Hi guys, I have a concern about upgrading to a 4k tv, that I'm not quite sure the answer to. I remember when DVDs came out and we all had 480 tvs, everything looked fantastic. Then HDTVs came out and now 1080 was amazing looking on them. But viewing that old 480 matierial on a 1080 tv looked like absolute crap. From my point of view viewing 480 material on a 1080 tv looked waaaaay worse that watching that same material on a 480 tv. Be it the increased resoulution bringing out all the imperfections, or just bad uprezzing algorithms I don't know, but taking source material that was native 480, viewing on an HDTV was actually a step backwards. I'm concerned now that the same thing will happen going from 1080 material to 4K. I replaced my DVD collection with 100% blu-rays when the move to HD happened, but there's no way I can do it again for the move to 4K. I know my next TV purchase will probably have to be a 4K tv, and I'm wondering if my now vast library of Blu Rays will no longer look as good on that new TV as they do on my current one. Is this an unfounded fear? Does it depend completely on the TV itself and what uprezzing algorithm it uses? I'm sorry this is such a general question with probably a ton of specific variables in the answer, but I'm just looking to get a sense of what to expect when upgrading, and what people's experiences have been.
