@gemlog As for the resolution — you're right of course, it doesn't matter that much. I'm perfectly fine with 720p if the video is encoded properly. It's just that this huge ass TV is relatively new and I still can't get used to it and somehow attempt to justify it being 4k.
Not that I really need it, I have two 30" Apple Cinema displays — they are old, but are still considered very good.
So… 4K is not a requirement for me, I do it rather out of curiosity when the opportunity arises 🤷
