Windows 10: HDMI to VGA Adapter in windows 10 is working, but can't duplicate and extend.

What is happening right here?

I have a dual monitor setup(one old monitor, and another new laptop).



I can't extend the displays, and neither I can duplicate the displays. All I can do, is to watch in either of the screen.



i.e either in my new laptop's screen or in my old monitor's screen.(That confirms that the adapter is working??)



What is happening here, can anyone tell me?

Can't duplicate display on HDMI and VGA outputs (ATI Radeon HD4200)

I'm running Windows 10 Pro x64 on my HTPC based on a Asus M4A785D-M PRO board (with an onboard ATI Radeon HD4200). I have the HDMI output connected to my TV. I want to pass a 2nd (duplicate) video feed to another (analog) display using the VGA port. None of the options in the Windows "Project" settings seem to work as I want however. If I select "Duplicate", which seems to be what I want in theory, the HDMI output goes blank while the VGA output displays the desktop. If I select "Extend" I can see the main desktop on the HDMI output, but the VGA output shows a different display (i.e. an extended desktop).Is there any way of getting the same desktop to be displayed via both the HDMI and VGA outputs?

 

Lumia Display Dock and HDMI to VGA adapter

just to understand some constraints:

• HDMI is electrically compatible with DVI
• DP outputs from most PCs have an HDMI compatibility mode that allows for:
  • DP-to-HDMI passive adapters [passive means it just uses wiring (no ICs) between the connectors]
  • DP-to-DVI passive adapters
• In contrast, the USB Type-C output on the Lumia 950XL/950 phone and the DP output on the Display Dock do not have HDMI compatibility mode. To drive HDMI, DVI (or VGA), they require active adapters incorporating bridge ICs. The tipoff is usually that such
  an adapter costs $20-$40 instead of ~$10 for a passive adapter. There’s no good way to tell active versus passive other than by part # and spec.

 

Unable to display to a VGA projector in Windows 10

Hello,

I have an Acer One S1002 laptop/tablet. I use the Micro HDMI output with a Micro HDMI to VGA adapter. This worked properly when I originally purchased the laptop, but, after upgrade to Windows 10, I have not been able to project to a VGA projector. The
laptop recognized that the second display is there, but it does not extend or duplicate the screen.

This works fairly well with my Micro HDMI to HDMI adapter (although, occasionally, the signal will disappear for about 2 seconds before returning.

I have also upgraded the Intel graphics drivers for the computer, but no change.

Can you help?

Thank you.
