This is definitely going on my wish list for FSX. 3840x1200 gaming...
In order to power the maximum resolution of 3840x1024, a dual-link DVI connection is needed. While many PCs today have dual-link either through their motherboard's video out (notebooks) or their graphics card (desktops), there are many that don't and it's because of this that Matrox included the analog VGA connector on this product. This allows Matrox to market the TH2Go Digital to many more people than they would be able to without the VGA out port.
