I'm looking for something like MaxiVista that lets you extend your monitor to a second computer monitor. However Maxivista is only Windows base. My main computer is Windows 7 and the other computer I'm trying to connect to is a Mac. Note I am not trying to share my keyboard or mouse, I want to use the Mac as a third display.
I try several things and I found a working solution using MaxiVista :
On the Mac computer :
On the PC computer :
I know this isn't really full screen, but it's the best I can do. (You'll only see the top bar and arrows on the right/down)
Maybe, you can try to better simulate full screen mode with plugins like MegaZoomer, but I don't know if this works.
