<title>Change the resolution or orientation 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>

      <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 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>

<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>

<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>

</section>

<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>
