Have a hopper 3 and am thinking about getting a 4K TV. How much 4k content is available on dish right now? Have looked at the dish web site and couldn't find a good answer. Also, most 4k tvs upscale all lower input to 4k. If you have a 4k tv, how does standard HD look on your 4K box. Is it as good as the HD set that the 4K tv replaced? Have read various reports on TV threads but there is little discussion about dish image quality.
