SUMMARY
I have a 2021 Asus Flow X13 with and Nvidia GPU and a AmD APU, it has an HDMI port, when i connect an external HDMI switch, everything works fine, both screens work up until i login into my user. 

After login only the laptop screen works, and on the display settings panel the external screen is constantly connecting and disconnecting, and the external screen doesn't display anything.

If the same screen is directly connected, everything works as expected and external screen works.

STEPS TO REPRODUCE
1. Boot computer
2. Log into User
3. External screen stops working the moment I enter my password

OBSERVED RESULT
External screen doesn't display anything and is constantly connecting and disconnecting on display settings panel.

EXPECTED RESULT
Screen just works
