Hi,

Originally, digiKam follow FreeDesktop specification (before to use a dedicated
database to store         
thumbs), and maximum size was limited to 256x256. This specification is also
used by all other program, as Dolphin or Gwenview.

http://specifications.freedesktop.org/thumbnail-spec/thumbnail-spec-latest.html

I understand the UHD screen size problem with thumbs. I fully agree that
something must be done in this way.

512x512 sound like a good compromise. Don't forget that we use PGF wavelets
compression format in DB to optimize space storage and quality.

Note that only digiKam can be improved in this way. Showfoto which use
thumbnails for thumbbar do not use a DB, but old FreeDesktop standard.
