Windows 10: Multiple monitors connected to a laptop

Hello,Because my work issued laptop is a 12 inch display, I want to connect 2 monitors to it. I purchased a HDMI display splitter, but the 2 monitors are displaying the same screen. I want one monitor to show what is on the laptop. My laptop only has one HDMI port and the USB ports are used for my headset, wireless mouse and keyboard. Help!

:)

 

i have a problem to connect 2 monitors.

Hi Ron,

Thank you for posting your query in Microsoft Community.

• What changes did you make in the BIOS? As making the changes in the BIOS is only recommended by Microsoft if done by the manufacturer.
  

• How are you connecting to the 2nd monitor?

I suggest you to follow the steps from this article below:

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:
  
•
