    It was quite a while ago, and I failed to mention the exact setup, but I think it was a msi 1070 vBIOS flashed Zotac 1070 stock DC EDID that runs fine under lubuntu*. Both my displays were recognized properly (the DC and the ZR30w). So I'm more towards that the driver doesn't know how to deal with this DP to 10bit LVDS awkwardness, or something among these lines. I have no idea where the driver gets confused, but I think that you can scratch the panel as I tried flashing it with DP EDID (custom @t456 ), instead of unknown (default). So if @t456, or anyone else for that matter, knows if there's anything special in the driver that he has used and if we can apply it under Windows, that would be awesome.

    * The utility that @t456 has made for flashing EDIDs

    BTW Do you take in mind Optimus/nonOptimus mode while modifying drivers? I haven't, so I'll try something again.

    I don't know if it's a good new but my Zotac GTX 1080 (never seen working before, I bought it as non tested/not working) is recognized by the M6700, I can install drivers but the card is in code 43, it seems to have a wrong vbios. The card isn't recognized by GPU-Z until the drivers were installed
    If it's working there are a few modification to make in the M6700, starting by removing the RJ45, then modifying CPU and GPU heatsink and might need a little bit of modification of the flex cable of the keyboard (the card seems to be "blocking" the cable by 1 or 2mm)

    You'll need to figure out a way to give the card more power as well

    I just need to solder some wire directly from the power supply otherwise it would be limited to 130w.
    But sadly I think the card is not working, GPU-Z couldn't dump the vbios, I tried with different vbios, even with the original from zotac, it made me think that the core is problematic.
    I forgot to mention but of course I use external display (VGA) with the iGP, the eDP is just power up but nothing appear on the screen

    Do you have an EEPROM programmer? if so you might be able to read the vBIOS by power it up with 1.8V voltage.

    Also, It's better to limit the power of the card. GTX 980m has already fried two of my M6700 motherboards

    Yes I already tried few vbios (not all) with external programmer with no luck, core and mem voltage seems ok.
    I might try to reflow the card a little.
    To be clear, what you I except if the gpu is not compatible with the M6700 when optimus is running (at least the igp is working in order to display something) ? Like stuck at boot ? Code 43 ? Other code ? I never tried not compatible card with my M6700.
    Also, if the modded drivers are not using the good "GTX 1080" it might cause code 43?

    I never ran into code 43. I'll tell you that when I had a Pascal card with "incompatible" vBIOS in my M6700, the symptom was, I could boot to the BIOS and all of the BIOS screens were fine but it would hang at OS boot no matter what I tried. (Legacy, UEFI, Windows, Linux, MS-DOS, all the same; hang at boot.) @iieeann ran into this exact same thing when he tried P5000 in the M6700 before we found the good vBIOS. That's not what you are hitting...
