A few months ago, we moved into the brand new house we built. At that time, I had DirecTV installed, servicing a total of eight TVs. I told them I wanted their best, most advanced equipment, regardless of cost. They gave me a Genie 2 and eight wireless genie minis. A short time later, I discovered none of the equipment was 4K compatible, despite the fact that all of my TVs are. So I called and asked about that - why they never mentioned that fact, despite me requesting their "best, most advanced equipment". I wasn't given a good answer, and worse, was told I could not upgrade any of my equipment with 4K-compatible equipment (i.e. C61K) until, like a year. So at the time I just dropped it. Now that football season is upon us, I'm revisiting this because I'd like the best-possible 4K picture for football, at least on one TV - the big one in my primary viewing location. My questions are: Can I just purchase a C61K online to replace one of my genie minis to get 4K content? If yes to #1 above, is it worth it? Will I be able to see a noticeable difference in picture quality when viewing a live event like an NFL game on the C61K vs my existing mini? DirecTV's compression techniques make me question this. Thanks in advance!
