When you are editing preferences for your Mac Remote Desktop Connection, there are limited display resolutions you can choose for the remote desktop size.  You can also choose “Fit to Window” but this scales the window instead of changing the screen resolution which sux.

However, there is a way to define your own preferred resolution (assuming the windows box you are connecting to can support it). Use TextEdit to change the saved rdp file for the connection you want to change. See below for an example where I set the resolution to 3820x1150 (this works good with my Dual Head2Go on my MacBook).

On another note, Visual Studio development via VMWare or Parallels is just not fast enough for me on my MacBook Pro. Even though it probably does not significantly reduce productivity, it is frustrating to have to wait for windows to pop-up and builds to complete. I’m just not used to having to wait for anything in my dev environment. I’m thinking this is due to running on a laptop not due to running in a VM on Mac since running a VM on my Win server is actually acceptable. The good news, I suppose, is that this means there is no reason for me to get a high-performance MacBook/MBP when I give this one to my wife the end of this year. Maybe even a MacBook Air will do...
