I was looking for a fairly simple way to get the best picture out of my VIZIO M470VSE-4.I'm comfortable doing more advanced calibration if there aren't any good options for beginners.I saw that article on the main page today and that's how I got the idea.I don't have a hundreds or thousands of dollars to spend for it though.I do have a few Disney and other Blu-Ray disc's but I don't see that calibration software Ive read about on the back of the case.Is there any free software that's decent ? I just don't know if its worth it to spend the money if may not see any improvement.
