Hello, this would be my first TV and I'm a bit hesitant which way I should go. I don't have the money for OLED, so I looked the next two TVs: Sony KD49XD7005 and LG 49LH630V. I would watch it from around 1.8-2 meters. Would I be able to constate significant difference in picture quality with full hd content? It is also important, that I don't want to change at least for 5 years. Mostly HBO + football and few full hd movies would be the content.
