Windows 10: Windows decides it wont display to my second Monitor, why?

So one day randomly my second monitor starting flickering, eventually not displaying at all. Now I know my monitor is ok because when I restart my pc, it displays to my second monitor the bootup screen before switching back to my main monitor. This would mean the connection is ok, the screen is ok. However after booting up and trying to switch my the secondary, extend to my secondary, or try to display to it in any way at all. Windows will not display to this monitor. What could be causing this?I'm using a Geforce GTX 1650 Graphics card

:)

 

Windows won't detect by second display.

I have my monitor and TV connected to my GPU. In Display Settings, under Rearrange your displays I have the 2nd highlighted. Clicking the Detect button will render: Code:

windows Can't detect my second monitor

Hi Max,

Thank you for posting your query in Microsoft Community.

I understand that you are having a tough time working on the computer.

I will certainly help you to resolve the issue.

• 
  What happens when you try to connect the second monitor?
  
• 
  Do you receive any error code/message?
  
• 
  Have you tried to connect the second monitor on a different port?
  

I suggest you to connect second display using a different port available on your PC and check if the second display works. If second display works in other port, then the possible cause for this issue may be discrete video card driver.
