<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>

<note style="tip">
 <p>When you use another display, like a projector, it should be detected automatically so you can change its settings in the same way as your usual display. If this does not happen, just click <gui>Detect Displays</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.</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

<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 choose the rotation
you want for your display from <gui>Rotation</gui> drop-down list.</p>
