Does anyone know if it's possible to use two 4K monitors with the HP Elitebook 840 G3 (via the Ultraslim docking station)?
All I can find is that maximum resolution is 4096 x 2160 at 60 Hz and that 3 independent displays is supported with the HP Ultraslim Docking Station.
Does this mean I can run 3 monitors at 4K resolution at once?

No. I'm in currently in the same situation. I have 2 4K monitors. Though the docking station powers them on, it only allows 1 to be at 4K (2560x1440) 4K, but even after upgrading dockinstation, display cards and monitor drivers for Window 10, it sees the Dell monitor as a Dell, but it only allows a max resolution of HD (1920x1080).
After calling HP support and verifying I had done the above. They finall told me "Oh, the Slim Docking Station can only run with 1 monitor in 4K mode at a time.
Would be nice for them to state that somewhere.
I have not found a replacement soluion yet

Yes, I got this answer from HP: "The dock itself can support 2x 3840x2160@30Hz as it is HW limitation of inside DisplayLink chip."
This means you can run two monitors in 4K@30Hz or one monitor in 4K@60Hz. Though 30 Hz is not ideal. Hopefully they will release a dockingstation that will support dual 4K@60Hz.
