272How to Fix Program Scaling on 4k Monitors In Windows 10/8/7 [Tutorial]
If you're using a high-DPI 4Κ monitor or device (e.g. laptop) with Windows 10, you have probably already noticed that in some applications, the fonts are very small in the menus and the text, and you need a magnifier to read them. The above issue is caused because, because most desktop applications are "DPI unaware".* That means, that they do not automatically handle the DPI scaling and, as a result, will render blurry or will have wrong size.
DPI Awareness definitions: *
DPI Aware: The DPI Aware applications check for the DPI when they are started, and adjusts the scale factor whenever the DPI value changes. These applications are not automatically scaled by the system.
DPI Unaware: The DPI Unaware applications do not scale for DPI changes. They are always assumed to have a scale factor of 100 percent (96 DPI). These applications are automatically scaled by the system at any other DPI settings. By default, desktop applications are completely DPI unaware and are bitmap-stretched by Windows).
Dots per inch (DPI) is the physical measurement of number of pixels in a linear inch of a display. 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. 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.
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. This number depends on the display DPI as well as other factors that impact the user’s perception of the display. 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%. However, there are a number of new devices, particularly in the premium laptop and tablet markets, which have higher displays with over 200 DPI. For these devices, Windows sets higher scale factors to ensure that the user experience is comfortably viewable.
When you change the DPI scaling level for your displays, it changes the size of text, apps and other items to appear larger or smaller. A higher DPI level has everything appear larger, and a lower DPI level has everything appear smaller.
The default DPI level is 100% (96 DPI).
