I bought a Jetpack expander off eBay and the hdmi port did not work. I couldn't find another in my area to test to see if it was a camera issue or the Jetpack expander, but a rental house allowed me to use their base expander and the sdi and hdmi port both worked with that. So I'm a bit confused. I just received a message from someone stating that their hdmi port on their Jetpack expander also doesn't work. So my question is if anyone has a scarlet-w and a Jetpack expander, are you having any issues getting an hdmi signal?
