I'm having problems with my second screen, when I start the system both screens turn on but when Windos open the second screen turns off and goes black.
The screen works because I duplicated the screen, I also configured it as the main screen and it worked.
I already tried changing the HDMI cable and uninstalled the drivers from the screen (I don't know if I did it correctly).
I don't know if it's a driver problem or something else, I'm looking for possible answers.
Graphic chipset: Radeon RX 580 Series
