Tested your templates and they work fine on my card VisionTek AMD Radeon HD 7970 updated guide. The real trick is the code construction.
The problem remains in Post #1, specifically
Now we can simplify this process by using this set based on your connectors.
LVDS 02000000 40000000 08010000 00000000 + (add your code construction) 00000000
VGA 10000000 10000000 00010000 00000000 + (add your code construction) 00000000
DP 00040000 04030000 00010000 00000000 + (add your code construction) 00000000
DVI-SL 00020000 04020000 00010000 00000000 + (add your code construction) 00000000
DVI-DL 04000000 14020000 00010000 00000000 + (add your code construction) 00000000
HDMI 00080000 00020000 00010000 00000000 + (add your code construction) 00000000
The above connector control flags change
AMD60000Controller and newer:
hdmi: 00080000 04020000 ... (i.e., Duckweed)

AMD70000Controller and newer:
lvds: 02000000 00010000 ... (i.e., Exmoor)

Oh god, this is too much work lol. I'll just pray that clvoer devs will automate this in future clover builds. In the meantime I can boot from a clover which doesnt use UEFI...

Too much work? How? I made a template that can be used for simple patch construction in the guide. If you prefer a need to do nothing approach Apple sells Macs everyday.

Not likely this will happen too many graphics configurations to have to test. Now I have been thinking about writing a script that will generate the patch for you, I would likely need to employ the help of folks like @toleda and @RehabMan, but time is always a struggle to find. I hardly had time to write the guide.

I have Intel i3-2100 built on z68 chipset with Asus 7750 from AMD.
I am running on High Sierra.

I have tried Lilu+WhateverGreen, which seems to be working, but performance is limited when it comes to games.
I noticed that I am not able to see my GPU in HWmonitor, so I decided to try the framebuffer guide.

Is this possible for HDMI connectivity?
I have tried some framebuffers from AMD7000Controller (Aji, Namako) but all of them resulted in black screen with monitor off.

These are the codes I have constructed, are they correct?

I need problem reporting files mentioned in the guide right before the credits to help you

lol, they dont offer a product which would fit my needs. they only have all-in-ones and a ridicuously overpriced macpro... Also, there is an easy DSDT patch on the other forum, which fixes the blackscreen issue and deprecates whatevergreen, and I'm hopeful they'll add it to clover soon.

Also, DPCIManager is tagged as malware on sourceforge, so I dont have the tools to do it..

Yeah I've read the post you mentioned and plan on adding it to my guide, Mieze's work on that BAR2 vs BAR5 is outstanding work. I can assure you DPCIManager isn't malware it was developed by one of the Mods here at @tonymacx86 named @SJ_UnderWater who also developed MaciASL the program we use to compile our DSDTs, who also developed IOJones. Besides you get obtain your rom file from windows with GPUZ and a google search. Now I doubt Slice will be adding the DSDT patch to clover. But hey he might. The idea here isn't to be looking for quick fixes. But to learn about the OS, and how it can function on regular PC hardware. Now I ask you please don't spam my thread with nonsense. If you need help there are plenty of folks here willing to help you with this method. But we don't need to be wasting time on nonsense. All replies to this thread need to either asking for help or providing feedback with findings to improve the guide for others.
