Most applications will automatically get along fine with high pixel density. If you spot an application with unreadable or extremely small fonts, please tell us via the TicketSystem and we'll fix it.

Matlab requires a manual change to scale its graphical interface on high density monitors. Type these commands in the Matlab GUI:
>>settings;s.matlab.desktop.DisplayScaleFactor>>s.matlab.desktop.DisplayScaleFactor.PersonalValue = 2
and re-start Matlab afterwards.
Hints:
Some Matlab releases are buggy and won't safe these changes (e.g. Matlab 9.15 a.k.a R2023b). Use a different Matlab release in that case.
