Hey there, I'm new here and i need your help. Sorry for my bad english. It's a long time ago i've written a text.
My Laptop is a HP Elitebook 8560p with only the Radeon HD 6470m. Installed is Mavericks with Chameleon Bootloader I've tried many things but Screen won't work correctly. At this moment i work with vnc because my lcd leaves blank. With GraphicsEnabler=No The System say my Graphic Card has 3MB all Colors are correct but slow Performance. With GraphicsEnabler=Yes Framebuffer= for example Hoolock (the incorrect) the Colors seems to be inverted and the System say Graphic Card is ATI Radeon 6xxx With GraphicsEnabler=Yes without other changes the screen leaves Blank wirh Backlight on. At this time i've tried it with VNC.
The Systems show ATI Radeon HD6470M. With VNC are correct Colors and Size. The monitor is able to rotation. I've tried FixEDID but i also won't work. Have you any Idea to solve the Problem. I've read many things about that but i'm to new in Mac to unterstand all this things. Hey, Of Course i've read this Topic.
And many other topics. But i don't get any solution. If the Framebuffer select automatical it is Hydrilla.
With this configuration the boot end with black screen. So i've tested other Framebuffers and configurations in Clover 1: InjectEDID=Yes InjectATI=Yes FB=Lotus Ports=5 LoadVBios=Yes The screen appears with very stupid colors but correct Size. The Dsiplay named 'Integrated Display' with Resolution 1600x900 GraphicsCard named 'Ati Radeon 6xxx Series' wirh 1024 MB RAM.
We put the 700 MHz 6470M to the test against the 954 MHz 920M to find out which you should buy, the older AMD or the Nvidia.
2: Inject EDID=Yes InjectATI=Yes FB=Lotus Ports=5 LoadVBios=No The Screen appears wirh correct Colors but with a Size 1024x768. The Display named 'spiddisplay' wirh resolution 1024x768 The GraphicsCard named Correct 'Ati Radeon 6470 M' but wirh 3 MB RAM 3: Is the same i've wrote in the instructions. Any other framebuffer with LoadVBios=Yes end in black screen. Any other framebuffer without LoadVBios=Yes end wirh correct colors but false resolution and 3MB of RAM. Can you help me.
Helle And thank you for your time. I've tried about 3 weeks to patch the connector. Today i get the right settings ( i think ). The System boot and all is ok.
When loading (verbose) is finished the screen turns on and the Apple logo with the right colors appears. At this time it doesnt switch to the desktop and stay at the logo.
Do you have an Idea? When iam back home iam upload my rom decodes an patched framebuffer. Edit: The System is full loaded because i can control with vnc.
But the Laptop Display show the grey apple. The default Framebuffer loaded from the System was Hydrilla. I´ve patched the first line because it seem like an configuration for laptop. And i correct the other lines thats the hot plug id is not the same. Here the first line of the patched Framebuffer for my lvds: 01 Is that so right? Or can you help to patch correct?
I too have the same Graphics 6470M. I am currently on 10.10 with clover and I have used every method to try and enable graphics, and all fail.

I was able to put it to sleep by closing the lid.while still black screened with Iopmoea and Pithecia. At this point, I don't know what else to do. I tried Chameleon and i was able to achieve a whopping 4MB of video instead of the 3MB; however with Chameleon AMD 6470M is not recognized, but I was able to get my screen resulotion 1366 X 768. Looked great, but was laggy due to the 4MB video. Slice i know you are a busy person, but I am really stomped.
Any suggestions? Is the problem because the first connector is at connector index 0 instead of 1? It's not an option for me because my blacklight is on and the screen is activated but with wrong size and wrong colors but perhaps an option for you. And i read that duallink must be '0' Another question. Do you use the Probook Installer?
And you are sure that you have only the Ati and not as second the intel hd? I will re-patch. I did use that installer at first but it did me no good since the DSDT that is generated disables my AMD. I patched my own DSDT with rehabmans repository.

And yes I am sure. This is the Hp Elitebook 8460p with AMD 6470M only!
I do use the kext from that installer and they seem to work fine. Everything working for me except video.
LoadVBios=true InjectEDID=true Inject-ATI=true FB=your patched framebuffer As first try with this options and blacklight activation in dsdt or direct in clover. Perhaps your screen is full activate but your blacklight can be off Other i will post when i at home could you elaborate about backlit in DSDT and/or in glover?
I am not sure how to go about that OK, I boot with patched Elodea frame buffer and upon loading the screen is backlit without any image however. I close screen to put computer to sleep when i wake it up, scree is completely black but cpu is still running. I can't seem to figure this one out. Can you post your settings? Yea no problem. You gotta give me a few hours because I am currently at work.
I will post my whole EFI folder. In the mean time, the screen works beautifully. I tested VGA, which works but the colors are off and dark/ haven't tested DP. To get it working, I actually did a dual-link patch on my DSDT although my screen is 1366 x 768. It works with Lotus while other's fail.
EDID injections with my screens EDID = no tears and jaggy screen. Are you using PBI to install? If so be advised that every generated DSDT from that program disables Radeon.from my own experience that is. I got it too. But with Hydrilla.
Your right the PBI block the GPU. But with Full resolution and beautiful colors there are glitches. In Safari the Websites flicker very strong You patched your own DSDT? If you are using Hydrilla that is great. It won't work for me. To get the flicker and other glitches out, you have to inject EDID in Clover.
That will remove the gitters. Since Hydrilla has 5 ports, you might be getting VGA and so on and DisplayPort. Here is my EFI folder maybe it might help you. I am currently working on getting my wifi recognized and working. Did you get QE/CI??
Are you asking in general or are you asking me about the update to 10.10.1? I wasn't able to boot to desktop.more like i wasn't able to log into desktop to find out.

The spinning beach ball after password entry remained. If that is not what you were asking, then my apologies but yes I get QE/CI. And it sleeps and wakes perfectly. Couple things to do now such as getting brightness adjuster/control working besides that, and wifi.this install is complete. Everything is working!
