XFCE has some support for HiDPI - you can change the setting across all monitors for HiDPI, but it doesn't vary between different screens in the way that it does on a Retina MacBook Pro. I'm using XFCE and Arch Linux on a Lenovo W540 with the high DPI display. Apart from Chrome not supporting HiDPI, things work well.
