Hello all, I recently bought this video card with the intention of hooking up my two 19", a 21" and a widescreen HDTV together (not eyefinity). I have bought two of these adapters to use with the 19" monitors, and I'm using DVI -> VGA adapters for the two other monitors. When I just have just the 21" and the 19" monitors plugged in it works flawlessly. The problem is plugging in the fourth monitor to the dual DVI port. I only get two monitors to respond then. What might be the problem?
