    Hi,


    I posted this yesterday in Laptops, but might get more traction here.



    I recently rebuilt my Probook 4540s Win7 64bit, installed new chipset and drivers from the HP site. It has an Intel HD Graphics 4000 card

    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 Base System Devices and an Unknown device - see screenshot - which I can't figure out so haven't been able to locate drivers.

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

    Any advice very gratefully received!


    Speeds
