Rx 570 pink screen

[EliteMacx86]

This was it: ASUS AMD Radeon RX580 8GB 2048SP GDDR5 Graphics Video Card (DVI Single Port), I bought it on eBay and where I live we don't have much financial resources to buy computer equipment, I didn't pay attention to the description and only saw that it had a single DVI output when the card arrived, after 30 days of transit.

Ah, gotcha.

The problem installing MacOS was the BIOS, the one on the card was modified, I installed the BIOS from the RX 570, because the 580 is not 2048SP and is not supported for MacOS

Oh yes. Also, did you replace the GOP signature?

The reason for the pink screen is because, the VBIOS does not match the physical output of the card you have. You'll have to find a BIOS that matches closely the physical outputs on your card you will end up with no video output or pink screen.

The best approach is to edit the original VBIOS that came with the card, as it would contain the correct port configuration, memory timings, etc.

I just downloaded a ROM compatible with the lower model RX570 card, the RX580 VBIOS didn't work, but following your question, I'm going to change the original VBIOS and test it, it's very likely that's what you told me

I'm going to follow this tutorial:

VBIOS RX580 2048SP MACOS
