I have a cable box for one tv and I am looking to split that via hdmi to a new Roku tcl tv. I have the splitter set up (cable box to splitter ‘in’ and one for each tv on ‘out’, on the right hdmi source and I’m getting an error on the Roku tv that says “HDMI 1 (Arc) No signal - is it connected”. I can’t figure out what I can be doing wrong and all of the cables are connected securely.
Any advice would be appreciated. Thanks
