<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>

<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>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>
</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>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 id="variable-refresh-rate">
<title>Variable refresh rate (VRR)</title>
<p>For smoother visuals and to optimize power consumption you can
synchronize monitor's refresh rate with content output.</p>
<note style="tip">
<p>VRR is different from Adaptive V-Sync (late V-Sync),
which dynamically toggles V-Sync based on frame rate. </p>
</note>
</section>
<section id="preferred-refresh-rate">
<title>Preferred Refresh Rate</title>
<p>Specify your preferred refresh rate to maintain optimal visual quality.</p>
</section>
</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>
