I recently changed over to a laptop with a 3200×1800 resolution screen, and QGIS no longer displays properly. Many items and font are too small and almost unreadable. Slight improvements can be made by changing style, icon size and font under Settings -> Options -> General, however issues still remain, particularly with pop up menus like attribute tables, etc.
Surely there are many users now with screens >1920×1080 resolution, experiencing similar problems?
I have read this question: Making icons and text larger on high resolution screen for QGIS?
And tried this solution: http://www.danantonielli.com/adobe-app-scaling-on-high-dpi-displays-fix/
It does not work for me. Are there any fixes? I'm finding this a major problem (particularly working from a 13" screen).
Edit: picture uploaded. You can see the inconsistency between the sizing of each element. The drop down plus symbols next to the layers can barely be seen let alone clicked accurately, ditto some of the other icons. Similar issues occur with pop up menus

It's an ongoing process to update the whole user interface to be compatible with hidpi screens. Basically it boils down to revisiting each icon which is not adapted and redo it. The last couple of days many icons have been updated.
Please try a recent nightly build (master version, to become 2.16 soon) and report issues for icons which are still not updated.
