I have a samsung monitor that was working on another desktop computer, yesterday while I was listening music, the monitor turned off, it detect the HDMI but don't show my laptop screen. I already updated all the drivers and checked the resolution. If I press win + p, i can change the screen option and choose to show only the second screen while the laptop still works with the screen off.
The images show what is the problem.
