# Change the resolution or orientation of the screen

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

Open the Activities overview and start typing Displays.

Click Displays to open the panel.

যদি আপোনাৰ একাধিক প্ৰদৰ্শন আছে আৰু সিহত মিৰৰ্ড নহয়, আপুনি প্ৰতিটো প্ৰদৰ্শনত ভিন্ন সংহতি দিব পাৰিব। পূৰ্বদৰ্শন স্থানত এটা প্ৰদৰ্শন বাছক।

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

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.

# Orientation

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

# বিভেদন

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.

You can choose the resolution you prefer from the Resolution drop-down list. If you choose one that is not right for your screen it may look fuzzy or pixelated.

# 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.

# Scale

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%.
