One last update, I haven't fully gone down this path yet, but while I started this project and delayed completing it for the past few years, there have been some very interesting boards which have come out which might make it possible to do eDP directly from a CPU instead of requiring a bridge IC to get me there.  One option I am exploring is using a Nvidia Jetson Nano to directly connect to an LCD, and to take it to the next level, it is possible to connect it directly to a 4k LCD, with 16.7M color vs the 262k color of the current 1080p screen I am using.  I am still planning on doing some 3d prints with the 1080p design for validation and effects, but I think a Gen2 of this design will include a much nicer 4k display, and cost lest in the long run, not needing the bridge and clock chips needed with this current design.
