    Try using CRU or the Nvidia drivers, iirc the mDP port should be connected to the dGPU instead of iGPU
    Also, intel drivers don't let you set custom res's anymore

    See with me having the 1070 which I’m using through SG mode I can only connect via the iGPU. That’s where I think I’m stuck.

    Yes I know, I believe the mDP port is dGPU only with a dGPU active at all

    What is the native refresh rate of the monitor you are trying to use?

    What I did on my M18xR2 to get to 85Hz was to flash the EDID of the monitor because native was 60Hz. This was the only way to bypass the intel limit.

    If you monitor has a native refresh rate of 100hz+ then it should show up. But if the resolution/refresh rate combo is too high for mDP 1.1 then it won't work.

    I think it’s 100Hz native overclockable to 120Hz

    Looks like 3440x1440 @ 100hz (120Hz overclockable)

    Unfortunately mDP only supports up to 3440x1440 @ 60Hz I believe so you won't be able to do 100hz even.

    This is a Optimus limitation. Your 980M SLI setup wouldn't have had this issue.
