Suppress HDMI input pop-ups on Extron IN1608 xi

[adampeterson@gmail.com]

I'm currently doing my first broadcast with our new Extron switcher. It's going well, but every time I switch to a different input, a popup comes up on the screen telling me the resolution and the currently active HDMI port. I don't think people at home need to see this. Is there any was to prevent this from popping up?
