Hi, I have the same laptop, and I've got some disappointing news - the Intel HD4400 cannot handle 4K from either the DP 1.2 or HDMI 1.4 port. This is stipulated on Intel's spec page for the processor, be it the i5 or i7 ultrabook series. Dell has capped it at QHD I think on a software level, although the integrated graphics should be able to output a maximum of 3200x2000@60Hz.
Thank you for the reply, ATR123. I have continued testing, and by connecting my monitor directly to the laptop via HDMI I can obtain the full 3840x2160 resolution, just not through the docking station & display port. I am waiting for a minidisplay port cable to arrive because it would fit better.
I have the latest Intel drivers 10.18.15.4279.

Glad to hear you got it working. HDMI 1.4 bandwidth limits you to the 24/30Hz, and I would be interested to hear if mini-DP bumps up the refresh rate. I used to own a P2415Q, but it was limited to 24Hz off my e7240, which caused a lot of mouse lag, etc. Perhaps Intel has enhanced 4K support in their latest driver release, and I would consider going back to 4K from my current U2715H if this is the case.
kingskib, I also have an e7240 with the HD 4400 graphics running Windows 8.1. I'm going to buy either a UHD or WQHD monitor. I'm hoping that you can tell me:
Is the text on your UHD monitor so small that you have to scale it up? Is the text about the same size as on the 12.5 touchscreen on the e7240?
Does the laptop offer the UHD setting when you plug the monitor into your laptop? I have an external HD monitor now and it only shows up to 1920x1080.
What is your personal opinion after having used both UHD and WQHD resolutions for business productivity work--which do you like better? I'm concerned that having to scale may not work well because I hear some programs don't handle scaling very well.
(1) Yes when I go with the max resolution (3840x2160) the text is too small and I have to scale up the text.
(2) I am not sure what you are asking. I am no longer using the docking station because when I use the Display Port on the docking station the monitor goes to sleep after some time of inactivity and then does not start back up with the full resolution. It became very annoying so I now use my monitor plugged in with the HDMI cable when docked.
(3) I am running 2560x1440 and like this resolution the best for work purposes. I was having mouse lag and issues connecting remotely when at the max resolution.
