Hi all, After tinkering with lots of settings for a long time, I finally got external HDMI sources to work with the setup of HDMI to AV to Fushicai UTV007VideoGrabber working after changing Hyperion grabber settings from PAL to NTSC (despite living in UK). However, the videograbber only works with the PS4. I hoped it would work with the ChromeCast, but no luck. It screenshots black pictures with chromecast and no LEDs lighting up. Anyone any clue about this? Thank you!
