I've got a 550exn with a pretty standard configuration that also utilizes the VGA connection to display content from a local laptop. Inputs are controlled via an Extron controller on the wall, and I'm running into an issue where we'll change the input to VGA, and then after a few minutes, the input will automatically change back to MagicInfo. This happens even while content is being sent from the laptop to the display.
Any thoughts on what might be causing the input to automatically switch from VGA back to MagicInfo?
