About DisplayPort lanes length

[mulfycrowh]

Hi.
Is it a problem if the tracks dedicated to DisplayPort lanes are about 45 cm long?
I have about 50 signals to drive from display connector to docking connector (Video + Touchscreen).
For sure, each lanes of differential pairs have the same length.
I only have 13 mm width for PCB on docking connector region, so I need several layers.
Please refer to the attached PCB drawing.
Thank you.

It may depend on devices, but I believe you can buy all the kind of cable length for display ports: https://www.amazon.com/s?k=display+p...f=nb_sb_noss_2

If cable can work, layout could also work just fine (when properly done).
