HDMI not working HP ZBook 15 G9

Issues & Assistance Unsupported hardware | Dual boot
1

Hello community,

The HDMI port doesn't work on my pc. It also got an USB-C port for dock and screens work with it. But I must use the HDMI port.

After some search, I found that VBT is exposing the HDMI port as a eDP.
Luckly, I found a quick patch from this forum : HP Zbook Power 15 G9 (i7-12800H) HDMI not detected (#8601) · Issues · drm / intel · GitLab
But I can't understand how to install it.

That is a kernel patch. Patching the kernel is a somewhat arduous and long-winded process. You need to clone the source for the kernel, apply the patch, then recompile the kernel afterward. It also looks like that kernel patch is specifically for linux-drm-tip kernel, so before you go too deep you'd have to confirm that your system will run on that kernel in the first place. You would also have to re-do the patch on every kernel upgrade.

This would be the relevant documentation to get started:

thank you for the answer, I learn a lot from it.

Unfortunately, drm-tip kernel doesn't work on my system (fresh), so I can't go further.

I have no choice than go back on cough windows cough

Hi there, by any chance, is your laptop’s HDMI port soldered to Nvidia GPU?

I had same problem with my Omen, and here is the "workaround " that I had to use

I hope this solves your issue.

Thank you

I tried this software. But the problem is not on "how the HDMI port is soldered ?" (on mine, it's an HDMI mux) but "how the bios shows video ports ?" and in my case, HP decides to show it as an eDP, I think it's for compatibility with USB-C port to use 3 screens

Thank for trying, I think you can manually close this ticket.
I don't believe that someone would take a colossal time to fix this for a too few amount of people, especially when it's "HP's fault".

Ohh, it’s issue with particularly HP Zbook lineup, and is with Linux in general.

Most probably, the driver issue.

Well, there are thousands of HP Zbook users using Linux.

HP will have to fix it sooner or later. Don’t worry.
