Generally speaking, Qt should scale for High DPI displays (automatically on Unix, apparently there's potentially something to be done on Windows) and do about fine.
But, if happen to not like the automatic scaling that Qt does, there's a way to actually customize exactly the scaling factor you want, and which also applies to Unix systems (Ubuntu and macOS), by using Environmental Variables

For eg you could set QT_SCALE_FACTOR=1.5 and see the difference. On my ubuntu, I can just pass that as I launch the app for eg:
QT_SCALE_FACTOR=1.5 /usr/local/openstudio-2.9.1/bin/OpenStudioApp
