The following article provides help with setting up a remote terminal session with dual monitor support and various other Remote Desktop Service tips such as using Control + Alt + Del when in a terminal session.
Dual Monitor Support for Remote Desktop Connections
Remote Desktop Connection supports high-resolution displays that can be spanned across multiple monitors. The monitors must be the same height and aligned side by side. To have the remote computer’s desktop span two monitors, type Mstsc /span at a command prompt.
This feature is sometimes called continuous resolution. To toggle in and out of full-screen spanned mode, press CTRL+ALT+BREAK.
