I asked a related question on Stack Exchange and it seems that nobody understands anything there, so I will format this question for here and maybe have better luck.

I am trying to setup 2 NVIDIA GT 610 graphics cards both with 2 DVI, 1 Micro HDMI and 1 VGA output, and 4 27" monitors. I only want to use the 2 DVI outputs on each card to span all the monitors which I already have working. I have two monitors on one card and the other two monitors on the second card. My issue is that I want each monitor to act as it's own monitor (not Xinerama style) where if I maximize and application it does not span across the two monitors that belong to a single card, or I also do not want my dock to span two monitors as well. I know this is a Xinerama feature which works now (undesired), but I would like it to work such as it would without Xinerama on a two monitor, single graphics card setup (maximize to one monitor & dock spans only one monitor & drag across monitors). Here is my current configuration.

I've spent a lot of time reading about it but I cannot find anything that helps me with this particular configuration.

Thanks in advance!
