Since there are only two major players on the high-performance discrete graphics cards market, we are going to take a look at two approaches to building a three-monitor configuration. They are the “AMD way” and the “Nvidia way”. Some might think that as long as the success if guaranteed, the differences between these two approaches are negligible. However, in fact they aren’t, but before we get to that, let’s discuss the overall advantages and drawbacks of a configuration like that.
The math is quite simple. A human body and its mind in particular have a very complicated sensory system. Take sound, for instance. An average person has no problem determining where exactly the sound is coming from and where the sound source is moving. To create an illusion of real-life sounds, we developed satellite speakers with stereo capabilities and when that wasn't enough, a system of four, five, six and even seven speakers found its way into our living rooms. If you, for some reason, never had the pleasure to experience a speaker system like that, do it and you will be amazed (especially if your favorite gaming title or movie natively supports it).
You are probably saying: “yeah, I get it with the speakers, but why should I care about three monitors?” Our eyes, just like ears, help our brain to interpret what the object looks like, what its properties are and, most importantly, what it is doing. As it turns out, our flat screen TV-sets and even high-end gaming displays distort reality quite significantly. In a way our dependence on technology makes us actually live in a 2D world or 2.5D at best, since we try to emulate 3D images in books, pictures, mobile phone screens and displays all the time. But it isn’t necessarily working as we don't perceive the real-life world around us as a mere flat image.
This is where triple-display configurations step in. Thanks to slight angle and setup positioning, satellite monitors in theory should provide gradual object and scenery change. So, first your peripheral vision is going to spot the changing conditions, and only after that you will focus on the details on your main screen. But I think you’ve had enough of speculations already, so let’s get down to much more exciting technical details behind this matter.
