ubuntu 14.04: USB 3.0 Display Video Adapter: extreme slow

Same issue here also

Connected two external displays and each of them is a bit laggy. Nothing impossible to handle, but still bothering sometimes when the mouse doesn't follow precisely...

Using xfce with xUbuntu.

Here is my dmidecode attached.

I recently just purchased an adapter with a DL-5xxx series chip and was unpleasantly surprised that when connecting two displays at 1080p it appears that it down clocks the refresh-rate to 30fps / Hz

Is that simply what is going on here? Am I wrong in my assessment that if we want two displays connected simultaneously, we're stuck at 30Hz?
