Luckily I am running Windows 7. It seems that despite having USB3 drivers installed from the factory that port on the Lenovo was operating at USB 2.0 speeds, the Intel drivers have fixed this, now there are no more slowness or lag issues - additionally the firmware update worked once USB3 drivers were installed.
Crazy really that these laptops come with USB3 ports and still no proper solution to ensure USB3 ports and devices are operating with the right drivers.
It would be good if DisplayLink could integrate something into their software to warn users if the dock is connected to a USB3 port but not operating at USB3 speeds.
Finally - this has not solved the issue of screen blurring/pixelation under heavy 2D graphics loads - I am desperately trying to get some visual evidence of this but you can't capture it with a screen-shot as the whatever buffer screenshots are grabbed from is before where the corruption/compression occurs. I'll see if I can get high-quality video of it happening. Is this also a known issue?
