Linef4ult is absolutely correct, in regards to #1.
The #2 option is a good solution as well, according to the english version of the web site, it'll work fine. The adapter supports multiple displays, without mirroring, so it will effectively daisy chain the monitors. But I suspect that the adapter / splitter requires specific windows drivers to be installed. So this may not work with Linux, Unix, etc.
Edited, see below for better solution.
But absolutely DO NOT use VGA for those monitors. VGA will not give you a clear image. (I hope that Linef4ult meant an HDMI to DVI adapter, or DVI to HDMI adapter).
Instead of VGA, use the Mini DP and DisplayPorts, or use the 2 HDMI ports. While not daisy chaining, the Mini DP, and Displayport ports, are relatively low hassle.

Okay, I missed something. According to Dell, this monitor supports DisplayPort Chaining.
Outputs:
- 2 HDMI(MHL) connectors
- 1 Mini DisplayPort
- 1 DisplayPort (version 1.2a)
- 1 DisplayPort out (MST)
- 1 Audio Line out (connect your speakers)
- 4 USB 3.0 ports - Downstream (4 at the back, 1 with battery charging)
- 1 USB 3.0 port - Upstream
So you should just be able to plugin one display port cable into the computer, and then one from the monitor to the other monitor. Without installing any windows drivers, etc.
