Sorry for the noob question, but where did you get the schematics from? I'm looking to put a 1440p or 4K panel in an NP8177 but I can't find the schematics for it to find out if it's eDP-only or eDP/LVDS like in the original post.
The model name is Sager NP8177/Clevo P670HS-G, or NP8176/Clevo P670HP6-G should also work cause it's the same laptop but with a GTX 1060 instead of GTX 1070, Sager NP8156/Clevo P650HP6-G is the 15.6" GTX 1060 model and Sager NP8157/Clevo P650HS-G is the 15.6" GTX 1070 model.
Clevo P670RS-G seems to be the Intel 6th-gen version of the board, but it still has a GTX 1070. The Sager rebrand of the P670RS-G is the NP8173, and the 15.6" version is P650RS-G or Sager NP8153. GTX 1060 versions are the Sager NP8172/Clevo P670RP6 (17.3") and Sager NP8152/Clevo P650RP6.
Hopefully one of those helps. My speciality is phone and computer repair, not laptop schematic hunting
