Ok . Thanks.
Just updated the system to 13.3
Updated drivers:

I followed the instructions of backlight implementation. Brightness works on Preferences Display Panel.
But I still have only one display working...
Here the problem report.
thanks

MacBookPro14,3 is a poor choice (it is dual-GPU). Use MacBookPro14,1 instead.

You mean I change symbios

I think post #44 is quite clear.

Changed to MacBookPro14,1. Nothing happened...

Any change requires new problem reporting files (you should know this by now).

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.
https://www.tonymacx86.com/threads/faq-read-first-laptop-frequent-questions.164990/
Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.

Also, you must provide a detailed description of the current problem.

I explain better.
Changed SIMBIOS to MacBookPro14,1.
I discovered that if I start the laptop with both display connected, I have only SAMSUNG.
If I start with built in display and then I connect SAMSUNG, I have both displays.
That' quite better than before.
May is it still Display override I made causing this issue?
Problem report files.

Typically, hotplug is required, as you have discovered.
