Should I use dynamic contrast on my HDtv?

Unless you are a casual TV viewer, I would not. Certainly if picture quality matters to you, and you want to see as close as you can to what the director intended, you don't want dynamic contrast. That's more of a gimmick to make lower grade panels turn in better results in artificial testing - kind of like installing a NOS system right before you dyno your car, so that it turns in huge horsepower numbers despite not being able to sustain them longer than a few seconds (until the bottle runs out). It's a cheat for the spec sheet more than a desirable feature for actual movie/TV viewing.

Ok my hdtv can do both 720p and 1080p though

So can every TV made after 2009. That's irrelevant. Contrast is the difference between the brightest pixel the TV can create and the darkest pixel it can create, but that difference isn't nearly as big as we would want it to be with most panels. Adding the dynamic contrast feature was a way for the TV to "game the system" to get a much higher "test score" for the specs sheet, but it doesn't improve real-world performance and actually degrades the picture in most cases.

No, never use dynamic anything for video quality, it messes with the colors.
