    Threw my 1060 in my m15x before i put it in my m17x to see what would happen. The system posted and I could navigate the bios(by sound) but the screen was black. I tried connecting to an external monitor and It didnt output, but I didnt have the heatsink on the laptop so I didn't try too many things. If anyone has any ideas they want me to try write them down and Ill be happy to test them out.

    It's important to tell us what M15X it is. I supsect your M15x is an LVDS machine, hence acting like this.

    Better than what I got with my zotac 1070 + m15x, the "internal edp to lvds converter" must be inop or just dummy option

    Well, then there is your answer. The card doesn't support LVDS, since your M15x is an LVDS machine it won't work.

    Im not asking for it to work, Its already working in the machine I bought it for. I thought id try it in here as noone else had tried it, and it posted compared to the 1070. If the system didnt detect the gpu it wouldnt post, which means it has to be detecting the 1060 in some form.
    I think if the missing EDP connector was soldered on + an EDP panel installed you could get it to work. The X rev motherboard would be the far easier option but it doesnt seem like that is in supply anywhere

    Uhm that is not correct. A system should post even if it cannot read the GPU. If anything the GTX 1070 is weird for not posting at all.

    Also just because it can read the GPU doesn't mean it can use eDP signals. You won't ever get a picture on your screen unless you get some kind of hardware mod going that will translate LVDS to eDP, which if I remember, someone here did.

    Nope, the m15x needs to detect a GPU to post.
