I have a new MacBook Air with (2) Samsung monitors. I would like to keep my MacBook Air closed. Currently, I have everything working except the Samsung monitors mirror the display of the MacBook Air monitor. I would like one monitor to mirror the laptop and the other to be extended so I can drag screens over to it. Help and thank you!
MacBook Air 13″, macOS 10.15
As I suspected based on the info you provided, the dock is the problem. This is from the product info on Amazon:
As you can see, it shows the Mac 'extend mode = non-mirror mode' – I've never heard that term before, but the image makes it clear that you're not going to get separate desktops on the external displays.
I'd suggest a dock from Elgato, OWC, Belkin, Kensington or Brydge (Stone Pro) as those will provide true dual display support. There's a reason those docks cost 4-5x the one you bought.

Ok, let's dig deeper.
Ohhhhh noooooo! Below is the listed spec from, yes, Amazon. I am keeping my fingers crossed. LOL

I am connecting the displays using a USB-C docking station.
When I pulled up the About this Mac section, I was able to get the Mac to have a different display from the two monitors. However, the two monitor's when the laptop is closed still mirror each other. I really appreciate your time in helping me with my issue.
Your Mac can drive two displays up to 4K as extended desktops (in addition to the internal display), so it should work. Next question is what docking station? Not all of them support dual displays (particularly some of the 'off brand' ones that are available on Amazon, for example).
With the Mac closed, go to system preferences > displays > arrangement tab and untick the mirror displays box.
Thank you for replying. When I close the Mac, the arrangement tab disappears. The only time I see the arrangement tab is when the Mac is open. At that point, the 2 monitors are mirroring the Mac.
You are brilliant! Thank you for all your time!!!!!!!! :)
You're welcome!
