Evaluation - Clients with dual monitors?

I am currently evaluating RDM and plan on using it as a way to RDP to my servers as well as connect to my user's workstations for support. Right now I am using LogMeIn to connect to them but since they are increasing their charges and we are not really happy anyway I am going to be moving on. I have been looking at a bunch of the products that RDM supports such as Teamviewer, Dameware, etc. What are you using to connect to your workstations with dual monitors? Is there anything that is embedded in RDM that works well with dual monitors? I saw that Teamviewer isnt integrated and that is the one I almost purchased before I found RDM. If it isnt embedded but still allow you to list all of the workstations and connect to them in the native client quickly I would be interested in that as well. Thank you for your opinions.
