I too was unable to get Sdesk to work with Aurora, and I am quite computer literate. I ended up making my 1400x900 laptop display more by going into my video card's setup software and finding a box which says something along the lines of "show all available display formats, even if this computer doesn't support them" and checking it (I had to look quite a while to find it, and wasn't in an obvious place. I may have needed to go in as administrator on my laptop.). Now my computer displays all kinds of display sizes, which scroll off the edge of the screen.
