I currently have a 40-in Sharp LCD Aquos (5 years old) and I want to upgrade to a 50-in or 60-in LED or Plasma TV. My 40-in Sharp has a very clear picture when using the HDMI inputs. I am looking at Samsung, Panasonic, LG, and Sony models. Won't the picture (that I am used to on my 40-in screen) be "washed out" if I go to a larger screen? I plan to go to BestBuy to look at the picture quality on the 40-, 50-, and 60-in TVs. but maybe someone can advise me until I do.
