Windows 10: Multiple NVidia Cards - Code 43 (Info Only) Solved

    Multiple NVidia Cards - Code 43 (Info Only)


    I thought I'd post this info here for anyone who has dual NVidia graphics cards but different models. (Mods: Not sure if you want this as a sticky?)

    NVidia have confirmed that they will support cards from 400 to 900 series but if you mix certain combinations, then the first to boot will be the only one to work - the second card will display a code 43 in device manager.

    Is there a fix for this? or any more information?

    I'm glad to finally see what my issue is but how do I resolve this?

    No fix yet, still awaiting a new driver...

    Don't think a new driver will help. It would be up to Microsoft to re-write how the WDDM 2.0 works, and seeing as it is also part of Direct X 12 I don't see that happening.

    I'm using 3 Monitors and it appears that 2 are using Nvidia Display adapter and 1 is using the Intel. Something I've noticed is if I plug in only the monitor which is using the Intel adapter until windows is all the way booted up then plug the other 2, all 3 monitors will function and both display adapters in device manager will be functioning properly. Then if i restart I'm back to the Intel one giving Code 43.

    The 2 Display Adapters that i have is,
    Intel(R) HD Graphics 4600
    Nvidia Quadro K1100M

    So i believe this can be fixed either by a driver or system update from Microsoft.

    That is interesting, and it almost fits my circumstances, except for my two nvidia cards work fine in Linux and worked perfectly in Win7, Win8, and Win8.1.
    The only driver that has worked for me so far is the 350.12 GTA driver, however even when using the KB3073930 tool to hide updates, MS shoves other ones down the pipe.
    I am just about convinced that the only way I can have three monitors again is to back to Win8.1.
    Thanks M$, well done.
