I had exactly what you have, and kept Charter for phone and internet while switching the tv to Dish Network. Ended up saving quite a bit wqith their introductory offer, and the tv is much better. With cable, when they'd pan across a football field, I'd get diagonal lines across all the yardlines. Or during a race, if the camera followed a car or 2 along the straightaway, I'd get diagonal lines in places on the screen. It was awful. With Dish, I don't get those lines, and they have a ton more HD stuff, as well as some hd in true 1080p. The picture I get with Dish looks like the picture the tv got in the store. It's phenomenal. The only downfall is that Dish doesn't carry the MLB Network yet. I probably sound like a commercial for Dish, but I have no affiliation with them whatsoever, other than being an extremely satisfied customer. I had DirecTV in the past also, but not with a good tv set. It may or may not be as good.
