How to Adjust DPI on Windows

There's a hidden preference you can use to get Postbox to display at various resolutions.  

  • Go to Options | Preferences > Advanced > General.
  • Click on the Config Editor button.
  • Search for: layout.css.devPixelsPerPx
  • Change this setting from 1.0 to something like 1.1 or 1.2.

Do NOT make this number too large or you will be unable to use Postbox!  We recommend 2 as a maximum value, but you can try incrementing up by .1 to see how each change works for you.
