VGA through rpi pico - How many colors possible on border?

[Brocky]

still getting green?
its really a simple circuit it should work easily...
do you have an oscilloscope to check the inputs and outputs of the comparators, and then to the pico?

maybe the plug and wires out to the board are wired wrong at the 6 pin din youre plugging into the cpc?

I'm really stuck here.

can you take close pictures of the whole set-up? At least one of the full PCB and one that shows the pins of the monitor connector from the soldering side?
