iM 4,1-14,4 2011 iMac Graphics Card Upgrade

[Shnite]

AMD FirePro S7100X is mxm card gpu and edp is embedded displayport (like a displayport) is video output (for what i know) for laptops. I want to ask anyone here which vbios is the one that have video output/edp support. Because I saw a 2 year old post in reddit of about the gpu and someone posted this year, 11 months ago saying a modded vbios for mac have that edp enable. I own that gpu and see 3 files in this website. s7100x_imac, gop-lvtma, and s7100x_6939_imac. I have laptop I'm experimenting with some 2 gpus but currently don't have a screen with edp but lvds screen installed, my main laptop have screen edp installed but I prefer avoid disassemble it if possible to see which is it.

Tested systems:
- iMac12,2: sleep/wake broken - black screen on cold boot needs PRAM reset each time


Known problems:
- does not run reliably in the iMac12,2

As I stated - I have a 12,2. So this ain’t the best card.
