Hi recently my laptop screen got damaged and now i have an external monitor and it worked for a while but now the damaged screen shows only black like it doesnt work at all and the laptop doesn’t recognize the external monitor and i do not know what to do pls help me thanks

Laptop screen will only work once it has been connected to an external monitor, even if that monitor is switched off

Having an issue whereby I cannot see or use the Laptop screen without first plugging it into an external monitor.

• 
  Upon Windows startup unconnected to any external monitor
  
  • 
    DELL opening logo can be seen on Laptop screen
    
  • 
    Screen goes black with backlight
    
  • 
    Mouse pointer can be seen onscreen if moved to the right, as though a second monitor is connected on the left hand side.
    
  • 
    Attempting to press enter and type in password in the correct order as though the screen was functional does not do anything
    
• 
  Upon connecting to an external monitor (even if switched off)
  
  • 
    Laptop screen will suddenly appear, all functionality restored
    
• 
  Upon disconnecting again from external monitor
  
  • 
    Laptop screen remains visible and functional
    
  • 
    Lock screen /unlock screen no problem
    
• 
  Upon shutting and opening the laptop lid
  
  • 
    Screen black with backlight, same results as windows startup, mouse pointer can be seen and moved as though a second screen is connected on the left
    
  • 
    No functionality until reconnected, even for a second, with an external monitor.
    

Troubleshooting:

• 
  Restarting multiple times, checking multiple display screen is not activated:

External monitor

Hi, my Aspire V15 laptop is connected to the Benq monitor with an HDMI cable. The system was working perfectly until the last Windows 10 update, but now the computer cannot detect the monitor. When I look at Display options only one screen is shown - the
laptop screen. Win + P does nothing.

Benq customer services say there has been no change to the monitor software which could explain this. They suggested that I update the graphics card and see if that helps. The NVIDIA Geforce 940M is up to date and I have just updated the Intel HD Graphics
5500, but still can detect only one screen.

Trouble shooting software on the laptop tells me that the setting for drivers was that they should not be updated: I have changed that to update automatically in future. My wife's computer uses an external monitor and it still works without a problem, but
she is not aware of having had a big Windows 10 update recently as I had

I haven't tried Safe Mode. How do I do that what should I look for and how might it help?

Thank you for your help.

Different resolution for laptop screen/external monitor?

Hey everyone,

I recently bought an external monitor for my laptop and I would like to use both of the screens in extended mode.

The problem is that my laptop's screen resolution is 1366x768 and the external monitor's resolution is 1440x900.
How do I change the resolution individually for each screen? I can change the external's resolution by using "second screen only" mode, but when in extended mode, I can only go with 1366x768. I tried searching on google, but with no luck.

Is there even a way to do this?

Thanks in advance.
