I've just got the Lenovo Display Link USB 3.0 dock to drive my desktop monitors and frankly the performance is abysmal.

Issues include:
- Mouse lags and has very jerky movement across the screen, similar to using remote desktop across a slow connection. Performance is especially bad with 'mouseover' events on webpages, if the mouse travels over a link that causes a graphic change there is a noticeable stutter in the cursor's travel.
- When scrolling webpages or graphic heavy documents the entire screen sometimes 'blurs' and goes very pixelated for a couple of seconds. On pages with Flash or other animation, the screen may stay blurred permanently on that page - good example was the 'Captcha' game on the registration pages of this forum, I had to drag it onto the laptop's inbuilt screen just to be able to read it.
- Window animations and dragging windows around the screen is very jerky.

Things I have tried:
- Using the latest drivers from the DisplayLink website (using 7.3 M0): made no difference.
- Applying the firmware upgrade from the Lenovo website: the firmware update failed saying "!!!No Device Found!"
- Reducing screen resolution or only using one external monitor: made no difference.

I contacted Lenovo support with the above symptoms and they simply sent me a new dock, which has exactly the same problems, so now I have two crappy docks!

This must be driver related, because it can playback high-resolution video onto the external displays with no problems what-so-ever, but ask it to do something simple like drag a window from one screen to the other, or scroll a webpage the stupid thing just falls apart, pixelating and stuttering all over the place. The mouse issue is by far the worst, it makes me feel ill and makes performing precision operations in photo editing impossible.

I've seen many threads out there reporting similar issues. Has anyone come up with a solution, or even managed to get the firmware update applied successfully?

Thanks.
