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
Â» Static Contrast Ratio of 5,000 : 1 or a higher
For LCD Televisions
Â» Static Contrast Ratio of 1,000 : 1 or higher
Â» 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.
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.
Aspect ratio is the height and width of the picture or screen. Sometimes this is called FORMAT. Contrast is how much difference there is between the whitest and blackest part of the picture.
It is the difference between the whitest white and the darkest black in the picture. If you turn the contrast down on any TV set, you have lowered the contrast ratio.
The contrast between true black and true white on the screen. The higher the contrast ratio the better. 1000:1 is better than 700:1. An advertised dynamic contrast ration is much higher than the contrast ratio, but not a true measurement of contrast. Dynamic contrast adjusts the backlighting to give the effect of an overall brighter or darker image.
mega contrast ratio is a brand name of technology used by a electronics company to describe the contrast ratio of the screen
A 12,000:1 contrast ratio is good, but a 50,000:1 would be better.
Contrast Ratio - This is the difference between the lightest and darkest spots that the LCD can display.
Dynamic. Good Luck on your certification.
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"
The contrast ratio measures the difference between the darkest black and the brightest white that can be displayed in a picture. Generally, the greater the contrast ratio, the better the picture - up to a point. Also highly dependent on your lighting conditions. If you have a perfectly black home theater environment, you will notice the contrast much more than in a bright room. Plasmas, in almost all cases, have much better native contrast ratios (and darker blacks) than LCDs, which is why they are preferred by home theater enthusiasts. "Dynamic" contrast ratio is primarily a marketing tool and has little to no usefulness in practice and should be ignored when shopping for a tv. Dynamic contrast is measured by putting the panel into essentially a standby mode with no picture and using that as the baseline for the black (which will be much darker than if a picture was actually being fed to the panel). Do you watch tv in standby mode? Of course not. So this measurement in no way reflects what you will actually experience with the tv.

I'm an engineer, I've been researching this for sometime. The simple answer is it cannot be done, however as we like to do in my field we will give something approximate and conservative to go on. From what I've read and seen if you are being told dynamic contrast ratio it is likely 1000 to 2000 times the static contrast ratio. The multiplier will be different for EVERY brand comparison, but should general fall in this range.
Contrast ratio is the difference between white and black on a given display. The higher the number means there is a larger difference between white and black and will typically look better. See here for a better explanation: http://en.wikipedia.org/wiki/Contrast_ratio
dynamic viscosity is the quantitative expression of fluid's resistance,while kinematic viscosity is the ratio of fluid viscous force to inertial force.
most of the cases the resolution is important when it comes to large screens contrast ratio matters!! i mean lik the very large plasma displays!!
The main difference between plasma and LCD panels is the contrast ratio (deeper blacks the higher the ratio) and the viewing angles (the wider the angle you are to the actual screen, it usually gets worse). Plasma screens usually have better angle viewing and contrast ratio at the expense of a higher power consumption and lower native resolution than LCD panels.

stress is the ratio between the load and area
The contrast ratio is a measure of how much light the projector can pump out. A high contrast ratio is especially important for daylight use.
a ratio is a comparison between 2 things and a proportion is a ratio on each side of the = sign
An odds ratio is the difference between the number of times that something happens and does not happen. An unadjusted odds ratio is a guess between what could or could not happen.
