@GREYSTAR please don't PM me but write here.
 

The GTX 1070 does not work on M6700 and Windows, it might be working on linux but that's it.

P3200/4200/5200 were never tested in the M6700 so we have no idea if it could work, furthermore as far as I know those Px200 require to some soldering job to modify the card (soldering eeprom).
Finally an INTERNAL (eDP) 4K 120Hz indeed require at least a Pascal GPU (there is some vbios update for desktop Maxwell to get them running DP 1.3/1.4 but probably not available for laptop), if you want to plug an EXTERNAL 4k 120Hz you are out of luck, the M6700 is limited by the PS8330B IC (soldered on the board and not replaceable) only supporting DP 1.2 (and so 4k 60Hz).

 

Indeed @TruenoG7does require to flash the vbios made available in my earlier posts, the safest way is using a CH341A with a clip and the 1.8v adapter, using nvflash might be tricky.

i sorry about pm i will write here

i have the ch341a and soldering eeprom is not a difficult thing for me

the important is vbios ,i have no way to get it

the p4200/p5200 is high cost performance in my region .(about 140$ for p4200m; 242$ for p5200m)

i use display is b173zan03.3 with 3d display cable (QAR10_LVDS_CABLE_3D_2D DC02C002D00 REV:1.0)

m6700 edp is 4line but m6800 edp is only 2line so i use the m6700

 i wang change a good pascal gpu on my 6700

I'm very glad you could reply to my question
