[SOLVED] VGA & HDMI output on Lenovo Z70-80

Recommended Posts

I want to know How to get the VGA and HDMI output on the Lenovo Z70-80 laptop with Core i7-5500, my graphics card is Intel HD Graphics 5500 with macOS HS 10.13.6

 

I read several guides to do it, but it's for Intel HD Graphics 3000 and I tried to do it for my graphics card, looking for similar values and replace them.

 

Where we should patch the AppleIntelSNBGraphicsFB.kext file

 

A few small examples are here 01 02 03

 

In another site I found a different file to patch that is AppleIntelFramebufferCapri.kext, and I searched and replaced the values and tried it with my macOS but nothing. This guide here

 

And finally I tried this KextsToPatch in my config.plist file

 

Name: AppleIntelSNBGraphicsFB

Find: 01020400100700001007000005030000020000003000000002020500000004000007000000030400000004000009000000040600000004000009000000

Replace: 

01020300100700001007000005030000020000003000000006020000020000003000000002050000000800000700000000000000000000000000000000

commentary: HDMI + VGA

 

But nothing again ...

 

In my long adventure to try to make it work, I found different config.plist files to fix the functionality of my Intel HD 5500 graphics card, and I tried differents KextToPatch values, and with a bit of luck I found these values

 

Name: com.apple.driver.AppleGraphicsDevicePolicy

Search: BA050000 00

Replace: BA000000 00

Comment: prevent AGDP from loading

 

With the above values I can sync VGA & HDMI output automatically

 

VGA: In my ViewSonic VX1945wm  with 1440 x 900 res

HDMI: In Samsung TV UN32EH4500G with 1366 x 768 res (the worse resolution) and when I try to change to full HD I can but it has unfocused image, out of frame and with sound without volume control. My TV is  full HD native.

 

Please I need support from someone who could help me to fix this.

 

Thanks in advance.

 

PD. I attached my config.plist file and pictures

Erm... The fix is described in details above, in post #1! It works for the OP's Broadwell iGPU and computer but may not be applicable to other platforms and other iGPU generations. But feel free to give it a go, you never know...
