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!
You could install something like jellyfin on server side and if your tv has web browser by any chance you could watch stuff like that. Otherwise you can install a normal desktop environment like kde or xfce on server side.
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.
It doesn't have to be the main GPU. I'm not even sure it would be possible to pass through integrated graphics. But if all you need is HDMI output, you can use the absolute cheapest GPU you can find (assuming there's an open PCIe slot). PCIe pass-through does require CPU support (Intel VT-d or AMD-Vi) on the host and may need to be enabled in the BIOS/UEFI. I have an NVIDIA Telsa card passed through to a VM on my Proxmox server, but I'm only using it for compute; my card doesn't even have a video output.
