HDPI was a hot topic at the qt world summit this week. I did not attend any talk about it, but what I heard is that qt 5.6 is supposed to be much better. I'd recommend anyone working on this to try 5.6 and have a look at the slides of the talks "High-dpi Qt" and "How to Develop with Qt for Multiple Screen Resolutions and Increase & Measure your Cross-Platform App Success (In-Depth Tech Session)" when they become available at qtworldsummit.com.
