I realize it is not the preferred way to go, but will a touchscreen work on the old chassis Hedgehog4 if plugged into the internal VGA port to configure/set resolution and then any of the USB ports after re-starting per the instructions in the manual? When I purchased the full-warranty old chassis unit less than a year ago, your authorized service center told me I could upgrade to the next level, but I now understand you have to go (you'll pardon the expression) "whole hog" and we simply don't have the money available to do that, nor do we need any additional features. I was able to connect a regular VGA monitor and see the startup screens and move the mouse between screens, but I was not able to move the Group or fixture screens into the VGA monitor. Appreciate your help. Thanks.
