Test

Focus adjustment(s)

Purpose

An out-of-focus monitor displays fuzzy graphic

 

images and poorly formed, hard-to-read text

 

characters.

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 that they affect

 

depend on the monitor you’re testing.
