I get it. You think expensive TVs have a better picture and that's why you got one. I'm not saying YOU shouldn't have dome that. I grew up watching black and white TV with pictures that often had snow or "ghosts" so color and cable were big improvements from that. But given the same screen size and reception, it makes no difference to ME at all and even if I am missing a thing or two that's small and blurry I'd rather do that than drop four figures on a TV that might, and might not, let me see those things. When I have watched pricey TV I just haven't come away thinking that it looked so much better than mine and I should get one.
Good, you agree that a new TV is better. I totally understand if it's not worth it to you. But don't say new TVs aren't better just different. They are measurably better in many scientifically tested parameters.
