Dell mobile Precision 7510 Intel hd530, black screen

[Jake Lo]

are you sure you set DVMT variable 0x432 to 0x3?
See here under the Prerequisites.
The command to set for this particular model with EFI Shell is
setup_var 0x432 0x3
 
After that you should have full QE/CI on intel display when you enable
InjectIntel
set ig-platform-id = 0x191b0000

Hi

DVMT is set to 96mb i.e. 0x0432 0x3

QE/CI is there if inject intel is set to true and ig-platform-id = 0x191b0000

 

but internal laptop screen freezes at loading bar. OSX continues to boot and login screen appears on screen share and i see that QE/CI works.

Hi

 

got it solved. I was missing the IO kit patch. 

running good now.

 

any I idea, My bios Optimus switching goes off after every boot. I want to leave it enabled.

 

thanks

[Jake Lo]

Ahh, you failed to mention you have 4K LCD

 

The switchable graphics / Optimus getting disabled is known.

The patch for RTC doesn't seem to be working which is the purpose of the patch.

I had tried the Clover RTC patch and patching the kext manually, neither work so far.

Hi

Thanks, it worked perfectly.

 

And intel HD530 works as it should. 

[Jake Lo]

Do you have audio and HDMI / Displayport working?

[ss2sameer]

1. HDMI out works

2. HDMI audio out shows in preferences but no sound

3. Displayport doesn't work.

4. Sleep Doesn't work with intel HD530

 

note HDMI out is getting connected with NVIDIA M1000M

[Jake Lo]

Do you have full QE/CI with M1000M?
