Windows 10: have external monitor - need to split screen to show one on monitor and one on laptop

I have attached a monitor to my laptop. I want to be able to move certain files to the monitor to view while continuing on the

laptop with a different file.


right now i see the same thing on both monitors.

:)

 

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:

connection problems External Monitor for laptop

If you're trying to use a wired external monitor is it connected to the laptop's HDMI output connector or the mini DisplayPort connector?

If you're using a wired external monitor and don't see any output, right-click on an empty spot on the Desktop and select Screen Resolution -> Detect

In addition, you may need to press the F7 key and select the mode in which the display will function. There are 4 modes:

• Disconnect (or Computer only): display only on the laptop's screen
• Duplicate: the same display on the laptop's screen and the external monitor
• Extend: extends the output so that you can drag things from one screen to the other
• Projector only (or Second Screen Only): displays only on the external monitor

Or are you trying to use wireless (Wi-Di or Miracast)?

 

Applications Not Opening on my External Monitor

I have a Toshiba Satellite laptop running Win 10. I have a Samsung external monitor attached via HDMI.

My background display and task bar DO appear on the external monitor, but when I open applications such as Outlook, Google Chrome, etc., they open on the laptop screen NOT on my external monitor.

I have shutdown both the laptop and external monitor and rebooted. The external monitor is listed in Device listing. I have the display setup for Extended Desktop and when I select Identify, it shows me 1 as the laptop and 2 as the external monitor.
I have unplugged both ends of the HDMI cable.

How do I get apps to open on my external monitor? Thanks for any assistance. Cheryl
