Hmmm i was given a link to some software that should allow the taskbar to be spread across the 2 monitors.... but i don't know if that will work with 2 car setups....
If you had a nvidia card that has dual output, then you can easily setup the different background's on each monitor using the NView desktop manager.
Also i noticed in the latest 41.03 drivers (quadro drivers) there is also an option of extending the task bar on both monitors..... i havent had any luck with this yet, but i am thinking its cuz i run the 2 monitors at a different resolution so the taskbar on the 2nd monitor is actually off the screen... if ya understand what i'm trying to say.....
