After an update to linux-6.5.3 my monitors went blank after grub. No error / no problem reported, X11 detected the monitors and they were turned on but stayed black (blank - the backlight was on). No monitor on console and no monitor on X11.
Downgraded to kernel 6.4.12-arch1-1 and everything works again.
The problem did not occur with another Philips Monitor but was there with Philips 242S.

Do you want help with the issue under 6.5.3 or are you content to stay on 6.4.12? If the former please post the full system journal for a boot with the issue and one without.

Sorry, just posted it in case someone faces the same issue and is happy with this workaround. I don't mind staying on 6.4.
