Why do I get this weird full screen resolution?

Where does Parallels get this weird full screen resolution on Mac's retina display 3360 x 2100? Windows tells me that this is a "Recommended" resolution and keeps changing to it every time my Mac wakes up from a sleep. How can I specify actual resolution 2880 x 1800 and make it permanent?
 
Could someone please help? This part of Parallels was stable for many months and now whatever settings I change, Windows OS keeps switching to 3360 x 2100 at every occasion.
 
BTW, from the screenshot on this article I see that it is about Windows 7 and I am running Windows 10 as you can probably guess from my screenshot attached above.
 
Pretty bad support from Parallels. I found an answer on VMWare Fusion forum. It appears that 3360 x 2100 is a virtual resolution that macOS uses on its displays. Then the OS hardware layer scales this down to 2880 x 1800, which should in theory improve viewing experience. It is called "scaled resolution". So now I am not sure if Parallels and other applications have access to hardware layer in macOS, because Fusion also seems to jump to 3360 x 2100 as default. So maybe 3360 x 2100 should be default.
