    Only using a single gpu now.

    Main tab
    integrated graphics , Intel ivy bridge
    discrete graphics 1, not detected
    discrete graphics 2, not detected

    second advanced tab, and under video configuration
    special features enabled
    primary display IGFX (I'm guessing as the new card not detected)

    OPTIONS UNDER VIDEO CONFIGURATION for primary display are

    Auto
    IGFX
    PEG
    PCI
    SG


    Trying PEG now,

    Ok so since it's set to iGFX it won't detect your NVidia GPU at all. If you set it to PEG and restart then it should switch over, hopefully. It may show up in the Device Manager as Microsoft Basic Display adapter until you install the correct driver

    Ahh there you go, SG will work for you then. I wasn't 100% on that one

    As I have the laptop still open i feel heat on the heat sink really good, also Microsoft basic display adapter is showing in device manager......nice

    So do I use nvidia experience to install drivers or avoid ?

    Firstly I would try to download directly from Nvidia and see if it's actually true that they have driver support now for the 900's. If it fails then you'll have to use a modded driver

    Well if PEG got you running on the 970M then it sounds like it worked.
    This will mean that the machine is only running on the Nvidia card so if you're running on the battery only, you won't get much life out of it before having to recharge. SG mode should allow the Intel graphics to take over when it doesn't need to use the Nvidia card. SG is usually disabled on the M18x because of SLI but I think it works when you're only using one card. I have my 1070 and Intel listed in Device Manager now that I no longer have SLI 780M's.

    EDIT: Other people may have better information on this though. I've only just swapped to the 1070 so I'm not sure how well the Optimus works now, or if it even does.

    Ahh I thought it would be an older driver. I came across something similar last week with a guy on another forum. It was a 2015 driver as well. I think if you try to get a recent one from Nvidia it will fail.

    If you're happy as you are then you can just leave it. If you want to try to get a recent driver then you may want to learn how to mod a driver. It's actually not hard and we can help.
