I have a Thinkpad Yoga 2 --- 3800x1800 I think --- I find that the GTK-based stuff works well on HiDPI, but not automatically, so you need to fiddle with the GTK settings a bit. The QT stuff is worse since they cannot be fixed by adjusting only the font size. The older (Xaw3D,TK) stuff is really bad. I have never seen different DPI on different displays working. 99% of my day is spent in the terminal (xfce4-terminal) though and the crisp text makes it all worth while.
