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

  <p>您可以在<em>屏幕分辨率</em>中，更改屏幕上对象的大小(或细致程度)。可以在<em>旋转</em>中，设置对象出现的方向(例如，您旋转了屏幕显示)。</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>分辨率</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>您可以在<gui>分辨率</gui>下拉列表中选择分辨率。如果选择错误，屏幕会变得<link xref="look-display-fuzzy">看着很模糊或花屏</link>。</p>

</section>

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