Hi,
just upgraded fro El Capitan to High Sierra (I have a late 2011 Macbook Pro) - which I connect to my TV via HDMI all I get is the High Sierra mountain screen - nothing else, except the sound from the film I'm playing on VLC. None of the posts on this HDMI/High Sierra question mention just seeing the Mountain screen. Any help most appreciated - because I don't want to reinstall El Capitan if I can avoid it.
