In my opinion, which is just personal observation from being a consumer not an engineer or some mad scientist, you should not only focus on the the dynamic and static contrast/aspect ratios. Picture quality to the human eye also relies heavily on the refresh rate and refresh rate response time, I personally will never purchase a tv under 240hz or over 5ms response time. And everyones eyes are different, so always go in person to look at models before buying, for instance most people love sony bravias for some reason my eyes think those things are fit for a baseball bat and a dumpster with the way that they are priced, again just my eyes. And even in person it's always a crapshoot, due to large cable runs, image feeds being split improperly a gazillion times, large dep't stores not setting the tv's image to optimum settings, or the resolution of the image feed not being adjusted correctly. Also 1080p or "fullhd" can't be fed with most basic cable boxes, most providers only offer up to 720p, so check with your cable provider if your mainly using the tv...for tv, im not sure about satelite. Gaming relies more heavily on refresh rate also, especially online gaming if your into that stuff. And once you've actually selected the tv for you and want to utilize it's full potential of the image and sound capabilities get a bitchin blu-ray player, a diesel ass hdmi cable, and let 'er rip. And all of the above goes for computer monitors also, the most important thing with monitors- !!!making sure your video card can dish out the hd image you want!!
