Received my Firefly 8SE from Hajimoto (TU). I haven't been able to use the HDMI output to view on an external monitor for setup like I have seen others do. I keep getting "cable not connected" warning on the monitor. I've tried (2) different new HDMI-to-Micro HDMI adapter cables on (2) different known good monitors. The firmware version on my Firefly 8SE is "UN124". That's different than anything I've seen online. I tried to go back to "U115" that's the most recent on Firefly's site, but it did not revert back to it. Still on "UN124". Anyone seen this before. Maybe this is why HDMI output won't work?
