Enable VGA Display Output for External Monitor #1

Open msakthiganesh opened 2 years ago

msakthiganesh commented 2 years ago

Hi,

I was finally able to install macOS Big Sur on my HP Zbook 15 G1 with slight modifications in the config file! Thank you so much!

But, I'm unable to use my external monitor using VGA (as Zbook 15 G1 only has a VGA port and no HDMI port), is there a possible fix to enable VGA support?

Thanks!

Hello!

Unfortunately, as I understood from OpenCore documentation VGA is unsuported on macOS 10.8 and newer if you have CPU prior to Skylake:

Note: VGA on Skylake and newer are DisplayPorts internally and so are supported by macOS

However, I found one link that may be helpful for you.

I don't remember if VGA works in my system with this config, but I will check later. Anyway, it most likely won't help you as VGA on our systems probably works internally differently.

But thanks a lot for pointing out! Hope you will manage it to work!

Hi Julian!

Thanks for the help. Unfortunately, my Zbook 15 G1 runs on i7-4700MQ (Haswell). I tried the config specified in the Reddit post but it didn't seem to make any difference. Attached screenshot of my current config.plist DeviceProperties/Add.

My laptop also has a Quadro K2100M discrete graphics. Have you stumbled upon any way we can use discrete graphics to enable VGA Support/enable discrete graphics with hardware acceleration? As of now, Intel HD Graphics 530 is driving graphics with acceleration.

Thanks in advance!
