Nvidia RTX 2060 mobile recognized but no signal in Ubuntu 21.04 nor 20.04

Asked by oscarsalvador24

Hi there!
I have been using Ubuntu 20.04 for a while and my secondary HDMI monitor was always recognized but never displayed any signal.
I have made some searches, and tried to update or downgrade the nvidia drivers package from 450 to 470 without any help.
Also changed to Noveau drivers and also no signal
I also upgraded Ubuntu to 21.04, no help.
I would like some guidance in how to continue. Maybe it is a bug? Should I report? Maybe I am doing something wrong?

A previous post by me was expired after 15 days as I was asked for some questions but never answered due to several issues i Had

The laptop is an Asus ROG model GU502LV-AZ130T

Please, if any other information is required, just ask
Thanks

Have you tried pressing the key marked with "F9"? It seems to be a switch to how video is output.

When I changed with F9, both screens turns black, and when pressed again, the laptop screen becames active again

But I do not want to have different screens and switch, I want to have both qorking at the same time and to clone or extend the desktop
