My home server is a Proxmox machine with some VM one of which is Open Media Vault from which a Windows PC plays videos to my TV. I want to get rid of the Windows PC and connect the TV directly to the server with an HDMI+USB RJ45 extender, but…how do I get a GUI from it? Is it even possible? I would need to connect to a Windows VM because for what I know Netflix only plays 4K videos with Edge. Thanks!
Didn’t you answer your own question? You need a windows vm, so install windows in a vm and connect your TV to it.
You might need to do a gpu passthrough for the hdmi cable to reach the windows vm video out.
Also, fair warning, controlling Netflix in a browser is probably impossible with your TV remote, so you’d need a mouse and keyboard. An android/google-TV box like the nvidia shield is much more user friendly in that regard.
