I just received a new Librem Mini yesterday and I had planned to use it (at least temporarily) headless. To set it up, I had planned to connect it to my TV via HDMI. When I booted it, I could see the bootloader screen and the boot selection options, but beyond that, the TV reported no signal. I’m curious if there’s something I need to do on first boot (boot from USB to install PureOS?) or if there is something about a TV’s settings that might need to be changed to get this to work. Unfortunately, I don’t have another compatible monitor I can try.
