im hoping to get a little guidance. I picked up a new TV that supports 4K and HDR. It's a Sony XBR. I've got an ATV 4, Mac Mini(2015?) base model, or a 2015 MacBook that I can use, or a Panasonic BD Player but I don't think that will help. I'm wondering if I have options to download 4K HDR content and watch it. I have a 10MB Internet connection so I do t think streaming will work. Or am I wrong? I'm hoping I can maybe download some HDR content just to kind of check out the TV and see how good it could look. What's my options?
