Solved: TV reports HDMI unsupported when powering on OSMC after install

I couldn’t spot this in the forums, but I’ve ran into this before. The initial installation on the TV went well and then the PI rebooted, and after a second it switched to ‘hdmi unsupported’ (with nothing but a blue screen).

I’ve got an older Konka TV and found it was necessary to add this to config.txt


The various hdmi modes are explained here:

I had previously had success with hdmi_mode=4 (720p), but was fairly sure my TV was 1080p, and sure enough ‘16’ worked for me.

Your link was last edited over a year ago. For completeness, I’d suggest this page to keep up with config.txt documentation
