Windows 7 users can enlarge the text display on the monitor screen for better readability. The Windows Control Panel has "Display" options that include three sizes: "Smaller – 100%" (default), "Medium – 125%" and "Larger – 150%." The medium and larger settings expand the document's area and reduce the surrounding gray background. The Desktop icons also appear larger. These display settings do not affect a file's font size on a printed document.
Click the Windows "Start" button or press the "Start" key with the Windows logo.
Click the "Control Panel" in the right pane. A list of computer settings appears.
Click "Display." This button displays a computer screen at an angle. A dialog window entitled "Make it easier to read what's on your screen" appears.
Click the option for "Medium – 125%" or "Larger – 150%."
Click "Apply." A window's message asks you to log off to apply these changes.
Click "Log off now" to save the display change.
Log on to view the enlarged text.
Some open documents will not fit the screen if the display setting is too large.
To add a custom size option, click the “Set custom text size (DPI)” link in the left pane of the “Display” dialog window. A ruler appears in a window. Drag the ruler to a preferred setting, such as "200%." A preview of the effect appears. Click “OK.” This custom option appears below the “Larger” option.
