Where the Canvas touch input doesn't reach

I have my Dell Canvas 27 set up as the main input device with an extended monitor stretching to 2nd screen. The touchscreen however doesn't go there... I am currently using a mouse to work on the secondary screen. Every time I touch the touchscreen however, the cursor jumps back onto the primary screen. Mightily anoying.

Is there any way to work in my art programs using touch on the Canvas screen and have a mouse exclusively working in the other? A bit like having 2 PCs.
