Has anyone used this process outlined below?  Is it slow based on my half fast network?  Is it an even match, monitor for monitor, on both sides of connection?

launch RDP from the command line and specify the multimon flag:

mstsc.exe -multimon

Launching RDP in this manner will auto-check the "Use all my monitors for the remote session" box and allow you to bypass the previous steps.

Support for multiple monitors is available when connecting from any Windows 7/8.1 computer, however, there are restrictions when connecting to a computer using multi-monitor mode. When connecting to Windows 7 computers, only computers that are running Windows 7 Enterprise or Ultimate can be connected to in multi-monitor mode. When connecting to Windows 8.1, only computers that are running Windows 8.1 Professional or Enterprise can be connected to in multi-monitor mode. Both Standard and Datacenter editions of Windows Server 2008 R2 and Windows Server 2012 R2 support multi-monitor mode.

Multi-monitor mode supports up to 16 monitors, with a maximum resolution of 4096 x 2048 per monitor.

I have many clients who use Windows 7 and even XP machines to connect to 2008 R2 Remote Desktop Servers with multiple monitors. The process outlined above is correct, running mstsc.exe /multimon will auto-enable the Use all my monitors for the remote session setting in the Remote Desktop Connection client.

Is it slow based on my half fast network?
Sorry, not too sure what you mean by this.

Is it an even match, monitor for monitor, on both sides of connection?
Resolution wise? Yes.

Thanks for the great answer.  The "Is it slow based on my half fast network?" was side humor based on the 3000 Comcast commercials forced upon us all everyday!

The "Is it an even match, monitor for monitor, on both sides of connection?" is my concern.  If I have a desktop with only two monitors configured.  Then Remote into with a system with four, can I then using windows, drag these programs around to use all four of the monitors on the Remote connection side?

Sorry, I'm based  in Australia so forgive me for not recognizing the side humor :)

Ah so that's what you meant. In that case no, it doesn't work this way. If you only have two monitors and you connect to a machine with three or four then everything gets squashed into the two monitors for your viewing.

e.g. My work machine has three monitors. When I log into my work machine from my laptop at home, everything gets combined into a single screen. When I log back into my machine in the office the windows generally go back to the monitor they were on originally prior to me connecting remotely from my single display laptop.

Hope that clears things up for you.
