No display from Nova s70 HDMI in

So gone thru steps"First, make sure the TV supports EARC or ARC functionality and has at least two HDIN ports on your TV Next, follow the steps below to connect your device: 1, Connect the game console to the HDIN port of Nova S70 via HDMI cable 2、Connect the TV HDMI1 (supporting EARC or ARC) to the EARC port of Nova S70 3、Connect your computer's signal output to the HDIN2 port on your TV via HDMI cable. When you want to watch the content on the game console: Switch the signal source of the TV to HDIN1, at this time, Nova S70 will automatically recognize and switch to HDIN mode (if it doesn't switch automatically, you can do it manually ). And when you want to watch content on your computer: Switch the TV's signal source to HDIN2. At this point, the Nova S70 will automatically recognize and switch to EARC input mode (if it doesn't switch automatically, you can do it manually" .If I connect satellite receiver or PC to soundbar HDMI IN ,I can get audio(Dolby surround displayed) I just cannot get display. I believe it is more my new Hisense TV not " handshaking" with HDIN as I tried my old soundbar and that doesn't display neither.All is fine if I use TV HDMI inputs but means losing extra HDMI in from soundbar. Have "HDMI Enhanced" set on tv settings and have tried Auto, Passthrough,PCM,,Dolby Digital and Dolby Digital + in audio output but no luck(left in Auto normally).Both soundbar and TV Earc and even when I disable Earc and drop to ARC,still no display. Should there be something enabled/disabled to get display working?.Tried TV/soundbar reset, different HDMI 2.1 cables even cleaning HDMI ports with isopropyl alcohol.When I power on HDIN device I get constantly " HDMI signal received" then "HDMI signal lost'
