With everybody working from home, you may wish have your multi monitor setup at work on your multi monitor setup at home.
The old way to do this is to set the height and width of your home setup to be the size of both your screens combined. Lets say you have two monitors that are 1920W x 1080H. You would then set your width to 1920*2=3840 and your height to 1080. The problem with this setup happens when you maximize an application, then it maximizes it across both screens.
%windir%\system32\mstsc.exe /w:3840 /h:1080 /v:(your work pc ip/name)
With the new method, you can set the multimon configuration and it will use all your home monitors automatically and keep your applications within each monitor properly.
%windir%\system32\mstsc.exe /multimon /v:(your work pc ip/name)
If you create a windows shortcut for remote desktop and then edit the properties, the above settings are what you would apply to the target value.
