I just purchased a 4k Samsung Monitor (Samsung u28d590ds), and the problem is that when I connect to my laptop through hdmi the maximum available resolution is 1080×1920.
From what I understood is that I should be able to output 4k at 30 hz using the high speed hdmi cable that was provided with the monitor.
Laptop Hardware:
Nvidia Geforce Gt 650m 2 gb
Intel core i7 3630 qm with integrated intel HD 4000 graphics
I tried updating the drivers of the intel and nvidia graphics adapters, but the problem is still persisting.

This is an answer to a similar but not identical problem.
I bought a video card (PNY) with NVIDIA GeForce GT 730, connected by HDMI to a Samsung U28E590D 4k capable monitor. Windows 7 x64.
The NVIDIA Control Panel -> Change resolution screen shows HDMI - HDTV, and Ultra HD, but only with maximum resolution "1920x1080 (recommended)".
The Windows Screen resolution application: (Mouse right on desktop)->Screen resolution application is showing only 1920 x 1080.
I tried installing the Samsung driver from the CD that comes with the monitor, no help.
What finally worked was this.
NVIDIA Control Panel -> Change resolution -> Customize... then Create Custom Resolution... then Display mode Horizontal pixels: 3840 Vertical pixels: 2160 Refresh rate(Hz): 30.
Then, IMPORTANT change the timing from Automatic to one of the other choices. I think the best choice is "CVT reduced blank".
Automatic timing gives a very fuzzy screen. But one of the other timings apparently tell the video card to use native resolution correctly.
Aside 1: In the course of chatting with NVIDIA support, they pointed me at a tool that will show you what your monitor is telling your computer about its resolution and color capabilities: http://www.entechtaiwan.com/util/moninfo.shtm
Aside 2: This monitor is only 28". Full 4k resolution is very tiny. So I ended up creating a custom resolution of 2560 x 1440, 60Hz.
