Hi, I just got a 1920x1080 14" laptop, this fairly high but not huge DPI. I have set the Windows 7 scaling to 125% which is small but OK. I migrated my Qt4 app to Qt 5.4.1 (at last...) and use the fusion style.
With the default settings, it seems the app is not DPI aware : everything is very small. I have tried the various WindowsPlatform = dpiawareness = 0,1,2 in qt.conf, without any effect. I have tried setting QT_DEVICE_ASPECT_RATIO environment variable to 2. Then the whole style is scaled, except the font, which stay exactly the same size : very small. What can be the problem? All my UI was done with Qt4 designer, and for instance the toolbox title bars use "MS Shell Dlg 2"font, size 8 (By the way, I do not know why QtDesigner used this font everywhere) Thanks for helping!
