You can make the text and other items, such as icons, on your screen easier to see by making them larger. You can do this without changing the screen resolution of your monitor or laptop screen. This allows you to increase or decrease the size of text and other items on your screen while keeping your monitor or laptop set to its optimal resolution.
Open Screen Resolution by clicking the Start button , clicking Control Panel, and then, under Appearance and Personalization, clicking Adjust screen resolution.
Choose one of the following:
Smaller - 100% (default). This keeps text and other items at normal size.
Medium - 125%. This sets text and other items to 125% of normal size.
Larger - 150%. This sets text and other items to 150% of normal size. This option appears only if your monitor supports a resolution of at least 1200 x 900 pixels.
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.
You can also make text appear larger or smaller by changing your screen resolution, but if you're using an LCD monitor or laptop, we recommend that you set your screen to its native resolution to avoid blurry text. This is the optimal resolution an LCD monitor or laptop screen was designed to display based on its size. For more information, see Change your screen resolution.
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.
Click Set custom text size (DPI) in the left pane.
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.)
On the Display screen, click Apply.
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.
If you set the dots per inch (DPI) higher than 144 while you're running Aero (the premium visual experience of Windows), text and other items on the screen might appear blurry in some programs that aren't designed for high–DPI display in this version of Windows. You can avoid this issue by using Windows XP style DPI scaling for these programs.
Select the Use Windows XP style DPI scaling check box, and then click OK.
