A couple weeks ago I upgraded to a Fujitsu Lifebook u904, for the 14" QHD (3200x1800) display. I was surprised at how very well it works with Linux, given how little information I could find about compatibility.
Gnome hasn't got their act together yet around high-resolution displays so font configuration is a bit wonky but that's not a hardware incompatibility deal-breaker. Even the touch-screen works.
