Laptop display question

Confusing statement! You want to change the display on your laptop that died?

Is that correct?

How do you know its the display that's bad?

Just google "how to change display on a acer 5745"

Should get you to step by step instructions. But first make sure its the display that's bad

• Go to Settings.
• Click on System.
• Under System, choose Display.
• Under Multiple displays, click on Duplicate these displays and apply.

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.
