Issues with High DPI displays (HiDPI)

JDownloader doesn't yet support HighDPI environments.
Because of this you may experience UI issues such as:

  • Blurry UI
  • Big letters in UI making it very hard to use JDownloader


HighDPI support requires a more recent java version (breaks backwards compatibility) and also the used LookAndFeel has to support it (and our current one doesn't fully).

At this moment all you can do is adjust some OS' settings.

In JDownloader:

  • Go to Settings -> Advanced Settings -> LAFSettings.fontrespectssystemdpi -> Restart JDownloader
