I need more screen real-estate for productivity work (programming, excel, etc) and am considering a 3 side-by-side setup (3X1920 x 1200). I'd like to find a way to usefully incoporate a touchscreen into this setup.
Is there any software currently available that would allow me to setup a touchcreen that can view part of an extended desktop, possibly allowing me to pan the view of the touchscreen within that view?
Alternatively, how difficult would it be to setup the touchscreen to duplicate a fixed part of the larger extended desktop (like the center monitor) while still extending the desktop across other monitors?
Is anything like either setup supported by NVidia or AMD drivers and would this necessarily require 2 graphics cards? If not, are there any software options available? I may be willing to upgrade graphics hardware if necessary, depending on expense.
I saw gimespace referenced in another question but it doesn't seem to do what I'm looking for.
Edit:
As an alternative, does anyone know if remote desktop from a high resolution tablet like the Nexus 10 could be made to work for this purpose and any software that would support scrolling across all the available screens?
I am using Windows 8 Pro version.
