After seeing at Microsoft Store Surface Pro 3 connected to P2817Q (refresh rate 30) and producing 4K resolution I've bought a slightly up-level monitor P2717Q (refresh rate 60). Using Display Port I've tried to connect it to the docking station and directly to the surface. Using Win+P I've selected Extend option. In Screen Resolution control panel when I select Dell Monitor max resolution I see is 2560x1440. I am expecting 3840x2160. I've installed latest updates from MS (including all optional updates). It did not resolve the issue. Then I've installed latest drivers from Dell support. Issue did not go away. Any suggestions?

So I had exactly the same issue: Surface Pro 3 not detecting the native display resolution of the panel, either docked or undocked. However, I too resolved it by setting up a custom resolution using the Intel display drivers, as detailed here:

I got HDMI working in 4K @ 30 Hz in the end, it turned out to be a problem with the cable. Switching to Belikin Mini DisplayPort to HDMI adapter like this solved it:

The actual HDMI cable also matters a lot, only the original Samsung cable that came with the monitor worked, I tried several others and none would carry the signal.
I have not managed to get anything to work over the DisplayPort
I am using Display Port cable (mini DP connected to surface and DP connected to monitor) that came in the box with monitor.
I think it is the refresh rate. It looks like only 30 is supported. Interesting thread at http://answers.microsoft.com/en-us/surface/forum/surfpro2-surfhardware/surface-2-pro-and-dell-up2414q-4k-monitor-with/4a1449d7-4d2e-4ab5-ba7c-853f863d6b29?page=2
Much of that thread is about the Pro 2, but..

Which cable are you using to connect the SP3 to the Dell monitor?
