Windows 10: Dual monitor not working post Windows 10 Update 10-21-19

I run 3 monitors on my HP PC. Main is connected directly to my PC. The other two are connected to VGA to USB converters. They are connected to PC.

Windows updated on 10-21-19.

IMMEDIATELY the next morning, my two "extra" monitors were blank. All monitors checked. They are fine. Connections checked. Converters checked.

Hardware is fine. (Plugged each monitor directly to pc, they are working!) This is a Windows issue. I had to do system restore, and everything was fine. Unfortunately, Windows knows my needs better than I do, and updated itself that evening, and the next morning, I had to do another restore past the point of update. This windows update does not play well with my converters. I am very frustrated.

I am now unable to restore past this nightmare, and have two monitors that are essentially paperweights on my desk.

Looking for any help at all.

Laura-from 3 to 2-because this build hates me.

Windows 10 Update - Now my dual monitors do not work

Hi,





One of the possible reasons why Windows 10 was unable to detect your dual monitor is an outdated or incompatible graphics driver. To best address your concern, we need you to answer the following questions:

• Which Windows 10 build are you using?
• Have you already tried performing the troubleshooting steps suggested by
  Mauro Cavallin on June 16, 2017?
• Are both of the monitors not working just like what the original poster was experiencing? If yes, have you tried disconnecting one of the monitors? What was the outcome?
• What troubleshooting steps have you done so far?

We will be waiting for your response.

Windows 10 KB3213986 Update Cripples Multi-monitor Gaming

The recent Cumulative Update for Windows 10 (KB3213986) cripples multi-monitor gaming, looking at the way Microsoft worded its "known issues" text. After the update is applied, users with multi-monitor setups could experience screen stuttering or clipped screens when running 3D apps on machines with more than one monitor. The only workaround Microsoft suggests for now entails running your 3D apps in non-fullscreen modes, such as windowed-maximized (pseudo-fullscreen) or windowed modes. Microsoft also goes as far as to suggest that people with multi-monitors could try starting their 3D apps with just one monitor connected.

"Users may experience delayed or clipped screens while running 3D rendering apps (such as games) on systems with more than one monitor," the change-log for the KB3213986 update reads. "To work around this issue please consider the following options: 1. Running the application in Windows mode (not full screen), or 2. Starting the application with only one monitor connected," it adds. The update effectively cripples multi-monitor gaming, using technologies such as AMD Eyefinity or NVIDIA 3D Vision Surround.
