In this guide we will learn how to manually adjust the DPI Scaling Level in Windows 10
What is DPI Scaling in Windows 10
Dots per inch (DPI) is the physical measurement of the number of individual dots that can be placed in a line within the span of 1 inch. DPI setting controls the size of the text, apps, and icons.
A lower DPI setting will make them appear smaller and a higher setting will make them appear bigger. By default, Windows has a setting of 96 DPI.
Although Windows automatically make it sure that the DPI level is adjusted optimally according to the screen type, display, and resolution of the device, sometimes you may want to change the DPI scaling level manually according to your viewing preference.

Change DPI Scaling Level FAQs
Changing the DPI level may affect working of some third-party or system applications that can lead to PC lagging.
Some games are built to run on a specific resolution only. So altering with scaling settings can stop them from launching.
Is there a registry change to also change the text size: title bar, menus, icons, etc from the default to something else permanently?
