Win7 + Nvidia + Toshiba Dynadock - Flickering display

[CSparrow]

Logs as per request

Have discovered something

When running diagnostics on KFUltrabook mentions USB 3.0 driver may be issue (logs supplied)

Have updated firmware and driver on another unit (TBUltrabook)
Then made sure running latest 310.90 nvidia driver
Also then updated displaylink driver to 7.1M1
Now I have a different fault
Constant screen flashing (rename file to remove .zip off end of file)
(see logs and video)
If you disconnect the dynadock the display will stop flashing

Windows event logs show pretty much nothing
