How to modify screen resolution on Ubuntu

You must have encountered the term screen resolution. The screen resolution plays a crucial role in providing an interactive display on the screen. You may have observed larger icons on your screen that state that you are using a low resolution. However, the higher screen resolution results in enhancing visibility and providing a better interface. This guide describes various methods that can be adapted to modify the screen resolution on Ubuntu.

How to modify screen resolution on Ubuntu

Like most Linux-based operating systems, Ubuntu also ships with graphical and command line support. One can perform all the tasks using the terminal and graphical support. The screen resolution can also be adjusted by using both methods as well. Let’s dig into them one by one:

How to modify screen resolution on Ubuntu using the terminal

The terminal support of Ubuntu requires careful execution but provides quick and accurate results. Follow the steps carefully to get into modifying the screen resolution.

Step 1: Open the terminal (CTRL+ALT+T) and use the following command to get the available resolutions for your screen.

Note: The xrandr provides command-line access to the RandR (Resize and Rotate) extension which is responsible for handling the outputs on your screen. Moreover, the xrandr tool ships by default in Ubuntu; this requires no installation.

$ xrandr

The output will show the current screen resolution, minimum and maximum resolution support available.

Step 2: To change the resolution to a specific value, you have to use either the “-s” or “–size” parameter of the xrandr command.

We have executed the following command to change the screen resolution to “1152×864“.

$ xrandr -s 1152x864

As soon as the command is executed, you will observe that the screen resolution will be changed to “1152×864” and your monitor screen will adopt a new resolution.

Moreover, you can use the “xrandr” command again to verify that changes are made successfully or not.

$ xrandr

From the output, it is observed that the current resolution is “1152×864” which states that the changes made in the above command are adopted successfully.

Step 3(optional): Apart from providing the width and height to change the resolution, one can use the aspect ratio as well using the “xrandr” command as we did in the following command.

$ xrandr -s 16:9

Although the aspect ratio and screen resolution do have some differences. However, aspect ratio also influences screen resolution, and thus it can be used to modify the screen resolution as well.
