I've tried matching the wiring exactly as the smaller screen, still same issue, hub75b connector on both from what I can tell. Any hints or help anyone can provide?

Assuming the wiring hasn't changed between Pi models. I've created this wiring diagram as well since I was having a hard time translating between hub75 and the pi wiring, if it helps anyone else, great.\r\nMy wiring:\r\nhttps://imgur.com/QPGNjHv\r\n\r\nThanks again.\r\n"}}
