    Hi!
    I recently bought a DVI cable to plug my external LG monitor to my laptop to run nVidia's DualView (stretch format) across the two monitors. I'm using a beta driver (169.04 from laptopvideo2go.com), and when I enter nVidia control panel and go into the setup additional monitors tab, it only lets me choose "choose only ONE monitor". So I did that just to test that my monitor was plugged in right, and it worked. So I KNOW that my monitor is working and is being recognized by Vista. But when going into display settings byt right clicking on my desktop, it also only recognizes 1 monitor. Is it my beta display driver messing my Vista up? Or what could it be?
    Any help would be greatly appreciated :)

    Thank you

    for drivers to work properly in vista i'm pretty sure you have to have signed drivers, since it's beta are you sure they are signed?

    They aren't signed. So it HAS to be signed drivers for the dual monitor to work?

    I solved it now. Just had to reinstall the driver. It doesn't have to be signed though.
