There's a tech team not far from where I live, setting up some dual monitor systems. They are not running 3d applications, rather a lot of text data in streaming/persistent scrolling format. Currently they are using AMD X2 6400s, 4GiG DDr2 RAM and a Matrox GPU found here : http://www.dabs.com/productview.aspx?quicklinx=50R8 Originally the guys had been using an Nvidia GTS 512, and found that it couldn't keep up with the refreshing of the scrolling data across the 'second' screen. They then moved to the Matrox because they are designed for this type of thing; and by looking at their products I would have to agree. However the guys are still facing the same slow response/chugging on the second monitor. They've switched physical monitors and nothing changed. I've looked at the drivers, the rest of the components, the background services etc. Nothing seems to be wrong. The CPU and RAM usage is fine during all of this. I'm not really big on multiple monitor solutions. What are some common/known variables that could cause such a response on the second screen?
