Here. Although as I said in a previous post, FixDisplay is needed in order to make the graphics card work. Without it, I'm left with 7MB of video memory.

Actually, Oland framebuffer loads, however, no acceleration.
Clover/FixDisplay and WhateverGreen do the same thing and may cause a conflict
Experiment
a. remove WhateverGreen.kext
b. set config.plist/ACPI/DSDT/Fixes/Yes
c. install EFI/CLOVER/ACPI/patched/ssdt_hdmi-amd-default-P0P1.zip
d. add anything else required for recognized graphics

Restart and reply with files.

Here you go.
Graphics card now shows as "ATI Radeon HD 7xxx 2048 MB", acceleration is enabled.

ALSO, ran the touch command, here is the unexpected new output:

something is apparently wrong now, maybe due to all the ACPI fixes being off (except FixDisplay obviously)?

config.plist/Graphics/FBName/Oland does not exist in AMD7000Controller.kext, remove

Feel free to do the tests to figure out which is required, unlikely the cause

AppleDataSetManagement.kext

trimforce? Search works

Fix config.plist, restart, reply with new files

trimforce?

Yes, enabled trimforce. So that's what causes the message...
But more importantly:

config.plist/Graphics/FBName/Oland does not exist in AMD7000Controller.kext, remove

Removed, got a black screen upon restart.
Changed config.plist again using another computer, restored Oland > still black screen, can't get to the desktop.

Puzzled.

Yeah I'm not concerned, and I didn't ignore that recommendation. Just puzzled!

I could edit out the FakeID which I'm sure would let me get to the desktop with the unknown display adapter with 7MB. What would I do after booting the installer anyway?

I'm very grateful for all the help!!
I'll report back soon. I'm on Sierra btw

So all along, the last black screen problem seemed like it was just the graphic card that couldn't be initialized, or maybe the HDMI port- it all went blank after "DSMOS has arrived", but it didn't look like the system had froze or the boot had hung.
Turns out, rebooting with a monitor attached (DVI) gets me to the desktop just fine. Even the actual gfx card model is recognized.
Connecting the HDMI cable makes the DVI monitor resolution change to 1080p, as the preferences are set to "mirroring", but no signal is sent through it to the HDMI TV. Needless to say, no HDMI audio interface is present.

Files are attached.

Remark:
- I see in the last stages of the bootlog that the video port number is set to 5, while the graphics card has 3 (DVI, HDMI, VGA)...

Expected, config.plist/Devices/FakeID/ATI/0x67981002 is working and the Futomaki framebuffer is loading, likely, Clover default:

I don't know if I understand correctly, but you're saying that there's a chance I can make it work by following one of the guides to patch the framebuffer?
I'll try again from scratch then, the last thing I tried to do before coming to get help was following the first of the three guides mentioned in the first post.

NOTE: editing framebuffer name in Clover back to the "invalid argument" Oland makes the HDMI port work again. Can this be relevant in any way?
