Okay, I figured out the problem. Here is the info for the monitor in question:
screen #0: dimensions: 1920x1080 pixels (351x191 millimeters) resolution: 139x144 dots per inch According to X the monitor has 144 DPIY. This is the minimum value which triggers HiDPI support in LibreOffice: (144 + 48 == 192) http://cgit.freedesktop.org/libreoffice/core/commit/?h=libreoffice-4-2&id=52cb1085edc66995393d5be5a55cb45b73a95292 There are at least two fixes: 1. Bump up the minimum value from 144 DPI (or only kick in if both X and Y are 144, etc.) 2. Port over this fix from master: http://cgit.freedesktop.org/libreoffice/core/commit/?id=9f308fbc02439e25f8932314a9374c205ebdbc4c It is also possible to use a better API for DPI such as xrandr that might give better information.
