However, there are a number of new devices, particularly in the premium laptop and tablet markets, which have higher displays with over 200 DPI. Almost all desktop displays and most current laptop displays are in the range of 95-110 DPI for these devices, no scaling is required, and Windows sets a scale factor of 100%. This number depends on the display DPI as well as other factors that impact the user’s perception of the display. Windows ensures that everything appears on the screen at a usable and consistent size by instructing applications (including the Windows desktop shell) to resize their content by a scale factor. When a display has a higher DPI, pixels are smaller and closer together, so that the user interface (UI) and other displayed content appears smaller than intended.

DPI is a function of display resolution and size a higher resolution or a smaller size will lead to higher DPI, and a lower resolution or a larger size will lead to lower DPI. Dots per inch (DPI)) is the physical measurement of number of pixels in a linear inch of a display.
