<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>
26
<p>To change either of these options, click on your name on the top bar and choose <gui>System Settings</gui>. Go to the Hardware section and open <gui>Displays</gui>.</p>

<p>The resolution is the number of pixels (dots on the screen) in each direction that can be displayed. </p>
35
<p>You can choose the one you prefer from the options in the drop-down menu.
36
Notice that if you choose one that is not the right for your screen it may <link xref="look-display-fuzzy">look fuzzy or pixelated</link>.</p>
37
<p>To save the changes, click <gui>Apply</gui>. If the screen goes blank, wait for a minute and the settings will be returned to their previous values. Otherwise, click <gui>Keep This Configuration</gui> in the window that appears.</p>

<p>The resolution is the number of pixels (dots on the screen) in each direction that can be displayed.
50
Each resolution has an <em>aspect ratio</em>, the ratio of the width to the
51
height. Wide-screen displays use a 16:9 aspect ratio, while traditional
52
displays use 4:3. If you choose a resolution that does not match the aspect
53
ratio of your display, the screen will be letterboxed to avoid distortion.</p>
54
<p>You can choose the resolution you prefer from the <gui>Resolution</gui> drop-down
55
list. If you choose one that is not right for your screen it may
56
<link xref="look-display-fuzzy">look fuzzy or pixelated</link>.</p>
