    Hi,

    I recently rebuilt my Probook 4540s Win7 64bit, and all is fine & dandy.

    Apart from one, crucial, aspect - I can no longer duplicate my screen over to another device. I've tried with a Hitachi Projector and a HP monitor. But no luck.

    In device manager, there are a couple of unknown devices - see screenshot - which I just can't seem to find the drivers for.

    btw - when I plug in the monitor, it does show up in 'Devices and Printers' as functioning well.

    Any advice very gratefully received!
    Edit: it's an Intel HD Graphics 4000 card.
