DVI not working on extended monitor with Surface Book docking station

I recently purchased a Surface Book and docking station to go along with it. When extending the display to an external screen via the docking station, the VGA works fine, but not the DVI. If I connect the DVI directly to the Surface Book, it works fine,
but not with the docking station. I've tried changing the settings on my screen, but it will not switch from D-SUB to DVI. When connected by DVI through the docking station, it appears that it recognizes that the external screen is there; it just doesn't
display anything. I'm running Windows 10. Help!!

Hi,



Thank you for posting your query in Microsoft Community.



I understand your concern and will assist you to resolve this issue.

I suggest you to follow the steps below and check if it helps.

• 
  Make sure the power light for the docking station is on
  
• 
  Make sure the monitor is getting power
  
• 
  Make sure the cable is connected properly to the monitor
  
• 
  Unplug and reconnect the Mini-DVI adapter on the back of your docking station
  
• 
  Try flipping the connector for the adapter over (turns out some adapters can go in upside-down)
  
• 
  Take the Surface out of the docking station then put it back in
  
  
  

Hope this helps. If the issue remains unresolved, please get back to us and we would be happy to help.

 

External display with laptop and docking station

I have a Lenovo T440p laptop and docking station with a Dell external monitor. When I am using my laptop in the docking station I use both screens and select "extend this display" in the display settings to activate the external monitor. Heres my problem.
When I remove my laptop from the docking station it reverts to using one or the other displays when returned to the docking station, meaning it may be my laptop or it may be my external monitor. Windows seems to decide on its own which one I get to use so
I have to go into display settings nearly every time and select extend these displays to use both monitors. Its becoming time consuming and annoying. Why wont it remember that I am using 2 displays. I am running windows 10. I have asked our IT guys to fix
it but after weeks of asking and not getting any results from what they try a have given up hope. I had a different laptop, same brand and model that didnt display this behavior when returned to the docking station.
