Screen often does not turn on when pc boots

Often I have to reboot the pc before the screen gets any signal. I have no extra login manager installed, so maybe something with that. Curiously it worked with artix (dinit), which I had installed till recently.

Now go tell that to the owner :-)

Hi,
the owner of what? Sorry, I dont really get it.

Disregard ReDress' comments.

Do you also not get to see the bootloader or does the output initially produce a signal and then drops out?
Don't reboot w/ the power button - frenetically pressing ctrl+alt+del should™ do.
Then please post the complete system journal for the previous (bad) boot:

sudo journalctl -b | curl -s -H "Accept: application/json, */*" --upload-file - 'https://paste.c-net.org/'

No, I also dont see the bootloader.
Output of the journal command:
{"link":"DealingsCeasar","url":"https://paste.c-net.org/DealingsCeasar","delete_key":"ShtcioMTV9JYdhxq"}

Just the link is sufficient, you don't need to put the delete_key as well.

No, I also dont see the bootloader.

Do you get to see the UEFI boot screen and/or can you enter the UEFI settings?
Is this a HDMI output? Are any adapters involved? (HDMI - DP plugs etc count as adapter)

Since the screen sometimes behaves normal, its a little hard to tell, but out of 3 times I tried so far I got into the UEFI settings 2 times (but maybe I just didnt spam the button enough?) And no, no UEFI boot screen. Also, no adapters involved DP directly from graphics card to screen.

Ok, so UEFI works, bootloader doesn't.
What is your bootloader and how is it configured?
Edit #2:

The OP wrote:

So the bootloader is the EFI boot menu and that did not work reliably either…

Does it help (this will not affect the bootloader) to force the output to be enabled
https://www.kernel.org/doc/Documentation/fb/modedb.rst - see eg. also https://bbs.archlinux.org/viewtopic.php?id=314524

One more thing before:
Your GPU sits in 0000:0a:00.0 which is a rather uncommon bus address - are you sure this is the PEG slot?
(Consult your boards manual, usually closest to the CPU and also specially colored)

Edit: wrt the PCI slots

Aug 06 10:46:21 meinRechner kernel: nvme nvme0: pci function 0000:01:00.0
Aug 06 10:46:21 meinRechner kernel: nvme nvme0: failed to set APST feature (2)

that might be related.
