[Toshiba dynadock U3.0] New docking station, audio and video lags

[EARNEST]

Hi all,

I've just purchased a new docking station, and I am having some audio stuttering issues (Inspire T6100, 5.1 system), image on a monitor being fuzzy, and the mouse cursor lags.
The mouse lags are more apparent if the "Optimize for video" feature is enabled.

I am running a Win8 x64 OS on my Clevo W870CU laptop through a USB3.0 port, with installed 7.0M0 on top of 7.0b1 drivers. The monitor is Dell U2412m.

Kindly advise. I would not want to return the item

Thanks in advance.

I can PM a mod with a ZIP file with debug info. I'd rather not post it here in the open.
