Windows 8 issues - USB display adapter

[AaronC]

Hi, I am running windows 8 on a new Lenovo w530. I have installed, uninstalled, reinstalled drivers etc countless times (including all the ways suggested in this thread) and have had no luck). When wanting to extend my display I get the flashing screen. If I instead duplicate my display my second screen goes black, but has a windows arrow in the centre and my primary screen switches to low resolution, but the flashing ceases. If I switch my secondary screen to off (ie only keep my primary display) then my resolution of my primary screen goes back to normal and the secondary screen goes blank.

Log from the displaylink support tool is attached below (I ran the tool while the primary screen was flashing)

Any help suggestions would be much appreciated.
