The LCD had immediately a blue hue, instead of B&W or color, so started looking at the DB15 pinout, and discovered that only blue was wired on pin 9 and 13 for blue ground, no other color.
Yeah, I can see from your pics that only one wire is a heavier co-ax cable. RGB and dedicated ground lines are commonly co-ax or at least twisted pair. I wonder if you split the blue signal out to run R&G at the same level it will turn your blue hued display into Monochrome? Might need line drivers to do it right, but I'd
almost bet it'll work. If it's a blue background tint, that makes me wonder if the background would be a uniform gray level instead of white? Is the text displayed as a really dark blue or black?
. . . the connector on the board is also DB15, but is not following the usual wiring (in other words cannot plug the display directly for a test)
DA-15, DB is the 25pin D-Shell designation, the "B" is now a generic designation for all sizes in common usage. [

Will have to do another test, will probably be able to output greyscale...
What are the copyright dates on the card? I can't imagine anyone bothering to design an SE/30 specific card that wasn't grayscale capable.
