I read the no 18 bit on HDMI in these forums somewhere. I guess I should have dug deeper down that hole, my bad.What makes you assume 18-bit is not supported on HDMI?
Your driver needs to convert the data to DPi so question is which adapter do you use?
A TFP401 from TI is all that you need basically.https://www.adafruit.com/product/2218 is an off the shelf solution, You should be able to connect the output to https://www.adafruit.com/product/1932 and wire that to your display. The 2 LSBs of each color will not get connected (RGB0-1).
Your display should work with a standard VGA timing, so no special mode line should be needed.
Currently I was investigating just incorporating the VGA66 schematic onto my PCB and using a VGA input controller, but your solution seems far more elegant.
Thank you for getting me back on track
