Windows 10: Is a Duplicated Display recognized as Dual Monitors?

(Windows 10)

Sorry what may be a stupid question, I've looked high and low on search engines but I can't find something related specifically to this.

Basically, I am going to be using a chrome browser extension that restricts use of dual monitors for security purposes.

Obviously extended displays are going to be flat out restricted, but could I still use the duplicate monitor setup to blow up the display from my work Laptop to a Larger monitor? Would Windows still recognize the set up as a "Dual Monitor" Setup?

Thanks in advance.

How to duplicate 3 displays in Windows 10?

I'm running a setup with 1 monitor and 1 computer with an RX470 where they are connected with 3 cables: DVI Dual Link, HDMI and DP. Both Windows and the AMD software correctly detect these connections - as 3 monitors. I switch between the input type via a button on my monitor. The problem should be the same with 3 different monitors and any connection types.

Windows allows me to:

• Disable any of them.
  
• Extend any of them.
  
• Duplicate any 2 of them.
  

However, I want to duplicate all 3. I read a bit around other sites and it seems to be a limitation of Windows 10, but I didn't find a definitive source. Some suggest that you have to use additional hardware like a splitter.

Duplicate two displays.

Hello Barry,

To assist you better I would like to know, what is the make and model of the computer?

Meanwhile, let’s try simple troubleshooting steps and check if this helps in resolving the issue. Follow the below methods.

Method 1.

I recommend you to uninstall/reinstall the display adapter driver and check. Follow the below steps:

• 
  Press Windows key + X and click on
  Device manager.
  
• 
  Locate for display adapter and click on it to expand.
  
• 
  Right click on the device and click on
  uninstall.
  
• 
  Once you are done uninstalling the driver, restart the computer. It will automatically install the generic display adapter driver.
  

If this doesn’t help to fix the issue. I suggest you to update the display adapter driver. Skip step3 from the above steps and right click on the
device and click on update.

Method 2.

If the above method did not help to fix the issue, I would suggest you to
go to the computer manufacturer website and download the latest display adapter driver. If the display driver is not available for Windows 10, try installing the available driver in compatibility mode and check.

• 
  Right-click on the setup file of the driver and select Properties.
  
• 
  Select Compatibility tab.
  
• 
  Check Run this program in Compatibility mode.
  
• 
  Let the driver install and then check the functionality.
  

Hope it helps. Keep posting us with the status we will be glad to help you.
