Purpose
An out-of-focus monitor displays fuzzy graphic
images and poorly formed, hard-to-read characters
when text is displayed on the screen.
Method
On monitors with a single (static) focus adjustment,
adjust the control for the best average focus over
the entire screen. The focus at certain locations of
the screen should be within specified limits.
Some monitors have a static and one or more
dynamic focus controls. The sequence for adjusting
them and the areas of the screen they affect depend
on the monitor you’re testing.
