See the schematic on page 30,17.
8 LVDS_EDP_TX lines (JLVDS1) connect to MXM_EDP_TX via 8 2@capacitors, not connect to SW_LVDS_B because 1@resistors not exist on QHD edition. MXM_EDP_TX come from DP_D of MXM card.
The DRIVER cannot open DP_D or open it as eDP. Driving eDP also requires MXM_ENVDD, MXM_PANEL_BKEN....
Hope it works.
