  <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 on <gui>Displays</gui> to open the panel.</p>
    </item>
    <item>
      <p>If you have multiple displays and they are not mirrored, you can have
      different settings on each display. Select a display in the preview
      area.</p>
    </item>
    <item>
      <p>Select the resolution and rotation.</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 id="resolution">
  <title>Resolution</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>You can choose the resolution you prefer from the <gui>Resolution</gui>
  drop-down list. If you choose one that is not right for your screen it may
  <link xref="look-display-fuzzy">look fuzzy or pixelated</link>.</p>

<section id="rotation">
  <title>Rotation</title>

  <p>On some laptops, you can physically rotate the screen in many directions.
  It is useful to be able to change the display rotation. You can rotate what
  you see on your screen by pressing the buttons with the arrows.</p>
