The contrast ratio is a measurement of the range of brightness can display. Theoretically, the higher the number, the better the image. A high contrast ratio means that whites will be brighter and blacks will be blacker than a lower contrast ratio. It has become an important feature because early LCD and plasma screens had a very poor contrast ratio compared to the older CRT televisions. Modern displays have largely overcome the problem and ratios of 5000 : 1 or more are quite common. However, a high contrast ratio doesn't always indicate how well the screen will display dark grays and near whites. Therefore, the real test is to look at the screen to see how the image looks. A good screen will show lots of detail in dark areas and light areas. A poor one will tend to show less detail and dark areas may show up as blacks rather than a range of grays. To make it very simple, if the picture looks good, then it is good, regardless of the published performance data.

Ratio and use of widescreen television?
The typical width to height aspect ratio for a widescreen television is 4:3. It varies depending on the brand and overall size.
What does 5000 x1 or 20000 x1 mean in regards to HD televisions?
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"
What does the term "pan and scan" mean?
Pan and Scan means adjusting widescreen images so that they can fit into the standard ratio. It is an old television term!
In TV what is the better contrast ratio- 1000 to 1 or 1500 to 1?
1500:1 is the better contrast ratio
Is the ratio of a widescreen closer to a golden rectangle or a normal TV?
The Golden Mean is 1.618, right? "Widescreen" is usually interpreted to mean 16:9, which divides down to 1.78, and "Television ratio" is 4:3, which divides out to 1.3...so a widescreen is closer to the Golden Rectangle. Bonus answer: Laptop computers with 17" displays (usually 1440x900 or 1920x1200 resolution) have nearly exactly the same aspect ratio as the Golden Rectangle -- 1440 divided by 900 is 1.6... which is VERY close, and you can generate a perfect Golden Spiral using the 1440x900 dimensions!
What us dynamic 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.
What is the contrast resolution on the tv?
This item has 1440x900 resolution and 800:1 Contrast Ratio.
What is the most common aspect ratio of TVs sold today?

What benefits does a Dell 2407WFP have?
The Dell 2407WFP is a widescreen LCD monitor. This monitor features a 24" display view, a six millisecond response time, 3000:1 dynamic contrast ratio, and it supports higher definition than HD television.
What is the difference between dynamic and native contrast ratio?
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.
How much dynamic contrast to ratio can the eye see?
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.

What is the best contract ratio for tv?
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.
