Dynamic. Good Luck on your certification.
1500:1 is the better contrast ratio
Ultra dynamic contrast ratio is the difference between the darkest and brightest image a TV can have. Ultra dynamic contrast ratio is used in LCD technology and it provides a wide range of brightness and color.
This item has 1440x900 resolution and 800:1 Contrast Ratio.
It is referring to contrast ratio. Contrast ratio is the range from blackest black to whitest white. that said "dynamic contrast" is B.S. (a huge manipulation of the numbers). Look for "Native contrast"
Static and Dynamic Contrast Ratios Faced with several different models of televisions from various manufacturers, the contrast ratio is one of the most important factors to consider in making your decision. A contrast ratio is defined as the difference between the lightest color and the darkest color the television is capable of producing. Basically, higher contrast ratios should yield more vibrant whites and deeper blacks. However, there are several important factors to consider when comparing contrast ratios: whether the contrast ratio is static or dynamic, and what effect your room will have on the visible contrast ratio. A static contrast ratio is the contrast ratio at a given point in time. Imagine pausing a movie and establishing the contrast ratio at that particular frame. Plasma televisions usually have vastly superior static contrast ratios to LCD flat panels. A dynamic contrast ratio is the overall contrast ratio the television can produce over time. Most LCD manufacturers now advertise dynamic rather than static contrast ratios, which often surpass Plasma TV's static ratios. Static and dynamic comparisons each have their pros and cons. A high dynamic contrast ratio is preferable for prolonged scenes that take place in dark settings or black and white movies in general. A static contrast ratio offers superior performance when there are sudden transitions from a well lit atmosphere to a darker one, and vise versa. ---- Recommended Contrast Ratios For Plasma Televisions» Static Contrast Ratio of 5,000 : 1 or a higherFor LCD Televisions» Static Contrast Ratio of 1,000 : 1 or higher» Dynamic Contrast Ratio of 10,000 : 1 or higher---- However, contrast ratio should never be your sole decision making factor. Firstly, most manufacturer's have slightly different ways of measuring contrast ratios. Secondly, contrast ratios are always measured in ideal viewing conditions (essentially, a pitch black room.) Depending on the lighting conditions in your room, your visible contrast ratio will generally be much lower than the manufacturer's claims. In short, a contrast ratio is a useful although imperfect benchmark for comparing different televisions, but it should never be used as a sole consideration.
Contrast ratio is the ability of a TV to change contrast on the set. At this point in time (and referring to HDTV's) at least 40:1 or better is probably preferred. I'm sure that'll improve as technology improves.
Contrast ratio refers to the intensity of light and dark colors on a display, such as a TV. The displays on the back of cameras are all basically the same nowadays, and any differences in contrast ratio are going to be insignificant or undetectable.
Generally the higher the first number, the better.
There has been a breakthrough in LCD TVS recently. The Samsung LN-T4681F (AVAILABLE ALSO IN 40" AND 52") has a contrast ration of 500,000:1. Impressive. Sony also has an OLED TV with a contrast ratio of 1,000,000:1. When you get to 500,000 you see an almost perfect black. If you have a movie and the screen is black, you might think that the TV is off. When you see the 1,000,000: TV you definitely think it is off. the eye can detect any contrast ratio pretty much. But i think you mean what is the ratio when your eye simply sees black. and that is when you get beyond 500,000:1. It doesn't really get much darker and blacker than that.

The Higher the Better. You will see more detail in the darker part of the picture.
That is called the aspect ratio.
