Windows 10: Possible to duplicate extended desktop?

Hi, i have a laptop connected to 2 monitors, total 3 displays. Laptop is display 1, followed by monitor 1 is display 2, monitor is display 3.Is it possible to extend my laptop to display 2 and also to have duplicate of this extended desktop shown on display 3?i.e. display 1 is main laptop desktop. Display 2 and 3 are both showing the same duplicate extended desktop.

Can I extend my desktop and duplicate the extended desktop on 2 screen

Howdy,

I have a Dell E6430 Laptop with an Intel HD4000 and an Nvidia NVS 5200M card in it. I can use this laptop in a docking station and run on 2 monitors + the laptop screen for a total of 3 displays.

What I want to do is have the main desktop on the laptop screen and then extend the desktop to the other two screens so they are identical. Basically duplicating the extended desktop. I need to show a presentation on two screens at once that are facing opposite directions.

I've gone into Display Properties and tried all the various extend/duplicate type options I could find but wasn't able to accomplish my goal. Does anyone know if this is possible or if Windows doesn't support this? I was able to get the laptop to duplicate to one screen ans extend to the other but couldn't find a way to extend and then duplicate that.

Hopefully that makes sense.

UPDATE: Forgot to add that I already have a VGA splitter that I can use that accomplishes the same thing but one of my displays is 100' away and when I connect that cable it makes the other display (a projector) get all wonky and show wavy lines moving through the image which isn't acceptable. SO just trying to do it right from within Windows and the Dock.


Thanks!

Yes. I know what Extend and Duplicate are. I want to EXTEND the desktop onto one monitor and then DUPLICATE that monitor onto another monitor. 3 displays in all. two are the same, one is not.

Hi Alberto,

Based on the description that you provided, there are settings that we need to configure to resolve this concern. However, we need to do some troubleshooting steps to isolate the cause of this issue. Before we proceed, may we know the following:

• Have you tried extending your display via Windows Settings?
• Can you send us a screenshot of the error message that you are getting? Note: Please do not include any personal information.
