There are several ways to change the monitor or video card settings on a Linux system. Here are some options you can try:
xrandr command is a utility that allows you to configure the display settings of your graphics card. You can use it to set the resolution, refresh rate, and other display options. Here's an example of how to use xrandr to set the resolution to 1920x1080:$ xrandr --output <output> --mode 1920x1080
displays: The displays command is a graphical utility that allows you to configure the display settings of your graphics card. It provides a user-friendly interface for adjusting the display settings, including the resolution, refresh rate, and other display options.
Desktop environment settings: Many desktop environments, such as GNOME, KDE, and Xfce, include their own settings utilities for adjusting the display settings. You can usually find these settings in the "System Settings" or "Control Center" of your desktop environment.
Configuration files: Some graphics drivers allow you to configure the display settings by modifying configuration files. For example, the NVIDIA graphics driver uses the /etc/X11/xorg.conf file to configure the display settings. However, this option is generally more advanced and is not recommended for most users.
Note: The specific steps for changing the display settings will vary depending on your graphics card, driver, and desktop environment.
