To create a custom DPI scale

Windows gives you three preset choices (100%, 125%, or 150%) for making text, icons, and other items on your screen larger than normal size. This is the quickest and simplest way to change their size. But if you prefer, you can change their size to any number between 100% and 500% of normal size using the custom dots per inch (DPI) scale.
1. Click to open Display.
2. Click Set custom text size (DPI) in the left pane.
3. Click the scale (ruler), drag the setting to whatever percentage size increase you want (100%-500%), and then click OK. (If you prefer, you can type a number between 100 and 500 in the box next to Scale to this percentage of normal size, and then click OK.)
4. On the Display screen, click Apply.
   To see the change, close all of your programs and then log off of Windows. This change will take effect the next time you log on.
   Customize the size of the text that displays on your screen.

   Note

   • If you set the DPI too high for your display, it can increase the size of some items by so much that they no longer fit on your screen.
