Hi Nic,
I've attached my System information as requested.
I'm running a 13.3” Series 5 Ultrabook (NP530U3C-A07AU), with latest Intel HD Graphics 4000 driver.
I even tried to install the AMD catalyst one but the laptop refused to install it.
I'm getting the Code 43 error on the driver properties page...
The main issue being that I can't switch to my 22inch Samsung Monitor as it's not recognised.
Hope there's a solution soon.
