I understand the basics (HD is clever tv combined with clever sources = better picture) and I have seen a demo (which is mind-blowing/mouth-watering) but I am so confused with standards and formats and resolution. The reason for my question is, not how can I get it, but on my current setup how near can I get to it. I have a Samsung plasma (852 x 480 ish - forgive my inaccuracies) which I know is SD (not that I fully understand SD either) I have a component, a vga, a DVI and two scart inputs. My component input states '480i, p/576i, p/720p/1080i'. If anyone has the patience I coud really use a short explanation of what's what. I've read mountains of stuff but am still confused. I'm trying to improve my PQ without an actual HD setup (my panel is new and I had no choice than to get it - long story). In relation to the 'i' and 'p' formats, which add-on boxes improve PQ to which level. If it's a dumb question caused by my mis-understanding, then I appologise in advance.
