How to Change DPI Scaling Size for Displays in Windows 8.1
In Windows 8.1
, you can now set DPI (Dots per Inch) scaling
to make text and other items, such as icons, fonts, and windows, to display larger or smaller for all displays or per-display.
Windows 8.1 DPI scaling improvements are primarily focused on:
- Optimizing the usability and readability of high-DPI displays
- Providing a uniform experience multi-display systems
- Empowering developers to optimize app-specific scaling based on display DPI
If you are running a screen resolution of 1366x768 on a tablet, chances are that UI will look good at 100% DPI settings. But what about when you connect that tablet to an external high resolution display? In Windows 8 you can choose either 100% to optimize the UI on the tablet display or up to 150% to optimize the UI on the external display. You have to compromise.
Windows 8.1 takes care of this issue by supporting per-display DPI scaling
to address. By default, Windows 8.1 will choose the optimum DPI scaling value for each display based on the value chosen for overall scaling in the control panel.
For more information, see:
This tutorial will show you how to change the DPI scaling
to make text and other items, such as icons, fonts, and windows, to display larger or smaller for all displays or per-display for only your account

Setting the DPI size to a smaller number or percentage will decrease all items size on the display(s), while setting the DPI size to a larger number or percentage will increase all items size on the display(s).
In Windows 8.1
