    Bang on. 1050 mxm would be a nice car. 980M performance on a 50w mxm A card!

    A 1050 has the performance of a 965M.

    That's a 1050 Ti. A "normal" 1050 has less performance.

    With other laptops I would be skeptical about it working due to other machines being far more picky with different MXM cards. The M15x has supported every single MXM 3.0 card since its release that has been tested. The Pascal cards except for lack of LVDS support I am very certain will work using the DP out on the laptop. My mod to convert this signal back to LVDS should also technically work and the GPU will be none the wiser.

    Also ssj92 you misread my OP. The mod is to convert DP to LVDS. Not the other way around.

    The challenge for M15x is lack space for the signal convertor board inside the chassis. M18x will have much more space but perhaps won't support Pascal at startup.

    Details on the mod? You have something planned? There is a 1070 going for the price of a 1060....would love to test in M18x and M15x.

    Nothing more than in the OP. That and a little bit of imagination :)

    Actually I think there's no need for eDP to LVDS board because M15x have already eDP route presented on the motherboard. It was just chosen not to be used. I've checked schematics and connections on the motherboard with multimeter. They're only few elements missing from the motherboard to make it work. Obviously eDP connector is'n presented and few more resistors, capacitors and inductors.

    What I understand from the Board View and motherboard itself, corresponding inductors L604 and resistors R898, R899 and so on (L605, L606...) should be chosen or to solder only inductors or only resistors because they occupies same places on the motherboard. So in theory it should be matter of soldering connector, few capacitors, few resistors and in the eDP lines itself: resistors or inductors. And off course eDP screen.

    Sounds fairly complicated however I have a spare M15x motherboard if you want to test it out :) currently fully functional.

    If this upgrade is feasible it will be a major success! I wonder if it is possible to change the cpu socket to support sandybridge ;)
