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

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:
  
•

Monitor goes black

My external monitor loses connection with my laptop 3-4 times per week. First it goes to blue screen with no connection message, then it goes black. Sometimes the image returns in 1-3 minutes, often never without ctl-alt-del then signing in to my account.
Is this a computer video problem or possible virus?
