I've been the happy owner of a CV1 for a few months now.
I'm currently experiencing the "hdmi not detected" issue and now I'm stuck in the setup loop because I can't continue in the headset.
I first had this problem with the hdmi not being detected a few days and managed to get it working by lots of reboots and unplugging and plugging all the connections randomly, playing the numbers game. I even managed to exit the setup loop by killing the server process in the task manager but that method doesn't seem to be working this time.
(btw, I think the setup sequence should be more robust and allow the user to exit the loop at any stage if they want to.)
