I use a PC with the integrated graphics of an i5-12400, but unfortunately when I try to install it, I only get a black screen after selecting "Try or install Zorin OS". The option with safe graphics works, though after installation I cannot boot the system. It would require me to edit the boot parameters and add nomodeset which is of course not useful in production use.
Can you please clarify what you mean in this statement? I am not sure I understand and it is a lot easier to try to be helpful if I have a reasonable understanding of the situation.
nomodeset is a kernel parameter which can be added (e.g. after quiet splash) by editing the configuration file of the grub boot loader by pressing the [e] button.
In that case, booting is possible - however, this will restrict me to 1024x768 which is not really useful. I assume that the same parameter is added when using the safe graphics option of the installer.
Ah that makes things clearer.
You can try removing the splash parameter entirely and see if that works (It does the trick for some.)
You can try nomodeset in combination with GRUB_GFXMODE= with the preferred resolution and refresh after the (=) sign. You may need to add GRUB_GFXPAYLOAD_LINUX=keep parameter as well on some devices.

Alright, let me try that out. Can I already set this parameters in the installer? Because I will do a new installation.

I am not actually sure... but since you can boot up and edit Grub, it should be fairly easy to do it that way - and more accurate for testing on a baremetal install.
I was so exhausted and planned a reinstallation, so already deleted it 
But it will not take long time.
Short question: I also noticed that I could not see my second monitor with nomodeset added. Is that normal?
You should be able to use both. More troubleshooting will be needed.
Installation complete. Removing splash didn't work, I only get this:
What hardware are you using?
Also, I get this error before GRUB loads:
That concerns me... To be honest, that looks like corrupted files in Root. That file should be Present.
This unfortunately also didn't work (resolution will be still 1024x768), I used it with nomodeset together:
nano /etc/default/grub
GRUB_GFXMODE=2560x1440x60
GRUB_GFXPAYLOAD_LINUX=keep
update-grub
For me it looks that Alder Lake GPUs are not really compatible with Linux 
About the missing file error message: Could it be because the partition is encrypted? GRUB though didn't complain about, so I wonder how that could be a problem. The file should be stored on the /boot partition, or not?
The file checks in the installation all passed, no errors.
Interesting! Can I install the newer kernel also if already installed or would you recommend a new installation? Which repository would I be required to add?
Thank you, I'll try that 
Does it make more sense to start from reverse, so 5.19, 5.18, ... instead of 5.16, 5.17 ... ?
I see, makes sense. I now tried 5.16 but it seems it wants libssl3 and libc6 >= 2.34.
EDIT: Wait, seems I need to remove the (unsuccessful?) installed kernel 5.16 first.
It seems the tutorial doesn't work any more. Installing libssl3 fails with following error:
root@office:~# apt install libssl3
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libssl3 : Depends: libc6 (>= 2.34) but 2.31-0ubuntu9.9 is to be installed
linux-headers-5.16.20-051620-generic : Depends: libc6 (>= 2.34) but 2.31-0ubuntu9.9 is to be installed
Alright! Installation of 5.16 was successful. However, booting only possible with nomodeset. I think I should also test 5.17 so.
Unbelievable. With 5.17 not only it worked immediately, booting is even faster. I immediately received 4K resolution and both screens were detected.
Shall I now remove the repo for the mainline installer? Will Zorin OS ask me for upgrading Gnome in future? Because you said it should not be upgraded.
Thank you so much!
I hope all will run stable, no freezes or so. Thank you very much 
I used the latest version of 5.17:
5.17.15-051715-generic
Yes, I'll keep that! The jammy repo I immediately removed after installing libssl3
