It's been a few years since I first posted my results with using a secondary 7" monitor to display the VMSpc screen. It will work with any PC that has a VGA port for an additional computer display. Silverleaf has done a good job interfacing it with Windows Vista. I have run it for over 2 years with Vista, and it has worked flawlessly. It saved me a lot of time on a breakdown I had where a fuel rail sensor went bad and I was towed to a Freightliner dealer. I was able to provide the service writer with a printout showing the VMSpc description of the fault code. The dealer still hooked up the Cummins program to diagnose the problem, but VMSpc pointed the way. The addition of an additional monitor has been the perfect addition to my gauge array. The pics can be found in the "Favorites" section of the menu.
