<< Solved >> HDMI / VGA Output not working on HP ProBook 450 G5

Firstly, I would like to thank @RehabMan for his guide on the HP ProBook series laptops:

[Guide] HP ProBook/EliteBook/Zbook using Clover UEFI hotpatch

Overview The purpose of this guide is to provide a step-by-step guide to installing Mojave, High Sierra, Sierra, El Capitan, or Yosemite on the ProBook/EliteBook/Zbook equipped with Intel graphics. Note: For Broadwell and Skylake hardware, you must install at least 10.11. Broadwell support in...

After following through all of the steps and with some additional tweaks (Sinetek-rtsx kext for PCI-E Card Reader & Layout 21 ID in SSDT for headphone jack), I've been able to get pretty much everything working, excluding WiFi & BT (I've purchased a Broadcom BCM94352Z and am currently waiting for it to arrive). I do have one problem though, which I can't seem to find a solution for. I am unable to get any external displays to connect to my Hack, neither through the HDMI and/or VGA port (Don't have the hardware to test the USB-C / DisplayPort currently).

I have tested both of the above mentioned ports under Ubuntu and they work perfectly, however MacOS doesn't seem to detect any external displays when I connect them. I have also tried booting with an external display connected, but to no avail, as only the internal display is detected.

I'm attaching my debug report to this post and would be really grateful if someone could assist me in resolving this issue, as I can't seem to find any other users who have reported this problem on this model of laptop and it's quite puzzling to me.

MacBookPro11,1 would be a better choice smbios

Actually 15,2 matches his hardware better.

Well, I didn't think it would be that simple. Changing the SMBIOS to 15,2 seems to fix both VGA & HDMI output. No way to test the HDMI-Audio, as the monitor can only connect to HDMI via a HDMI-DVI adapter, but regardless, thanks a lot.

Hi everyone,
I confirm that on my 450 G5 using MbP 15,2 fix VGA. I will test HDMI (both video and audio).
By now, after sleep my external VGA monitor loose the proper resolution and position. I usually have 1920x1080, with external monitor on the left and hack on my right. After sleep, the monitor goes to the right (for macOS) with a lower resolution (1152x864). If I want the correct one, I have to unplug+duplicate monitor+some other things that works randomly. So VGA is working, but with some issues..
