The Kensington SD4000 USB 3.0 docking station is a very easy way to connect to a single 4K resolution display or a pair of 2K displays even if your laptop technically lacks the ability to support it.  The small 19.5x85x2.75cm (7.7×3.3×1.1") connects to your laptop via a USB 3.0 connection and provides three USB 3.0 out, a LAN Port and DVI, DisplayPort and HDMI out, as well as separate mic and headphone jacks.  There is a sliding plastic cover over the DP and HDMI ports as you can only use one at a time, an handy way to distinguish which one is active.  eTeknix plugged in a 4K display and had no issues getting and external display to show full resolution, though they did not test gaming performance.  As this dock is intended for business and productivity focussed users that does make sense, if that describes you then check out the review.

"For today’s review I’m venturing a little bit out of my normal area of storage, network, and server components and take a closer look at a very useful gadget for everyone that has a laptop of some sort. Kensington might be most known for their locking system that is present on almost any electronic device, but they do make a lot of different products too. Today I’m taking a closer look at the SD4000 Universal USB Docking Station for laptops."
