Hello,My laptop can't detect a second display. I have tried connecting it to TVs, others laptops, PS4, etc, ... and it never works with the exception of one specific TV.I connected it using an HDMI cable. All the ports are fine and I got a new cable because I thought the other one was faulty it wasn't.All drivers are installed and updated. I have AMD Radeon TM Graphics.

Laptop display does not detect itself

Hi,

I only have 1 computer (the laptop) and 1 external monitor. The laptop cannot detect its own screen.

So when I follow your steps, this is what happens:

• Go to Settings. (Done)
• Click on System. (Done)
• Under System, choose Display. (Done)
• Under Multiple displays, click on Duplicate these displays and apply. (Done)
• But then I undock my laptop and redock. Re-login, etc.
• Only the external display turns on. The laptop does not turn on its own display. In order to get the laptop display to wake up, I need to follow steps 1-4 again. The settign "Duplicate these displays" does not seem to be retained.
