<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

<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>
