Configuring display options to optimize for a resolution of 800x600
The screen resolution affects the way the user interface looks like. Small screen resolutions could cause problems or uncorrectly displayed pages. This option allows you to optimize the user interface for a screen size of 800 x 600 px.
When you use this option the user interface will be optimized for small screens. Eg. too long words in the message subject are hard hyphenated.
