Laptop's LCD works, but not when its plugged into an external monitor?
The laptop’s LCD screen is working but, when an external monitor is plugged into it, it’s only showing on the external monitor. When trying to change the settings to extend the screen, it’s still only showing on the monitor and will revert to “Show Only on 2” in the display settings.
It started, but I managed to find a workaround where I turned the laptop on and then plugged the monitor in, and that was working fine for about a week or so but is no longer working.
What do I do to fix this?
Это хороший вопрос?
so does it still swap to the external monitor still work when plugged in?
