Thanks for your response!
I found now a micro-HDMI-to-HDMI-Adapter in my cable box. Oddly, this way, HDMI works. So the original cable seems to habe an issue, but just with this screen. So for me that is a working solution.
Some extra notes:
I already am on the nightly build of the 2024-12-30. Also I already updated the firmware (EEPROM-Bootloader), it was on 2023-12-06.
Nevertheless not even the RPi Diagnostic Screen gets shown (Waited several minutes)!
Then I connected both RPi-HDMI outputs to the same screen, one on HDMI, the other on DVI. This way I can see the diagnostics page. interestingly, both EDID are shown as ok:
Below the decoded EDID data. The fact that it can be read out should be a prove that the communication between monitor and RPi id bidirectional, right?

Additional info:
The RPi5 and the Viewsonic monitor also work together with HDMI, if I boot first with using the DVI input and then switch over to the HDMI input. But after a restart, it is black again (even when I run another getedid create).

I have a working setup with a RPi3 and a ViewSonic VP2770-LED monitor (connected through HDMI). This works fine, but I want to switch to a RPi5.
So I setup a new SD-card for the RPi5 and booted it with the monitor connected. How ever the screen always stays black.
I know that the SD-card is setup correctly because if I use the RPi5 with a HDMI-DVI-Adapter, the monitor works correctly (obviously without sound). So there must be a difference in the way the RPi5 and the RPi3 handle the HDMI signal.
The micro-HDMI-to-HDMI cable also is ok because it works (with the RPi5) on a different monitor.
I already followed https://wiki.libreelec.tv/configuration/edid#generic-x86_64 and did a getedid create on both RPis and compared the bin file, they are identical.
