Hi,\n\nI just bought a new 4k HDR 27" monitor to watch movies in the near field configuration. And once I replaced my old Hitachi TV with this new monitor I got 'No signal'. Exactly the same cable into hdmi input on Toshiba results in FireStick 4k output. What is the difference?\n\nMy configuration FieStick 4k -> (AV3 input) Yamaha a1070 (Output 1) -> (hdmi input) Monitor (or TV)\n\nTo make things more complicated. I also use this configuration - Oppo 103d (Output 2) -> (AV1 input) Yamaha a1070 (Output 1) -> (hdmi input) Monitor (or TV). In this case I have video signal on both monitor and TV.\n\nAll connections are done via hdmi cables. Tried to connect this new monitor - Acer H277HK to my PC and it also works fine.\n\nAny ideas?
