Hi Carlos,
Can you test with a LiveUSB ?
Best

LiveUSB of which distribution? 

Sorry I don’t know if you’re asking that. 

Oh, yes! Ubuntu 23 it's fine for testing

I've start with LiveUSB Ubuntu 23 and at the begining it dosen´t work. Then I go to settings and everytihnd was OK, it detects the monitor but not signal. Then I change the config to mirror and it works. I put it back in extend and it works. So, there is no hw problems. Must be something with the drivers. But I really dont know how to continue, there is a lot of information about configuring the two cards. I'm going to disable Nvidia in BIOS ans try only with the intel. 

I think I get a solution, the problem is solved in this way:

- If you detect an external connection to HDMI. Configure only this output turning off the laptop screen..

status_HDMI=$(cat /sys/class/drm/card0/*HDMI*/status)

if [ "${status_HDMI}" = "connected" ]; then
  xrandr --output HDMI-1 --auto --primary --output eDP-1 --off
	sleep 1
fi

I had a similar issue with Executive 14".

I was configuring Arch Linux Sway (Wayland).

After several hours of browsing, checking logs, and thinking that it could be related to drivers, it started to work in Sway configuration, and with the external monitor connected to the HDMI port, I configured the external monitor with its resolution and disabled the laptop screen.

Before I tried to configure only the external monitor as before, but it didn't work, the key was to disable the laptop screen. Once I did it, now it works fine even with the laptop screen enabled.
