I got a good deal on 2 RX 470 Mining Quad UEFI cards so i picked them up they have a hidden HDMI port nothing else you can access by removing the IO shield.
The guy who selled the card told me if i flash the bios it should work.
I flashed all the Sapphire RX 470 bioses i could find without success.

It seems like the Bios Flash was succesful GPU Z is showing all the right values but no screen like before.

Put the original Mining Bios back on it.
It clearly had an output for a reason, I assume not all mining set ups run headless and must have at least one display connected somewhere.
The original P/N does not show any display out put though so you may be out of luck.
