I have a fancy OLED TV, not connected to the internet. A powerful desktop running MS Windows 10. And a fancy sound system with Dolby Atmos. First MS Windows is the only way to get Netflix and similar to stream the 4k HDR Dolby Atmos stuff outside of smart TV applications. It will silently stream the lower quality without telling you. So if you do not tinker, you must use the smart TV crap to get any chance of watching content at the capability of your hardware. Then comes the bugs. Randomly the TV and Sound system decide they cannot transfer sound anymore. It's just as if it is on mute. To be clear the connection is pc -> tv-> sound system. Using 48gps HDMI cables. The only solution is to unplug both the TV and the sound system. Reboot is not enough. Unplug one is not enough. It has to be both. Btw if you do not have the right HDMI cable you will also get lower resolution and refresh rate. Without any recourse. No information reported anywhere until you learn that pressing 7 times the green button on the LG TV remote finally gives you the details on the active HDMI connection. Oh and by default the sound setting of the TV will also decide atmos and convert it to 5.1 PCM before forwarding to the sound system, while you really want a passthrough to the sound system. Basically nothing really works. So if you do not tinker I am not sure you even get the advertised quality and features. With that said ignorance is bliss.
