AMD Radeon HD 7670m and El Capitan (no HD4000)

Yes, My CPU is 3520M.
I check all of SMBIOS, always gradients problems.
I really do not understand what I messed up

edit: Maybe it's hardware, screen problem ? (i don't think so, but after all the things i tried.....)

I receive the same pc, but it's a i5, i put the ssd from the other hp, and it's working. The resolution is bigger, screen more efficient, so maybe it's a screen problem !
Thanks you for your time, and your EFI folder, it's working like a charm !
Tanks for all !

Glad to hear you!

Shouldn't be given up.
Maybe you generated the ssdt with wrong flag. ((beta) -w 3 or -c 3?)

Or

So, the first 8570p had an 1366x768 or 1600x900(LGDO258) or 1920x1080(LG LP156WF1) panel, because in config under Graphics/Dualink 0/1 is may caused the problem.?!
Pleasure.
