not quite the answer you want but you can work backwards to guesstimate
the connector the the screen is an 20455-040E-76 if you look at the datasheet its about
7.55 + (0.5* pin count)mm or 27.55mm
looking at frameworks marketplace page for the edp cable and using the IPEX connector as a ruler, in paint, I can add 6 and 1/5th ish IPEX connectors, 27.5 * 6.2 about 170.81mm, multiply by the “eyeball’n coefficient” which is about 5% and round half up, 170.81*0.95 = 162.2695, or about 162mm
I think at least…, I also did the same math for the wrong connector and got 124mm
