No HDMI detection with HP ZBook Power 15.6 inch G10 Mobile Workstation PC with Ubuntu 20.04

When I check the BIOS, I can see the following.

Product Name : HP ZBook Power 15.6 inch G10 Mobile Workstation PC
Processor 1 : 13th Gen Intel(R) Core™ i9-13900H
Memory Size : 65536 MB
System BIOS : V97 Ver.01.02.01 08/14/2023

What I try.

  1. BIOS → Advanced → Built-In Device Options → Graphics → UMA Graphcs
    → HDMI doesn’t detected in Ubuntu 20.04

  2. BIOS → Advanced → Built-In Device Options → Graphics → Hybrid Graphcs
    → HDMI doesn’t detected in Ubuntu 20.04

$ uname -a
Linux 5.15.0-89-generic #99~20.04.1-Ubuntu SMP Thu Nov 2 15:16:47 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

When I installed Windows 10, I can see the Graphic driver “nVidia RTX 3000 Ada Generation Laptop GPU”

How can I fix the HDMI connection problem?
please help me.

Hi there @robin.kim and welcome to the NVIDIA developer forums.

In the BIOS leave the stting on “Hybrid Graphics”.

Then the first thing to check is if the NVIDIA driver is installed correctly. Does the command sudo nvidia-smi give you proper output?

The next step would be run nvidia-settings and check if you can see “PRIME profiles”, select either NVIDIA Performance Mode or On-Demand, both should work. Preferably Performance Mode. Then reboot.

If that still does not help I recommend checking out the dedicated Linux category here in the forums.

Thanks!

Thank you for your help.

This is my condition now.

$ sudo nvidia-smi

and when I try nvidia-settings → “PRIME profiles”, I was On-Demand but it doesn’t work.
Also I try to change “PRIME profiles” to Performance Mode but kernel doesn’t boot up anymore.

Hi,

I can see the description like.

OK, the issue is fixed here if I change some related BIOS setting: Advanced > Built-In Device Options ⇒ Graphics: [Discrete Graphics] # Instead of “auto” Although the laptop has only one video card (nvidia), the “auto” value here was problematic. With “Discrete Graphics” HDMI output works just…

but in my case I don’t have “Discrete Graphics” only have “UMA Graphcs”, “Hybrid Graphics”

BIOS → Advanced → Built-In Device Options → Graphics → [SELECT]

How can I fix this problem?
Is this BIOS setup issue?

Robin

I have heard HP ZBook Power G10 Workstation only tested Ubuntu 22.04.3(x84_64).
and it doesn’t support External HDMI port 2.1 in Ubuntu 22.04.3 now.

Could it work with an older version of Ubuntu?
