My parents are getting a new tv, and are asking for recommendation. I think all I can influence is the brand/model (not realistic to propose rpi and more complex systems). I instinctively avoid google/android and lean towards anything else open source, so probably LG WebOS… But I had bad luck searching for more detailed comparisons. Maybe you have experience or opinions?
Look, my answer was simply that web-OS supports Jellyfin and local streaming. Whether you think it’s hard to set up or not is your opinion. I don’t think Grandma is a typical use case scenario for this.
