Windows 10: Only one of my displays does not duplicate

Hiii !I have a dual PC setup. I run 3 monitors Acer 1, AOC 2, AOC 3, and an AverMedia Capture Card 4 on my gaming PC. The streaming PC hosts the AverMedia Capture card.On the gaming PC's display settings, I am unable to duplicate my "main display" which is 1 onto the AverMedia Capture card which is 4. The screen updates and shows 14 are duplicated but the changes are not visually shown, and then the setting reverts on its own after about 2 seconds.I have tried matching the resolutions and framerates. I rolled back Nvidia Drivers. I updated the GPU again, and did all windows updates.

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.

 

Duplicating Display

I didn't realize that but I will sure will look and give it a try. But first, I need to figure out how to get into the BIOS... - - - Updated - - - Thanks for reminding me to look into this but no such setting in the BIOS. However, what I did notice is the machine creates a 3rd display when I pick "Duplicate". As you can by the first screenshot, it appears as just "wired display" and the second screenshot shows 1 & 3 being recognized and not 2. Then when I go back to extend I have 3 displays instead of 2. So keep this in mind, the additional display is listed as 3 in "display settings" where it says to rearrange your displays but 2 in "advanced display settings." Lastly, in advanced display settings, the LCD monitor not shows a status of, "isn't active". I'm puzzled, any ideas?
