Infinity Display: In a two-monitor setup, how can I map the right side of each monitor to the left side of the other monitor and same for up and down?
Solution 1:
Multiple Monitors program does what you want, although it's not free. It has a free trial to check it out.
I tested it with 2 monitors. Going right from right one does send you to the left one like in PacMan, but going up or down only sends you in the same monitor, not the other one (which would me a bit disorienting in my opinion).
