Our theater group has an Element (older, two DVI and one VGA port), which I have recently updated to the most recent software. We have one VGA monitor for the console. Am looking for a touch screen. There is one Viewsonic model listed as compatible (no longer available), and I was wondering if anyone has used the currently available model (VA2246m-LED). Does it work? It has the advantage of being inexpensive. Thanks. Also any suggestions would be welcome.
