Display issue when booting with HDMI present

[WhatNot911]

OpenMandriva version: ROME plasma6.x11 x86_64 build 3522

Describe the bug:
Launching Mandriva as live os from a USB with HDMI cord plugged into laptop just stops at some point. I have two monitors - one is on the laptop and a separate one, connected via HDMI, so when I choose to launch the os as Live OS the screen shows some text and then just stays black without mouse or anything. When I turn off the laptop text comes back but then it shuts down as it should. I have to remove HDMI and then wait untill it boots in and THEN plug it back for two monitors to work.

Hardware used:
MSI PULSE GL76 gaming laptop
Hartens MT-27ECM monitor
Generic 32GB USB flash drive

We will need a video card manufacturer. My suspicion is you are using an nvidia card but we need to know which one. nouveau can have problems with multi head configurations sometimes. If you have a hybrid setup with more than one graphics adapter, then it may need to be ran single until the nvidia driver is loaded.

My laptop ineed has an NVIDIA GeForce RTX 3060 Laptop GPU.

The CPU (12th Gen Intel(R) Core(TM) i5-12500H - 3.10 GHz) also is equipped with Inter(R) Iris(R) Xe Graphics (which makes it an APU I suppose).

Make sure you use the nvidia driver once you have installed it, which you can install in the Welcome screen. While using the live install disk, unplug the HDMI before booting. You can see if it will work if you hot plug the cable after you get to the desktop, but I wouldn't worry about multi head working from the installer disk. We provide nouveau as the default both because it is open source and because there will still be legal restrictions to provide the vendor branded driver.

As I wrote above this is exactly the behaviour that I'm experiencing.

I suppose this behaviour "comes with the territory" according to your response, correct? Oh well then. I guess it's okay then. Maybe some kind of warning would be appropriate in the installation guide then? Thanks for your time.
