You can change how big (or how detailed) things appear on the screen by
|
|
Packit |
6d2957 |
changing the screen resolution. You can change which way up things
|
|
Packit |
6d2957 |
appear (for example, if you have a rotating display) by changing the
|
|
Packit |
6d2957 |
rotation.

If you have multiple displays and they are not mirrored, you can have
|
|
Packit |

different settings on each display. Select a display in the preview

area.

<title>Resolution</title>
|
|
Packit |

|
|
Packit |
6d2957 |
The resolution is the number of pixels (dots on the screen) in each
|
|
Packit |
6d2957 |
direction that can be displayed. Each resolution has an aspect
|
|
Packit |
6d2957 |
ratio, the ratio of the width to the height. Wide-screen displays use a
|
|
Packit |
6d2957 |
16∶9 aspect ratio, while traditional displays use 4∶3. If you choose a
|
|
Packit |
6d2957 |
resolution that does not match the aspect ratio of your display, the screen
|
|
Packit |
6d2957 |
will be letterboxed to avoid distortion, by adding black bars to the top and
|
|
Packit |
6d2957 |
bottom or both sides of the screen.
|
|
Packit |
6d2957 |
|
|
Packit |
6d2957 |
You can choose the resolution you prefer from the <gui>Resolution</gui>
|
|
Packit |
6d2957 |
drop-down list. If you choose one that is not right for your screen it may

On some laptops, you can physically rotate the screen in many directions.
|
|
Packit |
6d2957 |
It is useful to be able to change the display rotation. You can rotate what
|
|
Packit |
6d2957 |
you see on your screen by pressing the buttons with the arrows.
