Can't get multiple monitors to work with windows remote desktop

My remote desktop session is refusing to use both monitors. Here's how they are laid out

I do have the option checked in the Remote Desktop Connection

What else can I do?

Multiple monitor support in RDP is only supported for Windows 7 Ultimate and Enterprise according to Remote Desktop Connection: frequently asked questions . Only the connecting client needs to have Ultimate or Enterprise, the remote host can have Windows 7 Professional.

Have you tried passing /span to mstsc as mstsc /span? It's a bit clunkier than full multi monitor support as it all appears as one monitor on the windows 7 system but might work for your purposes along with something like splitview...

I think there is a solution.... RDP Wrap https://github.com/binarymaster/rdpwrap/releases https://github.com/stascorp/rdpwrap/releases

(Search google for rdp wrap or rdp wrapper to get more info about what it does/how it works)

Basically, this software can be used with Home versions of Windows(7) to allow remote desktop sessions, and multiple sessions. I had installed it in that manner, and just noticed that if I connect to machine (running Windows 7 Home Premium) with this wrapper and tick the checkbox on the remote client to use all available monitors for the RDP session - IT WORKS!! I have 3 monitors and they are all active in the session and this is in true multi-mode not the stupid split-screen. So, I think it would work in similar fashion on Win 7 Pro.
