Ok, not sure what happened here. Tried to post and it would not go through, so if this is duplicate I apologize. New display is not pixelating while displaying Dish, I have no idea why but there it is. I said the PQ was not outstanding, but on par with what we had through Cox is acceptable. It is getting better as I tweak the factory settings. Not sure why the old display pixelates only on Dish, and this one doesn't. Guess that will be the TV service guy's job to figure it out. In the mean time I will just use this new set in the living room. Apparently the old set is not wanting to play nice with resolutions other than 1080p. Worked fine with Cox, but it was also fine with the first Hopper. Something may have happened during installation or something. Whatever the case, I am covered at the moment and my warranty covers a replacement display if need be.
EDIT: Ok, after reading the last post I want to say I did not mean to come off as short. Had a great dane trying to climb on my lap. Anyway, I've been messing around with the picture settings and they picture does show improvement over the other set. I am going to hook the 55in to the joey and see if it displays the same issues, if it does then there is even more evidence pointing toward something wrong with the TV.
