I'm planning to upgrade the 1366x768 TN-Panel in my ES1-311 to a FHD IPS panel. Although I'm quite sure that the physical dimensions match, a FHD panel requires a two lane eDP cable.

ES1-311 Panel: N133BGE-EAB (http://www.panelook.com/N133BGE-EAB_Innolux_13.3_LCM_overview_23812.html)
Example for replacement: LP133WF2-SPL6 (http://www.panelook.com/modeldetail.php?id=31610)

Text on the ES1 cable:
WISTRON EA30BM EDP CABLE
450.03401.0001 REV A01

Does the eDP cable in the ES1-311 have 2 lanes?

    Hi Balatekie,

    thank you for your quick reply. The original TN panel is 1 lane which suggests the cable also being 1 lane.

    However, the pinout is the same for 1 or 2 lane eDP. A couple of forum posts on panel replacements talk about other laptops having a 1 lane screen but a 2 lane cable. So it is possible for the cable being 2 lane in the ES1-311. 

    I know this is a edgecase, but I still was hoping for experience with panel replacement in ES1-311 specifically. The problem is that I can't find any information about the cable despite having the part number.

    In any case, thank you for your reply.
