When I first saw this adapter, I did not know this was possible to even do. I use it on my surface pro and mirror to my large screen tv, while at the same time mirroring the signal to my monitor at my desk. With this I am able to use it both as my multimedia pc and my desktop computer. Most important thing to note is that you MUST HAVE display port 1.2 or above for this to work.
As well as mirroring you can also extend, so you can have different things on either one of the monitors you have connected. Essentially it gives you two separate monitor connections from the one mini display port! No installation was needed, it was all automatic and could immediately configure in windows display settings.
One very important thing to keep in mind is that this adapter needs external USB power to function. So therefore you need to plug it in to either the USB port on your device, or a wall adapter for it to work. Not really a big deal, and it comes with the cord to do so.
Overall I am quite happy! Kept me from spending 200 dollars on a docking station.
