Windows 10: second monitor not displaying anything

I had a second monitor laying around and as I recently got a new keyboard decided to build a setup and bought the HADMI-VGA cable I needed. It has worked flawlessly for 3 days and today out of nowhere it stopped doing its job.
The thing is windows detects the monitor and the double monitor configuration shows and everything, but it stays with a black(in black) screen and nothing shows up, not even the cursor. Can someone help me?? thanks

Second monitor not detected after update

Hi Tom,

There are several reasons that could have caused the issue you are experiencing. One of these is the update you previously performed in Windows, either it was not configured properly by the system or the update components were corrupted. Kindly answer the
following questions for clarification:

• Have you tried updating the monitor and display drivers?
• Have you tried to use another user profile to check if the issue re-occurs?

Furthermore, we suggest that you add the other monitor manually. This is to ensure that the second monitor is still connected after the update. Here are the steps:

• Type connected devices and open Connected Devices on the
  Windows Search bar.
• Click Add devices.
• Select the Second screen.
• Pick one of the 3 options: Duplicate, Extend, and the Second screen only.
• The Duplicate option will duplicate the primary display to secondary display.
• The Extend option will unite two monitors so you can use them both as one.
• The Second screen only option will, obviously, disable primary and use only the secondary monitor.
• Once you’ve chosen the preferred mode, save changes.

We're looking forward to your response.

 

One Monitor running on a 2 monitor display, cant disable the second monitor. Help?

Hi,

If you can't access the Display settings, it means that it appears on the second monitor which you don't have. This happens if Windows is not back to the primary desktop.
