X1C Gen9 custom display: which 0.4-0.5mm adapter to use?
B140QAN06.T has 20682-040E-02 connector with 40 pins at 0.4mm pitch but, my mistake, the panel doesn't fit the top cover
B140QAN04.H has 20738-040E-02 connector with 40 pins at 0.4mm pitch and fits but still
cable: DC02C00N700 (from X1 Gen 9 MB to 40 pins, I'd guess 0.5mm pitch).
Problem: No adapter such as the one in the picture (which I bought and tried) seem to fit the screen (or the DC02C00N700)
according to this post, the official cable ends (panel side) with a 0.5mm pitch connector as the AUO B140QAN03.H has a 20765-040E-11A connector with 40 pins at 0.5mm pitch but the monitor I bought has 0.4mm pitch. Can anyone recommend the right adapter (or alternative cable from another thinkpad that uses same connector on MB side and 40pin 0.5mm on display side)?
Please, before answering: I am not asking which panel to use. I am asking which adapter to use.
Thanks.
