I encounter a lot of LCD monitors set to a low display resolution. Text and images are large but not crisp, and often the display ratio is incorrect, making people in photos look too fat or too thin.
If the person using the computer has very poor eyesight, then sometimes it is best to leave the display resolution set very low. However, there is a way of correcting the display ratio. Simply pick a display resolution that uses the same display ratio as the monitor.
This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g., orange indicates a 4:3 ratio)
The ideal method, though, is to start by setting the display resolution to that of the monitor, then work on increasing font, icon and image sizes to suit the new display resolution. The instructions are different for each operating system, so go to Microsoft's Display and Readability page and work your way through some of the suggestions there.
One important piece of advice that seems to be missing from the Microsoft instructions is changing the DPI setting in Windows XP.
What you may find is that text and images within particular programs also need to be resized to make them easier to view. Browsers will have options for changing the zoom level.
