Guide for enabling VGA, DVI, DP and HDMI in Intel HD4000 GPU

Recommended Posts

Hi Kenia,

Could you explain what string you used with chameleon? I've tried all combinations on 10.8.5 on an Latitude E6330, but with no luck. I'm not planning to migrate to 10.9, so your solution might do the trick.
 
regards,
Martijn

I've attached all the needed files.
It should do the trick...at least for me it did...
Unfortunately there's no solution for 10.9 except an Apple TV or external USB Graphic card.
Try with the files I posted and start your pc with the VGA cable already plugged in.
Regards.

how to find out my ig-platform-id correct?

 

I use this patch in my DSDT.

Method (_DSM, 4, NotSerialized)
            {
                Store (Package (0x0E)
                    {
                        "device-id", 
                        Buffer (0x04)
                        {
                             0x66, 0x01, 0x00, 0x00
                        }, 
                        "vendor-id", 
                        Buffer (0x04)
                        {
                             0x86, 0x80, 0x00, 0x00
                        }, 
                        "AAPL,snb-platform-id", 
                        Buffer (0x04)
                        {
                             0x00, 0x00, 0x01, 0x00
                        }, 
                        "AAPL,ig-platform-id", 
                        Buffer (0x04)
                        {
                             0x03, 0x00, 0x66, 0x01
                        }, 
                        "hda-gfx", 
                        Buffer (0x0A)
                        {
                            "onboard-2"
                        }, 
                        "layout-id", 
                        Buffer (0x04)
                        {
                             0x0C, 0x00, 0x00, 0x00
                        }, 
                        "AAPL00,DualLink", 
                        Buffer (0x04)
                        {
                             0x01, 0x00, 0x00, 0x00
                        }
                    }, Local0)
                DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                Return (Local0)

These are the existing values​​.

I understand that my LDVS would be embedded LCD.

but what is DP?
 
my notebook has 1 HDMI, 1 VGA and 1 LDVs.
what value should I use?

I have an Asus N56V with an Nvidia Optimus 630M + Intel HD 4000, and I have successfully gotten the Intel HD4000 loaded using either Chameleon kernel flags or DSDT edits, but for the life of me CANNOT seem to get the HDMI working no matter what I try.

 

I have tested using AAPL,ig-platform-id: 01660003 which detects the internal display (LVDS) without issue, but no other ports work.

 

I have successfully hex edited the AppleIntelCapriFB kext and tried every variation for using HDMI and nothing seems to work.  I even attempted at patching the kext for AAPL,ig-platform-id: 01660009 as this originally didn't support my internal LCD and I wanted to check if my hex edits were actually doing anything, and they DO since I managed to edit the lines related to this platform-id and got it to boot and use the internal display properly, but nothing I try seems to get the HDMI to work.

 

I am curious about testing the DVI port edits to see if maybe by some chance they would get the HDMI working.... just curious if anyone had any similar hardware?

 

I also have tried completely disabling the Nvidia 630M via DSDT edits (which worked) but this had no effect on getting any output from the HDMI.

 

About the throw in the towel on this..... just thought I'd open things to suggestions first :)
