I bought a fiber optic cable to connect directly to a new Yamaha TSR-7850 receiver and a new Samsung QLED. It works when sending 1080p content from Tivo Bolt Vox but does not send any signal to Chromecast Ultra. The screen keeps turning on and off when trying to use Chromecast Ultra. I don't know why as there are no crazy bends in the cable and they connect directly to each other. All connections on the AV receiver, as well as on the television, are HDCP 2.2 compliant. I worked with tech support but we were unable to resolve the issue. I recently sent the fiber optic cable back.
