Intel HD4000 and Radeon R7 250x (HD7000) simultaneously

[naquaada]

Hello,

 

recently I got an Asus PA32QCV 6k monitor. It's great, but this monitor wasn't made for user who sometime need to go into BIOS or open the boot menu. It takes endlessly until it shows an image.

 

So I wanted to use the Intel HD4000 for an additional display with is starting faster. The other card is a Sapphire GPRO 4200 which uses Cape Verde Pro. The card is working fine, but can only use 4K. On my Gigabyte Z77M-D3H with a Core i7 3770S I'm actually using Mavericks and Mojave, Monterey should follow. I'm using Clover in Legacy BIOS mode, every component is working. USB3 isn't working in full speed, but that's a minor issue. To avoid conflicts I have all kexts in S/L/E. No kexts in Clover. Mojave is installed on an HFS+ partition.

 

On Mojave I got a working GPRO 4200, the HD4000 is just showing the text from the boot sequence, no macOS display. But it is the main display, the GPRO 4200 screen has no menu bar or Dock. Mavericks crashes at boot if IntelFramebufferCapri.kext is installed. If I remove it, I have working dual monitor, but the HD4000 has no QE/CI, visible on the grey menu bar.

 

The HD4000 is connected to IGFX, the GPRO 4200 at PEG0, PEGP, GFX0, depending on the Clover settings. So I guess the problem is either in AppleIntelFramebufferCapri or the display name settings.

 

Here's the Clover plist. I also added a photo with the Mavericks crash at boot.
