RE: My first week with the dell xps 13 Developer Edition 2015 (DE)
I installed the driver and everything I tested seems to work, usb, audio, and hdmi display, i did not test the network adapter.
The problem now, is the amount of resources needed to compress the video signal, the displaylink process alone is using 50% of the processor for a single fullhd display , I don't know if this is a bug or the expected behaviour. When using the hdmi dock output the fan is always on during non demanding activities like normal internet surfing, and watching a hd video through the dock display is frustrating because of the poor refresh rate.
I don't know if the windows driver behaves this way but I unistalled the dock and I'm not using it. I'm not going to waste half of the laptop resources continually only to output the video signal.
If you haven't yet, I recommend reporting this on DisplayLink's forum.
