Hi all. Newbie in the UK. I have a KINIVO HS140 HDMI splitter, driving the main LG living room TV, and feeding a Goodmans TV upstairs. It has it's own DC power. After recently switching my TV supplier from a Virgin Media Tivo to a Sky Q box, the upstairs TV will now only get a signal when the main TV is also on. Yet the main TV will get a picture without the upstairs TV being on. Yet when I was with Virgin, the upstairs TV would get a signal without the main TV being on. I did have to switch the Sky Q box to 1080i for the Goodmans to get a signal (it is hard set to 1080i). The LG is also set to 1080i Scoured settings in all kit, and Google. At a loss. Any of you good folks any ideas? Many thanks. Andy.
