I've connected my XBox to the component inputs on my Toshiba 57HX with Monster 400X cables. Colors are brighter, but the edges appear much more jagged. Also, there is more graininess than when I connect to the Video inputs. Is this just because I'm watching it on such a large screen? Naturally I would expect some imperfections, but in many ways it looks better with the standard video connection. That doesn't seem right. Any thoughts?
