Setting your computer to display larger fonts (PC)

Go to: Start > Control Panel > Display > Appearance > Font Size > change it to large or extra large


Using the zoom options (MAC OS X)

To enlarge screen data without changing the screen resolution you can use simple keyboard shortcuts to zoom in and out, select the following keys to operate this function:

  • option apple star (turns zoom function on)
  • option apple + (zooms in)
  • option apple - (zooms out)

Screen resolution

There are several ways you can enlarge the data viewed on your computer, but the first thing you should check is the screen resolution of your monitor. Your monitor will have a recommended screen resolution size, but maybe the settings have been altered or alternatively, you could alter the settings to best suit your visual requirements. Below is a list of common screen size options, your monitor may not display all these options, but take into consideration the higher the resolution, the smaller the screen data will appear.
