Change the resolution or orientation of the screen

Per definire quanto grandi (o quanto dettagliati) gli oggetti appaiono a schermo, modificare la risoluzione dello schermo. Per definire il modo in cui appaiono (per esempio, con un monitor ruotabile), modificare la rotazione.

  1. Open the Activities overview and start typing Displays.

  2. Click Displays to open the panel.

  3. 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.

  4. Select the orientation, resolution or scale, and refresh rate.

  5. Click Apply. 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 Keep Changes.


On some devices, you can physically rotate the screen in many directions. Click Orientation in the panel and choose from Landscape, Portrait Right, Portrait Left, or Landscape (flipped).

If your device rotates the screen automatically, you can lock the current rotation using the rotation lock button at the bottom of the system menu. To unlock, press the rotation unlock button


The resolution is the number of pixels (dots on the screen) in each direction that can be displayed. Each resolution has an aspect ratio, 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.

È possibile modificare la risoluzione dall'elenco a discesa Risoluzione. Se questa non è adatta per il proprio schermo, gli oggetti potrebbero sembrare strani oppure pixelati.

Native Resolution

The native resolution 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.

Refresh Rate

The refresh rate is the number of times per second the screen image is drawn, or refreshed.


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 100% or 200%.
