As DaGamePimp also mentioned, I think you are definitely missing out on a good picture. Dynamic, and in my opinion every other factory preset, are indeed far from accurate. You can have a tremendously better picture quality on your TV, which requires calibrating.
Now, I certainly agree with DaGamePimp's statement that no other form of calibration can be as good and as accurate as the professional one with pro equipment and software, but the only slight issue in this case might be that such pro calibration easily costs $400 or more in some cases, which is hefty for the TV that barely costs more than a grand. Maybe there are cheaper calibrators out there (and I wouldn't count Best Buy), but it's not cheap either way... So if anyone is ready to spend like 30 or 40% of the TV's purchase price to adjust the picture on it, by all means, there is no better way to get the ultimate PQ your TV can provide. I have done it on my other TV, but it was certainly worth it on that one, since it is a lot more expensive set and with the best picture on the market today.
But on the 640U, I am personally opting for the next best thing, which is calibrating myself with calibration patterns, and the mentioned calibrated reference set. Yeah, it's not 100% accurate if measured by a professional light sensor and equipment, but it is good enough to achieve a considerably better PQ than any preset and even to amaze. Sure, the pro equipment could measure some errors and correct them, but I frankly do not think they would be so strongly noticeable to the human eye any more. After all, my eyes watch the TV, and my eyes can barely see that much difference when comparing to the mentioned calibrated reference set. So that's good enough for me personally on the 640U, and it costs me nothing...
Anyway, I'm just saying not to discount the possibility to achieve very decent picture quality (even if not 100% pro perfect) with some of the free tools and doing it yourself, especially if pro calibration turns out expensive.
Whatever you opt for, I certainly recommend to do some calibrating on your set, and at least to start with maybe some of the posted settings here, or on CNET, which may already show you a huge difference in PQ... Good luck
