Windows 10: My laptop doesn't recognise its internal screen. External monitors work just fine.

The screen shows acer logo when turned on, then the backlights stay on but the screen is all black. I have a tv as external monitor and that works well Both Device Manager and Display Settings recognise the tv as main display and don't recognise any other monitor.PC is an Acer Nitro AN515-57.

Laptop not recognising internal monitor only external?

I usually work with 2 external monitors and have my laptop closed, however I am working out of office and need to use the laptop but the screen will not show up. The keyboard is fully functional but the display will not work. I have tried to change the display projection settings but it will only show when plugged into an external monitor and wont recognised the internal screen anymore?

 

Laptop not recognising internal monitor only external?

I have just had the problem where my laptop seemed to have lost the internal monitor. Turns out that the problem is something to do with Windows, not a hardware fault as so many responses to other reports have suggested.

In order to get the laptop monitor back I went through the following process:

- Reboot into safe mode on the external monitor

- in Device manager remove all monitors and the Display Adapter - make sure to view hidden devices

- shutdown laptop

- disconnect external monitor

- restart laptop and the internal monitor should start working

- reconnect external monitor and you should be able to use it as you expect

 

Surface Laptop 3 with external monitor

Hi All,

Has anyone come across an issue with an external monitor blacking out while connected to a Surface Laptop 3? I have the laptop connected to a widescreen laptop with the Surface Dock. Both work fine however, once every hour or so the external monitor blacks out and comes back.

I've completed the following:

• Updated laptop drivers and firmware
  • Updated monitor drivers
  • Swapped out monitor
