The Advanced branch under Configuration - Editor Display has the following options:
Override default edit window dimensions
When a new document is created, it is automatically sized to fit the dimensions of the editor. This option overrides this autosizing with specific values. Note that if the dimensions of the editor are smaller than the specified height and width, the new document will be created with the old autosizing method.
Font Quality
Using this option the user may set the quality level Windows will use to render fonts in the editor. Information regarding the quality selected is displayed as the slider is moved. All options are available on a scale from Default to Best:
Default Quality
Draft Quality
Proof Quality
Non Antialiased Quality
Antialiased Quality
ClearType Quality
Natural Quality
UltraEdit/UEStudio should be restarted when the font quality is changed.
