Change the appearance of the size of a monitor screen by changing the resolution and the display scaling settings. Both of these methods can make objects on the screen appear either smaller or larger.
Each monitor has a default native resolution that can be changed from within the Windows, Mac or Linux operating system. Increasing the resolution of a screen makes objects on the screen appear sharper but smaller, while reducing the resolution makes them larger but less focused. Display scaling works in a similar way, but instead of changing the resolution, it changes how individual applications appear and makes them look larger or smaller.
